UITouch - Event not responding

Question

I have the following piece of code that I'm expecting to run on a touch event:

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
    UITouch *touch;
    touch=[touches anyObject];
    CGPoint point=[touch locationInView:self.view];

    if (CGRectContainsPoint([billTotal frame],point))
    {
        [self pickerShow];
    }
}

Its not being executed, any ideas what I'm doing wrong?

Regards, Stephen

Answer 1

Did you enable touches on the view?

I believe UIImageView has user interaction disabled by default.

If you have a .xib file for the view you can enable touches in Interface Builder by selecting the view, pressing CMD + 1 and checking User Interaction Enabled

In code you can do it like this

myView.userInteractionEnabled = YES;
