UIScrolview Prioritize vertical and horizontal scrolling

Question

I've a scenario where I am using a list of views that scrolls horizontally, like pagination. And each view has tableviews which scrolls vertically. Now the issue is when I want to scroll vertically. It hardly allows me to do that. But vertically it's fine. Can I arrange this in a way that vertically scrolling should have higher priority than horizontal? But both should be accessible.

Answer 1

Well, you have an UIScrollView for horizontal scroll and couple of UITableViews inside as pages? I think your issue lays in the UIScrollView which intercepts vertical pan gesture. Try to disable vertical scrolling for your UIScrollView and it should help.

Answer 2

In iOS 5, UIScrollView exposes its UIPanGestureRecognizer.

Set your custom swipe’s delegate to self and make the gestureRecognizer a property or ivar, and make your class conform to the <UIGestureRecognizerDelegate> protocol.

Then, implement UIGestureRecognizerDelegate’s – gestureRecognizer:shouldRecognizeSimultaneouslyWithGestureRecognizer: like so:

-(BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer
{
    if ([gestureRecognizer isEqual:self.swipe] && [otherGestureRecognizer isEqual:self.scrollView.panGestureRecognizer])
      {
         return NO;
      }
     return YES; //default
 }
