Question

I added a UIPanGestureRecognizerto my UIButton. And now my when I drag a short distance with my finger after I pressed the button, the button stops being highlighted. Normally, a UIButton will stay highlighted unless you drag pretty far outside the UIButtons frame. However, with a pan gesture recognizer, now even if I drag a little bit, the button stops being highlighted.

Nothing in my code sets the buttons highlighted property to no. I even tried erasing all the code in my panning gesture recognizers action selector thing(the method that gets called whenever i pan on my button).

I also tried setting the button’s highlighted property to NO in the panning gesture recognizer’s action selector thing.

This kind of worked its just the highlightedness flashes. When you pan the highlighted goes away then comes back really fast, like a flash. So, this doesnt work too. Any ideas?

Gestures, by default, will cancel the touches in the views that they are linked to. So, when the touches in your button get cancelled it becomes unhighlighted. To prevent this behavior, set the cancelsTouchesInView property of your gesture to NO.
