I have a scrollview and I am looking at user input. I would like to know that his finger is currently on the X Plane. Is it possible through ScrollView and / or its representative or do I override the touch
, etc.?
I assume that you set up your scroll view representative if you have done so You only need to implement scrollViewDidScroll:
with the protocol ...
- (zero) scrollViewDidScroll: (UIScrollView *) scrollView {CGPoint TouchPoint = [scrollView. PanGestureRecognizer Location InView: scrollView]; NSLog (@ "Touch Point: (% F,% F)", TouchPoint.X, Touch Point.i); }
While the user is scrolling, this will be an update.
Additional information: Note that if you have something like UIPageControl
, then it's navigating between your scroll view, The situation can be calculated based on the number of pages (i.e. if each page is 100 pixels wide, page 0 will start from 0 point, one point on page 100 etc.).
