How to implement UITableView`s swipe to delete for UICollectionView

Question

I just like to ask how can I implement the same behavior of UITableView`s swipe to delete in UICollectionView. I am trying to find a tutorial but I cannot find any.

You can try adding a UISwipeGestureRecognizer to each collection cell, like this:

-(UICollectionViewCell *)collectionView:(UICollectionView *)collectionView
             cellForItemAtIndexPath:(NSIndexPath *)indexPath
{
    CollectionViewCell *cell = ...

    UISwipeGestureRecognizer* gestureRecognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(userDidSwipe:)];
    [gestureRecognizer setDirection:UISwipeGestureRecognizerDirectionRight];
    [cell addGestureRecognizer:gestureRecognizer];
}

followed by:

- (void)userDidSwipe:(UIGestureRecognizer *)gestureRecognizer {
    if (gestureRecognizer.state == UIGestureRecognizerStateEnded) {
        //handle the gesture appropriately
    }
}
