iphone - UIScrollView scroll detection -

I see a UIScrollView scroll in a UIViewController horizontally How can I find out that the scroll is in the middle or right or somewhere in the middle?

You probably will need to look at the scrollwiduleget method below.

ObjC

  - (zero) scrollViewDidScroll: (UIScrollView *) scrollview {nslog (@ "point:% @", nsstringframcppoint (scrollviewsoffference )); }  

Swift

  override func scrollViewDidScroll (scrollView: UIScrollView) {println (scrollView.contentOffset)}  Take a look at 

Additionally, your scrollview rep should be your_scroll_view.delegate = self; Be sure to set and your view controller should be consistent with & lt; UIScrollViewDelegate & gt;
