How can I get touch event for UIScrollView.I have a UIViewController and I placed a scrollView in viewController.I need to add imageViews to scrollView and if a particular image is clicked it should redirect to its corresponding viewController.
I knew how to add touch event to a UIViewController.But that doesn't work for a scrollView.

```
-(void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
{
    UITouch *touch= [touches anyObject];
    if ([touch view] == img1)
    {

        ViewController2 *viewController2=[[ViewController2 alloc]initWithNibName:@"ViewController2" bundle:nil];
        [self presentViewController: viewController2 animated:YES completion:nil];

    }
}

```

HOw can I get touches event for a scrollView ?
