处理方法：

NSURL *imageRefURL = [info valueForKey:UIImagePickerControllerReferenceURL];ALAssetsLibrary* assetLibrary = [[ALAssetsLibrary alloc] init];void (^ALAssetsLibraryAssetForURLResultBlock)(ALAsset *) = ^(ALAsset *asset) {if (asset != nil) {ALAssetRepresentation *rep = [asset defaultRepresentation];Byte imageBuffer = (Byte)malloc(rep.size);NSUInteger bufferSize = [rep getBytes:imageBuffer fromOffset:0.0 length:rep.size error:nil];NSData *imageData = [NSData dataWithBytesNoCopy:imageBuffer length:bufferSize freeWhenDone:YES];// 这个imageData就是gif的了} else {}};[assetLibrary assetForURL:imageRefURLresultBlock:ALAssetsLibraryAssetForURLResultBlockfailureBlock:^(NSError *error){}]; info来源如下：
