How can I programmatically link an UIView or UIImageView with an event like "touch up inside"?
- by Thanks
Interface Builder will only allow me to hook up such events for an button. But like in HTML, I just want to haven an blank UIImageView where - as soon as the user taps it - a method is invoked. I hope there is some cool programmatically way of doing that, which I don't know about.
UPDATE:
In my View Controller that creates the UIImageView I tried to do this:
SEL actionSelector = @selector(doSomethingWhenImageIsTouched:);
[self.myUIImageView addTarget:nil action:actionSelector forControlEvents:UIControlEventTouchUpInside];
The compiler gives me a warning, that UIImageView may not respond to addTarget:... what do I have to do so that it works with an UIImageView. I see in the docs that UIImageView does not inherit from UIControl, but addTarget: is part of UIControl.
UPDATE:
I ended up creating an UIButton after creating the UIImageView. Then I set the frame of that button to the frame of the UIImageView, and alpha to 0.1f. For some reason, it will not work if alpha is 0.0f. And then, I did that cool addTarget: thing...
