This includes animated image loading, rendering, decoding, and also supports customizations (for advanced users). +This animated image solution is available for `iOS`/`tvOS`/`macOS`. The `SDAnimatedImage` is subclass of `UIImage/NSImage`, and `SDAnimatedImageView` is subclass of `UIImageView/NSImageView`, to make them compatible with the common frameworks APIs. See [Animated Image](https://github.com/SDWebImage/SDWebImage/wiki/Advanced-Usage#animated-image-50) for more detailed information. + +#### FLAnimatedImage integration has its own dedicated repo +In order to clean up things and make our core project do less things, we decided that the `FLAnimatedImage` integration does not belong here. From 5.0, this will still be available, but under a dedicated repo [SDWebImageFLPlugin](https://github.com/SDWebImage/SDWebImageFLPlugin). + +## Installation + +There are four ways to use SDWebImage in your project: +- using CocoaPods +- using Carthage +- using Swift Package Manager +- manual install (build frameworks or embed Xcode Project) + +### Installation with CocoaPods + +[CocoaPods](http://cocoapods.org/) is a dependency manager for Objective-C, which automates and simplifies the process of using 3rd-party libraries in your projects. See the [Get Started](http://cocoapods.org/#get_started) section for more details. + +#### Podfile +``` +platform :ios, '8.0' +pod 'SDWebImage', '~> 5.0' +``` + +##### Swift and static framework + +Swift project previously have to use `use_frameworks!` to make all Pods into dynamic framework to let CocoaPods works. + +However, start with `CocoaPods 1.5.0+` (with `Xcode 9+`), which supports to build both Objective-C && Swift code into static framework. You can use modular headers to use SDWebImage as static framework, without the need of `use_frameworks!`: + +``` +platform :ios, '8.0' +# Uncomment the next line when you want all Pods as static framework +# use_modular_headers! +pod 'SDWebImage', :modular_headers => true +``` + +See more on [CocoaPods 1.5.0 — Swift Static Libraries](http://blog.cocoapods.org/CocoaPods-1.5.0/) + +If not, you still need to add `use_frameworks!` to use SDWebImage as dynamic framework: + +``` +platform :ios, '8.0' +use_frameworks! +pod 'SDWebImage' +``` + +#### Subspecs + +There are 2 subspecs available now: `Core` and `MapKit` (this means you can install only some of the SDWebImage modules. By default, you get just `Core`, so if you need `MapKit`, you need to specify it). + +Podfile example: + +``` +pod 'SDWebImage/MapKit' +``` + +### Installation with Carthage (iOS 8+) + +[Carthage](https://github.com/Carthage/Carthage) is a lightweight dependency manager for Swift and Objective-C. It leverages CocoaTouch modules and is less invasive than CocoaPods. + +To install with carthage, follow the instruction on [Carthage](https://github.com/Carthage/Carthage) + +Carthage users can point to this repository and use whichever generated framework they'd like: SDWebImage, SDWebImageMapKit or both. + +Make the following entry in your Cartfile: `github "SDWebImage/SDWebImage"` +Then run `carthage update` +If this is your first time using Carthage in the project, you'll need to go through some additional steps as explained [over at Carthage](https://github.com/Carthage/Carthage#adding-frameworks-to-an-application). + +> NOTE: At this time, Carthage does not provide a way to build only specific repository subcomponents (or equivalent of CocoaPods's subspecs). All components and their dependencies will be built with the above command. However, you don't need to copy frameworks you aren't using into your project. For instance, if you aren't using `SDWebImageMapKit`, feel free to delete that framework from the Carthage Build directory after `carthage update` completes. + +### Installation with Swift Package Manager (Xcode 11+) + +[Swift Package Manager](https://swift.org/package-manager/) (SwiftPM) is a tool for managing the distribution of Swift code as well as C-family dependency. From Xcode 11, SwiftPM got natively integrated with Xcode. + +SDWebImage support SwiftPM from version 5.1.0. To use SwiftPM, you should use Xcode 11 to open your project. Click `File` -> `Swift Packages` -> `Add Package Dependency`, enter [SDWebImage repo's URL](https://github.com/SDWebImage/SDWebImage.git). Or you can login Xcode with your GitHub account and just type `SDWebImage` to search. + +After select the package, you can choose the dependency type (tagged version, branch or commit). Then Xcode will setup all the stuff for you. + +If you're a framework author and use SDWebImage as a dependency, update your `Package.swift` file: + +```swift +let package = Package( + // 5.1.0 ..< 6.0.0 + dependencies: [ + .package(url: "https://github.com/SDWebImage/SDWebImage.git", from: "5.1.0") + ], + // ... +) +``` + +### Manual Installation Guide + +See more on [Manual install Guide](https://github.com/SDWebImage/SDWebImage/wiki/Installation-Guide#manual-installation-guide) + +### Import headers in your source files + +In the source files where you need to use the library, import the umbrella header file: + +```objective-c +#import +``` + +### Build Project + +At this point your workspace should build without error. If you are having problem, post to the Issue and the +community can help you solve it. + +## Author +- [Olivier Poitrey](https://github.com/rs) + +## Collaborators +- [Konstantinos K.](https://github.com/mythodeia) +- [Bogdan Poplauschi](https://github.com/bpoplauschi) +- [Chester Liu](https://github.com/skyline75489) +- [DreamPiggy](https://github.com/dreampiggy) +- [Wu Zhong](https://github.com/zhongwuzw) + +## Credits + +Thank you to all the people who have already contributed to SDWebImage. + +[![Contributors](https://opencollective.com/SDWebImage/contributors.svg?width=890)](https://github.com/SDWebImage/SDWebImage/graphs/contributors) + +## Licenses + +All source code is licensed under the [MIT License](https://github.com/SDWebImage/SDWebImage/blob/master/LICENSE). + +## Architecture + +#### High Level Diagram +

Check our [Wiki](https://github.com/SDWebImage/SDWebImage/wiki/Advanced-Usage) when you need: + +- [x] Animated Image full-stack solution, with balance of CPU && RAM +- [x] Progressive image loading, with animation support +- [x] Reusable download, never request single URL twice +- [x] URL Request / Response Modifier, provide custom HTTP Header +- [x] Image Transformer, apply corner radius or CIFilter +- [x] Multiple caches system, query from different source +- [x] Multiple loaders system, load from different resource + +You can also get all benefits from the existing community around with SDWebImage. You can have massive image format support (GIF/APNG/WebP/HEIF/AVIF/SVG/PDF) via [Coder Plugins](https://github.com/SDWebImage/SDWebImage/wiki/Coder-Plugin-List), PhotoKit support via [SDWebImagePhotosPlugin](https://github.com/SDWebImage/SDWebImagePhotosPlugin), Firebase integration via [FirebaseUI](https://github.com/firebase/FirebaseUI-iOS), etc. + +Besides all these features, we do optimization for SwiftUI, like Binding, View Modifier, using the same design pattern to become a good SwiftUI citizen. + +## Contribution + +This framework is under heavily development, it's recommended to use [the latest release](https://github.com/SDWebImage/SDWebImageSwiftUI/releases) as much as possible (including SDWebImage dependency). + +Note we do not guarantee the public API stable for current status until v1.0 version, to follow [Semantic Versioning](https://semver.org/). + +All issue reports, feature requests, contributions, and GitHub stars are welcomed.

In previous version, `WebImage` supports static image format only, because unlike `UIImageView` in UIKit, SwiftUI's `Image` does not support animated image or vector image. + +Note: From v0.9.0, `WebImage` supports animated image as well! You can use `.animated()` to start animation. This is done by using the native SwiftUI rendering system and SDWebImage's powerful [Animated Player](https://github.com/SDWebImage/SDWebImage/wiki/Advanced-Usage#animated-player-530). But it's still recommend to use `AnimatedImage` for advanced controls like progressive animation rendering, runloop mode, playback rate, etc. + +### Using `AnimatedImage` to play animation + +- [x] Supports network image as well as local data and bundle image +- [x] Supports animated image format as well as vector image format +- [x] Supports animated progressive image loading (like web browser) +- [x] Supports animation control using the SwiftUI Binding +- [x] Supports indicator and transition, powered by SDWebImage and Core Animation +- [x] Supports advanced control like loop count, playback rate, buffer size, runloop mode, etc +- [x] Supports coordinate with native UIKit/AppKit view + +```swift +var body: some View { + Group { + // Network + AnimatedImage(url: URL(string: "https://raw.githubusercontent.com/liyong03/YLGIFImage/master/YLGIFImageDemo/YLGIFImageDemo/joy.gif"), options: [.progressiveLoad]) // Progressive Load + .onFailure { error in + // Error + } + .resizable() // Actually this is not needed unlike SwiftUI.Image + .placeholder(UIImage(systemName: "photo")) // Placeholder Image + .indicator(SDWebImageActivityIndicator.medium) // Activity Indicator + .transition(.fade) // Fade Transition + .scaledToFit() // Attention to call it on AnimatedImage, but not `some View` after View Modifier + + // Data + AnimatedImage(data: try! Data(contentsOf: URL(fileURLWithPath: "/tmp/foo.webp"))) + .customLoopCount(1) // Custom loop count + .playbackRate(2.0) // Playback speed rate + + // Bundle (not Asset Catalog) + AnimatedImage(name: "animation1", isAnimating: $isAnimating)) // Animation control binding + .maxBufferSize(.max) + .onViewUpdate { view, context in // Advanced native view coordinate + view.toolTip = "Mouseover Tip" + } + } +} +``` + +Note: `AnimatedImage` supports both image url or image data for animated image format. Which use the SDWebImage's [Animated ImageView](https://github.com/SDWebImage/SDWebImage/wiki/Advanced-Usage#animated-image-50) for internal implementation. Pay attention that since this base on UIKit/AppKit representable, some advanced SwiftUI layout and animation system may not work as expected. You may need UIKit/AppKit and Core Animation to modify the native view. + +Note: From v0.9.0, `AnimatedImage` on watchOS drop the supports on watchOS, because of using hacks and private APIs. For watchOS user, choose `WebImage` instead. + +Note: From v0.8.0, `AnimatedImage` on watchOS support all features the same as iOS/tvOS/macOS, including Animated WebP rendering, runloop mode, pausable, purgeable, playback rate, etc. It use the SDWebImage's [Animated Player](https://github.com/SDWebImage/SDWebImage/wiki/Advanced-Usage#animated-player-530), which is the same backend engine for iOS/tvOS/macOS's Animated ImageView. + +### Which View to choose + +Why we have two different View types here, is because of current SwiftUI limit. But we're aimed to provide best solution for all use cases. + +If you don't need animated image, prefer to use `WebImage` firstly. Which behaves the seamless as built-in SwiftUI View. If SwiftUI works, it works. + +If you need simple animated image, use v0.9.0 above with `WebImage`. Which provide the basic animated image support. But it does not support progressive animation rendering, playback rate, etc. + +If you need powerful animated image, `AnimatedImage` is the one to choose. Remember it supports static image as well, you don't need to check the format, just use as it. + +But, because `AnimatedImage` use `UIViewRepresentable` and driven by UIKit, currently there may be some small incompatible issues between UIKit and SwiftUI layout and animation system, or bugs related to SwiftUI itself. We try our best to match SwiftUI behavior, and provide the same API as `WebImage`, which make it easy to switch between these two types if needed. + +### Customization and configuration setup + +This framework is based on SDWebImage, which supports advanced customization and configuration to meet different users' demand. + +You can register multiple coder plugins for external image format. You can register multiple caches (different paths and config), multiple loaders (URLSession and Photos URLs). You can control the cache expiration date, size, download priority, etc. All in our [wiki](https://github.com/SDWebImage/SDWebImage/wiki/). + +The best place to put these setup code for SwiftUI App, it's the `AppDelegate.swift`: + +```swift +func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool { + // Add WebP/SVG/PDF support + SDImageCodersManager.shared.addCoder(SDImageWebPCoder.shared) + SDImageCodersManager.shared.addCoder(SDImageSVGCoder.shared) + SDImageCodersManager.shared.addCoder(SDImagePDFCoder.shared) + + // Add default HTTP header + SDWebImageDownloader.shared.setValue("image/webp,image/apng,image/*,*/*;q=0.8", forHTTPHeaderField: "Accept") + + // Add multiple caches + let cache = SDImageCache(namespace: "tiny") + cache.config.maxMemoryCost = 100 * 1024 * 1024 // 100MB memory + cache.config.maxDiskSize = 50 * 1024 * 1024 // 50MB disk + SDImageCachesManager.shared.addCache(cache) + SDWebImageManager.defaultImageCache = SDImageCachesManager.shared + + // Add multiple loaders with Photos Asset support + SDImageLoadersManager.shared.addLoader(SDImagePhotosLoader.shared) + SDWebImageManager.defaultImageLoader = SDImageLoadersManager.shared + return true +} +``` + +For more information, it's really recommended to check our demo, to learn detailed API usage. You can also have a check at the latest API documentation, for advanced usage. + +## Documentation + ++ [SDWebImageSwiftUI API documentation](https://sdwebimage.github.io/SDWebImageSwiftUI/) ++ [SDWebImage API documentation](https://sdwebimage.github.io/) + +## FAQ + +### Common Problems + +#### Using Image/WebImage/AnimatedImage in Button/NavigationLink + +SwiftUI's `Button` apply overlay to its content (except `Text`) by default, this is common mistake to write code like this, which cause strange behavior: + +```swift +// Wrong +Button(action: { + // Clicked +}) { + WebImage(url: url) +} +// NavigationLink create Button implicitly +NavigationView { + NavigationLink(destination: Text("Detail view here")) { + WebImage(url: url) + } +} +``` + +Instead, you must override the `.buttonStyle` to use the plain style, or the `.renderingMode` to use original mode. You can also use the `.onTapGesture` modifier for touch handling. See [How to disable the overlay color for images inside Button and NavigationLink](https://www.hackingwithswift.com/quick-start/swiftui/how-to-disable-the-overlay-color-for-images-inside-button-and-navigationlink) + +```swift +// Correct +Button(action: { + // Clicked +}) { + WebImage(url: url) +} +.buttonStyle(PlainButtonStyle()) +// Or +NavigationView { + NavigationLink(destination: Text("Detail view here")) { + WebImage(url: url) + .renderingMode(.original) + } +} +``` + +#### Using for backward deployment and weak linking SwiftUI + +SDWebImageSwiftUI from v0.10.0, supports to use when your App Target has a deployment target version less than iOS 13/macOS 10.15/tvOS 13/watchOS 6. Which will weak linking of SwiftUI(Combine) to allows writing code with available check at runtime. + +To use backward deployment, you have to do the follow things: + ++ Add `-weak_framework SwiftUI -weak_framework Combine` in your App Target's `Other Linker Flags` build setting + +You should notice that all the third party SwiftUI frameworks should have this build setting as well, not only just SDWebImageSwiftUI (we already added in v0.10.0). Or when running on iOS 12 device, it will trigger the runtime dyld error on startup. + ++ Use CocoaPods or Carthage (SwiftPM does not support weak linking nor backward deployment currently) + +For Carthage user, the built binary framework will use [Library Evolution](https://swift.org/blog/abi-stability-and-more/) to support for backward deployment. + +For CocoaPods user, you can skip the platform version validation in Podfile with: + +```ruby +platform :ios, '13.0' # This does not effect your App Target's deployment target version, just a hint for CocoaPods +``` + ++ Add **all the SwiftUI code** with the available annotation and runtime check, like this: + +```swift +// AppDelegate.swift +func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool { + // ... + if #available(iOS 13, *) { + window.rootViewController = UIHostingController(rootView: ContentView()) + } else { + window.rootViewController = ViewController() + } + // ... +} + +// ViewController.swift +class ViewController: UIViewController { + var label: UILabel = UILabel() + override func viewDidLoad() { + super.viewDidLoad() + view.backgroundColor = .white + view.addSubview(label) + label.text = "Hello World iOS 12!" + label.sizeToFit() + label.center = view.center + } +} + +// ContentView.swift +@available(iOS 13.0, OSX 10.15, tvOS 13.0, watchOS 6.0, *) +struct ContentView : View { + var body: some View { + Group { + Text("Hello World iOS 13!") + WebImage(url: URL(string: "https://i.loli.net/2019/09/24/rX2RkVWeGKIuJvc.jpg")) + } + } +} +``` + +## Demo + +To run the example using SwiftUI, following the steps: + +``` +cd Example +pod install +``` + +Then open the Xcode Workspace to run the demo application. + +Since SwiftUI is aimed to support all Apple platforms, our demo does this as well, one codebase including: + ++ iOS (iPhone/iPad/Mac Catalyst) ++ macOS ++ tvOS ++ watchOS + +Demo Tips: + +1.

First, add the following line to your [Podfile](http://guides.cocoapods.org/using/using-cocoapods.html): + +```ruby +pod 'SVProgressHUD' +``` + +If you want to use the latest features of `SVProgressHUD` use normal external source dependencies. + +```ruby +pod 'SVProgressHUD', :git => 'https://github.com/SVProgressHUD/SVProgressHUD.git' +``` + +This pulls from the `master` branch directly. + +Second, install `SVProgressHUD` into your project: + +```ruby +pod install +``` + +### Carthage + +[Carthage](https://github.com/Carthage/Carthage) is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks. To integrate `SVProgressHUD` into your Xcode project using Carthage, specify it in your `Cartfile`: + +```ogdl +github "SVProgressHUD/SVProgressHUD" +``` + +Run `carthage bootstrap` to build the framework in your repository's Carthage directory. You can then include it in your target's `carthage copy-frameworks` build phase.

Only use it if you absolutely need to perform a task before taking the user forward. Bad use case examples: pull to refresh, infinite scrolling, sending message.** + +Using `SVProgressHUD` in your app will usually look as simple as this (using Grand Central Dispatch): + +```objective-c +[SVProgressHUD show]; +dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{ + // time-consuming task + dispatch_async(dispatch_get_main_queue(), ^{ + [SVProgressHUD dismiss]; + }); +}); +``` + +### Showing the HUD + +You can show the status of indeterminate tasks using one of the following: + +```objective-c ++ (void)show; ++ (void)showWithStatus:(NSString*)string; +``` + +If you'd like the HUD to reflect the progress of a task, use one of these: + +```objective-c ++ (void)showProgress:(CGFloat)progress; ++ (void)showProgress:(CGFloat)progress status:(NSString*)status; +``` + +### Dismissing the HUD + +The HUD can be dismissed using: + +```objective-c ++ (void)dismiss; ++ (void)dismissWithDelay:(NSTimeInterval)delay; +``` + +If you'd like to stack HUDs, you can balance out every show call using: + +``` ++ (void)popActivity; +``` + +The HUD will get dismissed once the popActivity calls will match the number of show calls. + +Or show a confirmation glyph before before getting dismissed a little bit later. The display time depends on `minimumDismissTimeInterval` and the length of the given string. + +```objective-c ++ (void)showInfoWithStatus:(NSString*)string; ++ (void)showSuccessWithStatus:(NSString*)string; ++ (void)showErrorWithStatus:(NSString*)string; ++ (void)showImage:(UIImage*)image status:(NSString*)string; +``` + +## Customization + +`SVProgressHUD` can be customized via the following methods: + +```objective-c ++ (void)setDefaultStyle:(SVProgressHUDStyle)style; // default is SVProgressHUDStyleLight ++ (void)setDefaultMaskType:(SVProgressHUDMaskType)maskType; // default is SVProgressHUDMaskTypeNone ++ (void)setDefaultAnimationType:(SVProgressHUDAnimationType)type; // default is SVProgressHUDAnimationTypeFlat ++ (void)setContainerView:(UIView*)containerView; // default is window level ++ (void)setMinimumSize:(CGSize)minimumSize; // default is CGSizeZero, can be used to avoid resizing ++ (void)setRingThickness:(CGFloat)width; // default is 2 pt ++ (void)setRingRadius:(CGFloat)radius; // default is 18 pt ++ (void)setRingNoTextRadius:(CGFloat)radius; // default is 24 pt ++ (void)setCornerRadius:(CGFloat)cornerRadius; // default is 14 pt ++ (void)setBorderColor:(nonnull UIColor*)color; // default is nil ++ (void)setBorderWidth:(CGFloat)width; // default is 0 ++ (void)setFont:(UIFont*)font; // default is [UIFont preferredFontForTextStyle:UIFontTextStyleSubheadline] ++ (void)setForegroundColor:(UIColor*)color; // default is [UIColor blackColor], only used for SVProgressHUDStyleCustom ++ (void)setBackgroundColor:(UIColor*)color; // default is [UIColor whiteColor], only used for SVProgressHUDStyleCustom ++ (void)setBackgroundLayerColor:(UIColor*)color; // default is [UIColor colorWithWhite:0 alpha:0.4], only used for SVProgressHUDMaskTypeCustom ++ (void)setImageViewSize:(CGSize)size; // default is 28x28 pt ++ (void)setShouldTintImages:(BOOL)shouldTintImages; // default is YES ++ (void)setInfoImage:(UIImage*)image; // default is the bundled info image provided by Freepik ++ (void)setSuccessImage:(UIImage*)image; // default is bundled success image from Freepik ++ (void)setErrorImage:(UIImage*)image; // default is bundled error image from Freepik ++ (void)setViewForExtension:(UIView*)view; // default is nil, only used if #define SV_APP_EXTENSIONS is set ++ (void)setGraceTimeInterval:(NSTimeInterval)interval; // default is 0 seconds ++ (void)setMinimumDismissTimeInterval:(NSTimeInterval)interval; // default is 5.0 seconds ++ (void)setMaximumDismissTimeInterval:(NSTimeInterval)interval; // default is CGFLOAT_MAX ++ (void)setFadeInAnimationDuration:(NSTimeInterval)duration; // default is 0.15 seconds ++ (void)setFadeOutAnimationDuration:(NSTimeInterval)duration; // default is 0.15 seconds ++ (void)setMaxSupportedWindowLevel:(UIWindowLevel)windowLevel; // default is UIWindowLevelNormal ++ (void)setHapticsEnabled:(BOOL)hapticsEnabled; // default is NO +``` + +Additionally `SVProgressHUD` supports the `UIAppearance` protocol for most of the above methods. + +### Hint + +As standard `SVProgressHUD` offers two preconfigured styles: + +* `SVProgressHUDStyleLight`: White background with black spinner and text +* `SVProgressHUDStyleDark`: Black background with white spinner and text + +If you want to use custom colors use `setForegroundColor` and `setBackgroundColor:`. These implicitly set the HUD's style to `SVProgressHUDStyleCustom`. + +## Haptic Feedback + +For users with newer devices (starting with the iPhone 7), `SVProgressHUD` can automatically trigger haptic feedback depending on which HUD is being displayed. The feedback maps as follows: + +* `showSuccessWithStatus:` <-> `UINotificationFeedbackTypeSuccess` +* `showInfoWithStatus:` <-> `UINotificationFeedbackTypeWarning` +* `showErrorWithStatus:` <-> `UINotificationFeedbackTypeError` + +To enable this functionality, use `setHapticsEnabled:`. + +Users with devices prior to iPhone 7 will have no change in functionality. + +## Notifications + +`SVProgressHUD` posts four notifications via `NSNotificationCenter` in response to being shown/dismissed: +* `SVProgressHUDWillAppearNotification` when the show animation starts +* `SVProgressHUDDidAppearNotification` when the show animation completes +* `SVProgressHUDWillDisappearNotification` when the dismiss animation starts +* `SVProgressHUDDidDisappearNotification` when the dismiss animation completes + +Each notification passes a `userInfo` dictionary holding the HUD's status string (if any), retrievable via `SVProgressHUDStatusUserInfoKey`. + +`SVProgressHUD` also posts `SVProgressHUDDidReceiveTouchEventNotification` when users touch on the overall screen or `SVProgressHUDDidTouchDownInsideNotification` when a user touches on the HUD directly. For this notifications `userInfo` is not passed but the object parameter contains the `UIEvent` that related to the touch. + +## App Extensions + +When using `SVProgressHUD` in an App Extension, `#define SV_APP_EXTENSIONS` to avoid using unavailable APIs. Additionally call `setViewForExtension:` from your extensions view controller with `self.view`. + +## Contributing to this project + +If you have feature requests or bug reports, feel free to help out by sending pull requests or by [creating new issues](https://github.com/SVProgressHUD/SVProgressHUD/issues/new).
