In my program, I have a UIButton declared programmatically as a property of a UIVIewController. I have set it up to send actions when the user triggers the touchUpInside event, as shown here:
[restartButton addTarget:self action:@selector(handleRestart) forControlEvents:UIControlEventTouchUpInside];
where restartButton is the name of the UIButton.
When I enter UIControlEventTouchDown in the forControlEvents parameter, it works fine. However, UIControlEventTouchUpInside simply does not work. Does anybody know why this is?
You may want to check the restartButton.bounds. You may simply have it set to a size of zero causing UIControlEventTouchUpInside never to occur. Best way of checking for it is to add borders to layer.
[restartButton.layer setBorderWidth:1.0f];
[restartButton.layer setBorderColor:[UIColor redColor].CGColor];
Don't forget to #import <QuartzCore/QuartzCore.h> for above to work
