Question

I am doing some custom drawing a UITableViewCell that I have subclassed. In there there is an OpenGL ES 2.0 control that needs user interaction to work… now if I start dragging horizontally the control responds but as soon as I go in the vertical direction then it starts to move the table view’s viewport. How do I stop this interaction from going to the UITableView and limit it to my own UIView in the UITableViewCell?

You can try to subclass UITableView and override following methods

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {  
    UITouch *touch = [touches anyObject];

    // if user tapped on your custom view, disable scroll        
        self.scrollEnabled = NO;
    // end if

    [super touchesBegan:touches withEvent:event];
}

- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event {
    self.scrollEnabled = YES;
    [super touchesEnded:touches withEvent:event];
}

- (void)touchesCancelled:(NSSet *)touches withEvent:(UIEvent *)event {
    self.scrollEnabled = YES;   
    [super touchesCancelled:touches withEvent:event];
}
