Save to Photo Album not working

[syedharishussain]

I use the given method for saving GIF to photo album, but it does not animate when i attach the GIF to an email or iMessage. So i instead used below code which seems to work fine for me:

instead of:

UIImage * gif_image = [UIImage imageWithContentsOfFile:tempPath];
UIImageWriteToSavedPhotosAlbum(gif_image, self, nil, nil);

I used:

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

NSData *data = [NSData dataWithContentsOfFile:tempPath];

[library writeImageDataToSavedPhotosAlbum:data metadata:nil completionBlock:^(NSURL *assetURL, NSError *error) {
    if (error) {
        NSLog(@"Error Saving GIF to Photo Album: %@", error);
    } else {
        // TODO: success handling
        NSLog(@"GIF Saved to %@", assetURL);
    }
}];

This seems to work.

But one problem remains, When I attach it to email or iMessage, works fine. But not for sharing on twitter.

as you can see in the screen shot: the keyboard images are GIFs, but twitter does not show them as GIFs (which you can see in Dog GIF there is a 'GIF' label on top left).

What might be the problem?
