iOS开发之将GIF存储本地相册

#import 

1、引用库 

2、将GIF图片转为NSData类型

3、存储代码

        ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init];
        [library writeImageDataToSavedPhotosAlbum:data metadata:nil completionBlock:^(NSURL *assetURL, NSError *error) {
            NSLog(@"Success at %@", [assetURL path] );
        }];
