Simply one line, downloads and shows an image in an UIImageView asynchronously.

Usage

pod 'WKWebImage' and #import <WKWebImage.h>

Method

Include four methods：

// Download and show asynchronously. (default)
- (void)wk_setImageWithURL:(NSURL *)url;

// default + placeholder
- (void)wk_setImageWithURL:(NSURL *)url placeholder:(UIImage *)placeholder;

// default + call back
- (void)wk_setImageWithURL:(NSURL *)url completion:(void (^)(UIImage *image))comletion;

// default + placeholder + call back
- (void)wk_setImageWithURL:(NSURL *)url placeholder:(UIImage *)placeholder completion:(void (^)(UIImage *image))comletion;

e.g.

[_imageView wk_setImageWithURL:[NSURL URLWithString:@"http://7xneqd.com1.z0.glb.clouddn.com/fiveinarow.png"]];

Simply one line! :)

Clear the Cache

WKWebImage will cache the image. Remove them with the below methods:

// Clear the cache in RAM.
[[WKWebImageManager sharedManager] clearMemory];

// Clear the cache in disk.
[[WKWebImageManager sharedManager] clearDisk];

中文说明

一行代码实现UIImageView的异步加载、缓存图片。

演示

pod 'WKWebImage' 并 #import <WKWebImage.h>

异步加载图片

包含以下四种设置方法：

// 异步加载图片
- (void)wk_setImageWithURL:(NSURL *)url;

// 加载 + 设置placeholder
- (void)wk_setImageWithURL:(NSURL *)url placeholder:(UIImage *)placeholder;

// 加载 + 设置回调
- (void)wk_setImageWithURL:(NSURL *)url completion:(void (^)(UIImage *image))comletion;

// 加载 + placeholder + 回调
- (void)wk_setImageWithURL:(NSURL *)url placeholder:(UIImage *)placeholder completion:(void (^)(UIImage *image))comletion;

例如

[_imageView wk_setImageWithURL:[NSURL URLWithString:@"http://7xneqd.com1.z0.glb.clouddn.com/fiveinarow.png"]];

一行代码即可 :)

清除缓存

WKWebImage 会把已加载的图片缓存到本地，如果要清除缓存，可调用以下方法：

// 清除内存中的缓存
[[WKWebImageManager sharedManager] clearMemory];

// 清除本地的缓存
[[WKWebImageManager sharedManager] clearDisk];
