title: xCode 5: I'm getting a small translucent square on UIButton selection
body: <p>If this is an Interface Builder issue, the solution has eluded me for days. I'm getting this weird translucent square on my UIButtons when they are selected, and I have no idea how to get rid of it. The buttons are not custom, they are "system" style buttons, and they are just simple rectangles.</p>
