Today, I found a very strange bug. I have a popup dialog view, there are 7 buttons on it. The touch area of last button seems get a offset on top. And there is a small area on middle of button seems can't get any touch event.
I give the screenshot, you will know what I mean. The green area is tocuhable, the red area is un-touchable.
Does anyone get the same problem?? I still can't figure out how this happend...
PS. I create all buttons by Interface Builder, not by programming code.
