ios - UIImagePicker saving photos to multiple albums

Question

Im am trying to capture images and save them to a custom album using UIImagePickerController.TMy problem is that the images are getting saved into the following albums

1) My custom album 2)Camera Roll 3) My Photo Stream

I am using the following code for the image saving part

//Save image in an album with the app's name
        _assetsLibrary = [[ALAssetsLibrary alloc] init];
        [_assetsLibrary saveImage:imageToSave toAlbum:@"My Album" withCompletionBlock:^(NSError *error) {
            if (error!=nil) {
                DLog(@"Big error: %@", [error description]);
            }
        }];

How can i prevent the photos from getting saved as multiple copies??
