Cannot download Instagram video to camera roll

Question

I am trying to learn the Instagram API and I want to be able to save images and video content to my camera roll. So far the images code works properly but I cant get the video to save to camera roll. Here is my code so far

- (void)downloadButtonPressed:(UIButton *)sender {
if ([self.mediaModel.mediaType isEqualToString:@"video"]) {
    NSURL *videoURL = [NSURL URLWithString:_mediaModel.videoStandardResolutionURL];
    if (UIVideoAtPathIsCompatibleWithSavedPhotosAlbum(videoURL.path)) {
        NSLog(@"compatible");
    } else {
        NSLog(@"not compatible");
    }
    //UISaveVideoAtPathToSavedPhotosAlbum(videoPath, nil, nil, nil);
} else {
    UIImageWriteToSavedPhotosAlbum(self.imageView.image, nil, nil, nil);
}

}

First I check is the media type is a video or not. If not then the image is straightforward to save.

If not I check if the videoURL.path is compatible but this is where I get stuck and I get an error like this:

Video /hphotos-xaf1/t50.2886-16/11803693_1632141970376671_10815617_n.mp4 cannot be saved to the saved photos album: Error Domain=NSURLErrorDomain Code=-1100 "The requested URL was not found on this server."

Would really appreciate the help. Thanks alot!

Don't try to save it directly from the network into the saved photos album. Download it (using NSURLSession and a download task). Then save it from there (i.e., from the local file URL that this gives you) into the saved photos album.
