Long press tap gesture recogniser for UICollectionView Objective-c

Question

I am using a UICollectionView in my ViewController for displaying images and i want that user should be able to delete photos on long press, but i am not able to detect long press gesture. I have read all the previous discussions and tried to implement them in my project also but none of them worked for me.

Enable user interaction for your imageview by below line

imgview.userInteractionEnabled =YES;

//Here is sample code

UILongPressGestureRecognizer *gestureRecognizer = [[UILongPressGestureRecognizer alloc] init];
[gestureRecognizer addTarget:self action:@selector(imgLongPressed:)];
gestureRecognizer.delegate = self;
imgview.userInteractionEnabled =YES;
[imgview addGestureRecognizer: gestureRecognizer];

- (void) imgLongPressed:(UILongPressGestureRecognizer*)sender
{
    UIImageView *view_ =(UIImageView*) sender.view;
    CGPoint point = [sender locationInView:view_.superview];

    if (sender.state == UIGestureRecognizerStateBegan)
    {

    }
    else if (sender.state == UIGestureRecognizerStateChanged)
    {

    }
    else if (sender.state == UIGestureRecognizerStateEnded)
    {

    }

}
