Question

touchesBegan: doesn’t work in UIScrollView. How do I enable touchesBegan: in UIScrollView?

Answer 1

You have to subclass UIScrollView to allow interception of the touch events.

For example, you could create a “special” UISCrollView like this:

@interface TouchableScrollView : UIScrollView {

}
@end

.m file:

@implementation TouchableScrollView

- (void) touchesEnded: (NSSet *) touches withEvent: (UIEvent *) event {

    if (!self.dragging) {
        [self.nextResponder touchesEnded: touches withEvent:event]; 
    }       

    [super touchesEnded: touches withEvent: event];
}

@end

This example only overrides touchesEnded, but you can do the same for touchesBegan
