I have a UIButton subclass that I have set an image to in IB, and strangely about 1/3 of the button won't respond to touch! What's going on?

As described, I have a UIButton subclass, that I am designing in IB. I have set the button subclass to a UIView, and set an image to the button as well. I have set a UILabel beneath the image, attempting to give it the Finder look. Everything works great, except for the fact that the right 1/3rd of the image won't respond to touch!

It is the strangest thing. The button bounds are开发者_如何学Go set to encapsulate the entire image, but that right 1/3rd won'r respond.

Has anyone seen this before? Does anybody know what's going on?

Thanks
