iOS 7 has been out there for a while now. One thing that I tried to do but unsuccessfully was to replicate the Buy button Apple built into their App Store application.
The buttons have 1 pixel borders and invert the colors when highlighted or selected.
I could make the borders but couldn't make the inverted colors effect programmatically without any images.
I searched the Internet, but could not find anything useful so far.
Does anyone know how to make this kind of effect for UIButton on iOS 7?
Thanks in advance
