我的方法比较简单，直接使用AF下载图片到本地，然后在imageView中通过调用SDWebImage来播放Gif图片。

//部分关键代码如下：#import "UIImage+GIF.h"@property (nonatomic, strong) AFHTTPRequestOperationManager *afManager;- (void)viewDidLoad:(BOOL)animation{    [superviewDidLoad:animation];        //...    //...        if ([imageUrlStr containsString:@".gif"]) {        [self downLoadGifImage:imageUrlStr AndImageView:tImageView];    }else{        [tImageView sd_setImageWithURL:[NSURL URLWithString:imageUrlStr]];    }}- (void)downLoadGifImage:(NSString *)urlImageStr AndImageView:(UIImageView *)imageView{            if (!self.afManager) {        self.afManager = [AFHTTPRequestOperationManager manager];        self.afManager.responseSerializer = [AFHTTPResponseSerializer serializer];    }        [self.afManager GET:urlImageStr parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {                [imageView setImage:[UIImage sd_animatedGIFWithData:responseObject]];            } failure:^(AFHTTPRequestOperation *operation, NSError *error) {        NSLog(@"这么烂的网络还想看git，洗洗睡吧");    }];}
