Detect when a UITextView has finished scrolling

Question

Hi All,

Is there a way to detect when a UITextView has finished scrolling? As a note, I allow the user to enable or disable paging.

Thanks.

UITextView is a subclass of UIScrollView, which has a UIScrollViewDelegate class for controlling behaviour related to scrolling. One of its methods is scrollViewDidEndDecelerating. You can make your view controller implement this protocol, set your UITextView's delegate property to the view controller, and then implement the scrollViewDidEndDecelerating method. When the method is called, the UITextView will have finished scrolling. e.g.:

in .h:

@interface MyViewController : UIViewController <UIScrollViewDelegate>

in .m:

- (void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView
{
    NSLog(@"Finished scrolling");
}
