YYWebImage is an asynchronous image loading framework (a component of [YYKit](https://github.com/ibireme/YYKit)).
It was created as an improved replacement for SDWebImage, PINRemoteImage and FLAnimatedImage.
It use [YYCache](https://github.com/ibireme/YYCache) to support memory and disk cache, and [YYImage](https://github.com/ibireme/YYImage) to support WebP/APNG/GIF image decode.
See these project for more information.
Features
==============
- Asynchronous image load from remote or local URL.
- Animated WebP, APNG, GIF support (dynamic buffer, lower memory usage).
- Baseline/progressive/interlaced image decode support.
- Image loading category for UIImageView, UIButton, MKAnnotationView and CALayer.
- Image effect: blur, round corner, resize, color tint, crop, rotate and more.
- High performance memory and disk image cache.
- High performance image loader to avoid main thread blocked.
- Fully documented.
Usage
==============
### Load image from URL
```objc
// load from remote url
imageView.yy_imageURL = [NSURL URLWithString:@"http://github.com/logo.png"];
// load from local url
imageView.yy_imageURL = [NSURL fileURLWithPath:@"/tmp/logo.png"];
```
### Load animated image
```objc
// just replace `UIImageView` with `YYAnimatedImageView`
UIImageView *imageView = [YYAnimatedImageView new];
imageView.yy_imageURL = [NSURL URLWithString:@"http://github.com/ani.webp"];
```
### Load image progressively
```objc
// progressive
[imageView yy_setImageWithURL:url options:YYWebImageOptionProgressive];
// progressive with blur and fade animation (see the demo at the top of this page)
[imageView yy_setImageWithURL:url options:YYWebImageOptionProgressiveBlur ｜ YYWebImageOptionSetImageWithFadeAnimation];
```
### Load and process image
```objc
// 1. download image from remote
// 2. get download progress
// 3. resize image and add round corner
// 4. set image with a fade animation
[imageView yy_setImageWithURL:url
placeholder:nil
options:YYWebImageOptionSetImageWithFadeAnimation
progress:^(NSInteger receivedSize, NSInteger expectedSize) {
progress = (float)receivedSize / expectedSize;
}
transform:^UIImage *(UIImage *image, NSURL *url) {
image = [image yy_imageByResizeToSize:CGSizeMake(100, 100) contentMode:UIViewContentModeCenter];
return [image yy_imageByRoundCornerRadius:10];
}
completion:^(UIImage *image, NSURL *url, YYWebImageFromType from, YYWebImageStage stage, NSError *error) {
if (from == YYWebImageFromDiskCache) {
NSLog(@"load from disk cache");
}
}];
```
### Image Cache
```objc
YYImageCache *cache = [YYWebImageManager sharedManager].cache;
// get cache capacity
cache.memoryCache.totalCost;
cache.memoryCache.totalCount;
cache.diskCache.totalCost;
cache.diskCache.totalCount;
// clear cache
[cache.memoryCache removeAllObjects];
[cache.diskCache removeAllObjects];
// clear disk cache with progress
[cache.diskCache removeAllObjectsWithProgressBlock:^(int removedCount, int totalCount) {
// progress
} endBlock:^(BOOL error) {
// end
}];
```
Installation
==============
### CocoaPods
1. Update cocoapods to the latest version.
2. Add `pod 'YYWebImage'` to your Podfile.
3. Run `pod install` or `pod update`.
4. Import \.
5. Notice: it doesn't include WebP subspec by default, if you want to support WebP format, you may add `pod 'YYImage/WebP'` to your Podfile. You may call `YYImageWebPAvailable()` to check whether the WebP subspec is installed correctly.
### Carthage
1. Add `github "ibireme/YYWebImage"` to your Cartfile.
2. Run `carthage update --platform ios` and add the framework to your project.
3. Import \.
4. Notice: carthage framework doesn't include webp component, if you want to support WebP format, use CocoaPods or install manually. You may call `YYImageWebPAvailable()` to check whether the WebP library is installed correctly.
### Manually
1. Download all the files in the YYWebImage subdirectory.
2. Add the source files to your Xcode project.
3. Link with required frameworks:
* UIKit
* CoreFoundation
* QuartzCore
* AssetsLibrary
* ImageIO
* Accelerate
* MobileCoreServices
* sqlite3
* libz
4. Import `YYWebImage.h`.
5. Notice: if you want to support WebP format, you may add `Vendor/WebP.framework`(static library) to your Xcode project.

中文介绍
==============
YYWebImage 是一个异步图片加载框架 ([YYKit](https://github.com/ibireme/YYKit) 组件之一).
其设计目的是试图替代 SDWebImage、PINRemoteImage、FLAnimatedImage 等开源框架，它支持这些开源框架的大部分功能，同时增加了大量新特性、并且有不小的性能提升。
它底层用 [YYCache](https://github.com/ibireme/YYCache) 实现了内存和磁盘缓存, 用 [YYImage](https://github.com/ibireme/YYImage) 实现了 WebP/APNG/GIF 动图的解码和播放。
你可以查看这些项目以获得更多信息。
特性
==============
- 异步的图片加载，支持 HTTP 和本地文件。
- 支持 GIF、APNG、WebP 动画（动态缓存，低内存占用）。
- 支持逐行扫描、隔行扫描、渐进式图像加载。
- UIImageView、UIButton、MKAnnotationView、CALayer 的 Category 方法支持。
- 常见图片处理：模糊、圆角、大小调整、裁切、旋转、色调等。
- 高性能的内存和磁盘缓存。
- 高性能的图片设置方式，以避免主线程阻塞。
- 每个类和方法都有完善的文档注释。
用法
==============
### 从 URL 加载图片
```objc
// 加载网络图片
imageView.yy_imageURL = [NSURL URLWithString:@"http://github.com/logo.png"];
// 加载本地图片
imageView.yy_imageURL = [NSURL fileURLWithPath:@"/tmp/logo.png"];
```
### 加载动图
```objc
// 只需要把 `UIImageView` 替换为 `YYAnimatedImageView` 即可。
UIImageView *imageView = [YYAnimatedImageView new];
imageView.yy_imageURL = [NSURL URLWithString:@"http://github.com/ani.webp"];
```
### 渐进式图片加载
```objc
// 渐进式：边下载边显示
[imageView yy_setImageWithURL:url options:YYWebImageOptionProgressive];
// 渐进式加载，增加模糊效果和渐变动画 （见本页最上方的GIF演示）
[imageView yy_setImageWithURL:url options:YYWebImageOptionProgressiveBlur ｜ YYWebImageOptionSetImageWithFadeAnimation];
```
### 加载、处理图片
```objc
// 1. 下载图片
// 2. 获得图片下载进度
// 3. 调整图片大小、加圆角
// 4. 显示图片时增加一个淡入动画，以获得更好的用户体验
[imageView yy_setImageWithURL:url
placeholder:nil
options:YYWebImageOptionSetImageWithFadeAnimation
progress:^(NSInteger receivedSize, NSInteger expectedSize) {
progress = (float)receivedSize / expectedSize;
}
transform:^UIImage *(UIImage *image, NSURL *url) {
image = [image yy_imageByResizeToSize:CGSizeMake(100, 100) contentMode:UIViewContentModeCenter];
return [image yy_imageByRoundCornerRadius:10];
}
completion:^(UIImage *image, NSURL *url, YYWebImageFromType from, YYWebImageStage stage, NSError *error) {
if (from == YYWebImageFromDiskCache) {
NSLog(@"load from disk cache");
}
}];
```
### 图片缓存
```objc
YYImageCache *cache = [YYWebImageManager sharedManager].cache;
// 获取缓存大小
cache.memoryCache.totalCost;
cache.memoryCache.totalCount;
cache.diskCache.totalCost;
cache.diskCache.totalCount;
// 清空缓存
[cache.memoryCache removeAllObjects];
[cache.diskCache removeAllObjects];
// 清空磁盘缓存，带进度回调
[cache.diskCache removeAllObjectsWithProgressBlock:^(int removedCount, int totalCount) {
// progress
} endBlock:^(BOOL error) {
// end
}];
```
