For convenience, we added categories for UI elements like `UIImageView`, `UIButton`, `MKAnnotationView`. ## Features - [x] Categories for `UIImageView`, `UIButton`, `MKAnnotationView` adding web image and cache management - [x] An asynchronous image downloader - [x] An asynchronous memory + disk image caching with automatic cache expiration handling - [x] A background image decompression - [x] A guarantee that the same URL won't be downloaded several times - [x] A guarantee that bogus URLs won't be retried again and again - [x] A guarantee that main thread will never be blocked - [x] Performances! - [x] Use GCD and ARC ## Supported Image Formats - Image formats supported by UIImage (JPEG, PNG, ...), including GIF - WebP format, including animated WebP (use the `WebP` subspec) ## Requirements - iOS 7.0 or later - tvOS 9.0 or later - watchOS 2.0 or later - OS X 10.8 or later - Xcode 7.3 or later #### Backwards compatibility - For iOS 5 and 6, use [any 3.x version up to 3.7.6](https://github.com/rs/SDWebImage/tree/3.7.6) - For iOS < 5.0, please use the last [2.0 version](https://github.com/rs/SDWebImage/tree/2.0-compat). ## Getting Started - Read this Readme doc - Read the [How to use section](https://github.com/rs/SDWebImage#how-to-use) - Read the [documentation @ CocoaDocs](http://cocoadocs.org/docsets/SDWebImage/) - Read [How is SDWebImage better than X?](https://github.com/rs/SDWebImage/wiki/How-is-SDWebImage-better-than-X%3F) - Try the example by downloading the project from Github or even easier using CocoaPods try `pod try SDWebImage` - Get to the [installation steps](https://github.com/rs/SDWebImage#installation) - Read the [SDWebImage 4.0 Migration Guide](Docs/SDWebImage-4.0-Migration-guide.md) to get an idea of the changes from 3.x to 4.x ## Who Uses It - Find out [who uses SDWebImage](https://github.com/rs/SDWebImage/wiki/Who-Uses-SDWebImage) and add your app to the list. ## Communication - If you **need help**, use [Stack Overflow](http://stackoverflow.com/questions/tagged/sdwebimage). (Tag 'sdwebimage') - If you'd like to **ask a general question**, use [Stack Overflow](http://stackoverflow.com/questions/tagged/sdwebimage). - If you **found a bug**, open an issue. - If you **have a feature request**, open an issue. - If you **want to contribute**, submit a pull request. ## How To Use ```objective-c Objective-C: #import ... [imageView sd_setImageWithURL:[NSURL URLWithString:@"http://www.domain.com/path/to/image.jpg"] placeholderImage:[UIImage imageNamed:@"placeholder.png"]]; ``` ```swift Swift: import SDWebImage imageView.sd_setImage(with: URL(string: "http://www.domain.com/path/to/image.jpg"), placeholderImage: UIImage(named: "placeholder.png")) ``` - For details about how to use the library and clear examples, see [The detailed How to use](Docs/HowToUse.md) ## Animated Images (GIF) support - Starting with the 4.0 version, we rely on [FLAnimatedImage](https://github.com/Flipboard/FLAnimatedImage) to take care of our animated images. - If you use cocoapods, add `pod 'SDWebImage/GIF'` to your podfile. - To use it, simply make sure you use `FLAnimatedImageView` instead of `UIImageView`. - **Note**: there is a backwards compatible feature, so if you are still trying to load a GIF into a `UIImageView`, it will only show the 1st frame as a static image. - **Important**: FLAnimatedImage only works on the iOS platform. For OS X, use `NSImageView` with `animates` set to `YES` to show the entire animated images and `NO` to only show the 1st frame. For all the other platforms (tvOS, watchOS) we will fallback to the backwards compatibility feature described above ## Common Problems ### Using dynamic image size with UITableViewCell UITableView determines the size of the image by the first image set for a cell. If your remote images don't have the same size as your placeholder image, you may experience strange anamorphic scaling issue. The following article gives a way to workaround this issue: [http://www.wrichards.com/blog/2011/11/sdwebimage-fixed-width-cell-images/](http://www.wrichards.com/blog/2011/11/sdwebimage-fixed-width-cell-images/) ### Handle image refresh SDWebImage does very aggressive caching by default. It ignores all kind of caching control header returned by the HTTP server and cache the returned images with no time restriction. It implies your images URLs are static URLs pointing to images that never change. If the pointed image happen to change, some parts of the URL should change accordingly. If you don't control the image server you're using, you may not be able to change the URL when its content is updated. This is the case for Facebook avatar URLs for instance. In such case, you may use the `SDWebImageRefreshCached` flag. This will slightly degrade the performance but will respect the HTTP caching control headers: ``` objective-c [imageView sd_setImageWithURL:[NSURL URLWithString:@"https://graph.facebook.com/olivier.poitrey/picture"] placeholderImage:[UIImage imageNamed:@"avatar-placeholder.png"] options:SDWebImageRefreshCached]; ``` ### Add a progress indicator Add these before you call ```sd_setImageWithURL``` ``` objective-c [imageView sd_setShowActivityIndicatorView:YES]; [imageView sd_setIndicatorStyle:UIActivityIndicatorViewStyleGray]; ``` ``` swift imageView.sd_setShowActivityIndicatorView(true) imageView.sd_setIndicatorStyle(.Gray) ``` ## Installation There are three ways to use SDWebImage in your project: - using CocoaPods - using Carthage - by cloning the project into your repository ### 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, '7.0' pod 'SDWebImage', '~> 4.0' ``` If you are using Swift, be sure to add `use_frameworks!` and set your target to iOS 8+: ``` platform :ios, '8.0' use_frameworks! ``` #### Subspecs There are 4 subspecs available now: `Core`, `MapKit`, `GIF` and `WebP` (this means you can install only some of the SDWebImage modules. By default, you get just `Core`, so if you need `WebP`, you need to specify it). Podfile example: ``` pod 'SDWebImage/WebP' ``` ### 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) #### Cartfile ``` github "rs/SDWebImage" ``` ### Installation by cloning the repository - see [Manual install](Docs/ManualInstallation.md) ### Import headers in your source files In the source files where you need to use the library, import the 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) ## Licenses All source code is licensed under the [MIT License](https://raw.github.com/rs/SDWebImage/master/LICENSE). ## Architecture

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 update` to build the framework and drag the built `SVProgressHUD.framework` (in Carthage/Build/iOS folder) into your Xcode project (Linked Frameworks and Libraries in `Targets`). ### Manually * Drag the `SVProgressHUD/SVProgressHUD` folder into your project. * Take care that `SVProgressHUD.bundle` is added to `Targets->Build Phases->Copy Bundle Resources`. * Add the **QuartzCore** framework to your project. ## Swift Even though `SVProgressHUD` is written in Objective-C, it can be used in Swift with no hassle. If you use [CocoaPods](http://cocoapods.org) add the following line to your [Podfile](http://guides.cocoapods.org/using/using-cocoapods.html): ```ruby use_frameworks! ``` If you added `SVProgressHUD` manually, just add a [bridging header](https://developer.apple.com/library/content/documentation/Swift/Conceptual/BuildingCocoaApps/MixandMatch.html) file to your project with the `SVProgressHUD` header included. ## Usage (see sample Xcode project in `/Demo`) `SVProgressHUD` is created as a singleton (i.e. it doesn't need to be explicitly allocated and instantiated; you directly call `[SVProgressHUD method]`). **Use `SVProgressHUD` wisely! 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)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 implicity 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).

[CocoaPods](https://cocoapods.org/)安装： ``` pod 'HUPhotoBrowser' ``` 2. 下载ZIP包,将`HUPhotoBrowser`资源文件拖到工程中。 3. 将`HUPhotoBrowser.xcodeproj`工程文件和`HUPhotoBrowser`源文件一同拖入工程目录下，在工程中右键选择 "Add Files to ..."，选择`HUPhotoBrowser.xcodeproj`。 ![](http://image18-c.poco.cn/mypoco/myphoto/20170320/12/18436043320170320121521061.jpg?542x710_120) 然后在 "Build Settings -> Header Search Paths" 中添加源文件路径。 ## 其他 为了不影响您项目中导入的其他第三方库，本库没有导入任何其他的第三方内容，可以放心使用。在使用前，您可以查看[示例程序](https://github.com/hujewelz/HUPhotoBrowser/tree/master/Example) * 如果在使用过程中遇到BUG，希望你能Issues我，谢谢（或者尝试下载最新的框架代码看看BUG修复没有） * 如果您有什么建议可以Issues我，谢谢 * 后续我会持续更新，为它添加更多的功能，欢迎star :)
