一、FLAnimatedImage is a performant animated GIF engine for iOS:

①同时播放多个GIF，播放速度可与桌面浏览器相媲美

②可变帧延迟

③Behaves gracefully under memory pressure

④消除第一次播放循环期间的延迟或阻塞

⑤以与现代浏览器相同的方式解释快速GIF的帧延迟

二、为什么应用FLAnimatedImage？

*尚不支持GIF动画的应用

*已支持动画GIF但需要更高性能解决方案的应用

*People who want to tinker with the code (the corresponding blog postis a great place to start; also see theTo Dosection below)

三、使用方法

FLAnimatedImage是一个封装良好的插入组件。只需使用FLAnimatedImageView实例替换您的UIImageView实例即可获得动画GIF支持。没有要管理的中央缓存或状态。

pod'FLAnimatedImage','~> 1.0'

FLAnimatedImage *image = [FLAnimatedImageanimatedImageWithGIFData:[NSDatadataWithContentsOfURL:[NSURLURLWithString:@"https://upload.wikimedia.org/wikipedia/commons/2/2c/Rotating_earth_%28large%29.gif"]]];

FLAnimatedImageView *imageView = [[FLAnimatedImageViewalloc]init]

;imageView.animatedImage = image;imageView.frame = CGRectMake(0.0,0.0,100.0,100.0);

[self.viewaddSubview:imageView];
