How to save the videos in Partcular folder in iPhone Gallery in Objective-C

Question

I have more than 10 videos url in one view which is coming from Web service. I am showing these videos thumbnails in UITableview. I am Using following code where I m Saving These Videos to gallery in particular folder

This is my code::

NSURL *url = [NSURL URLWithString:Urlstr];
NSData *data = [NSData dataWithContentsOfURL:url];

// Write it to cache directory
NSString *path = [[NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES) objectAtIndex:0] stringByAppendingPathComponent:@"file.mov"];
[data writeToFile:path atomically:YES];
// After that use this path to save it to PhotoLibrary
ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init];
[library addAssetsGroupAlbumWithName:@"MyFolderName" resultBlock:^(ALAssetsGroup *group)
 {
     //How to get the album URL?
     // saving the video in  gallery though file path and document directory
     [library writeVideoAtPathToSavedPhotosAlbum:[NSURL fileURLWithPath:path] completionBlock:^(NSURL *assetURL, NSError *error) {

         if (error) {
             NSLog(@"%@", error.description);
         }else {
             NSLog(@"Done :)");
         }
     }];
 }
    failureBlock:^(NSError *error) {
                            //Handle the error
                        }];

Now the issues is it is not saving my video to My folder. But it creates the folder and saving the video in default video folder of gallery.

Anyone please suggest me why it going like this.

Why don't you use or get a hint from https://github.com/Kjuly/ALAssetsLibrary-CustomPhotoAlbum — Poles, Dec 01 '16 at 09:05
