In iOS, how to drag down to dismiss a modal?

Question

A common way to dismiss a modal is to swipe down - How do we allows the user to drag the modal down, if it\'s far enough, the modal\'s dismissed, otherwise it animates back

Answer 1

You can use a UIPanGestureRecognizer to detect the user's drag and move the modal view with it. If the ending position is far enough down, the view can be dismissed, or otherwise animated back to its original position.
