Question

I’m using an UIPageViewController in my application and I wanted to have a few UIButtons inside it, sort of like a menu. The problem I have is that when I put an UIButton (or any other interactive element) near the edges of the screen and tap it, instead of the UIButton action being applied, what happens is that the page changes (because the tap on the edge of the screen changes the page on the UIPageViewController). I’d like to know if there’s a way to make it so that the UIButton has higher priority than the UIPageViewController so that when I tap the button, it applies the appropriate action instead of changing the page.

I came here with the same problem. Split’s link has the answer.

Make your root view controller the delegate of each of the UIPageViewController’s gesture recognizers, then prevent touches from being delivered if they occur inside any UIControl:

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch
{
    return ([touch.view isKindOfClass:[UIControl class]] == NO);
}
