ios保存动态图片

 

UIImageWriteToSavedPhotosAlbum([UIImage imageWithData:ImageData], self,                                     @selector(image:didFinishSavingWithError:contextInfo:), nil);

 

 

 

但是当图片是Gif格式时，这种方法就不行了，因为UIImage是不支持Gif格式的，

这时我们只好使用以下方法：

 

ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init];

        [library writeImageDataToSavedPhotosAlbum:ImageData metadata:nil completionBlock:^(NSURL *assetURL, NSError *error) {

            // Continue as normal...

        }];

        [library release];

 

 

 

ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init];

        [library writeImageDataToSavedPhotosAlbum:ImageData metadata:nil completionBlock:^(NSURL *assetURL, NSError *error) {

            // Continue as normal...

        }];

        [library release];
