title: Errors when I put buttons very close to each other in Xcode
body: <p>In Mainstoryboard (I'm not sure if this also applies to earlier versions) I want to put two buttons very close to each other with one or two pixels separating them. Mainstoryboard allows this, but when I run it on the simulator, it puts one button partially on top of the other, even though they're supposed to be separated. I think this might have to do with the white border that appears around a button when you double-click it, but I can't find any way to change this border. Does anyone know what is going on?</p>
