drawRect function is never called when compiled with XCode5....
Any help on this would be appreciated. For some reason, the drawRect function is never being called, and hence the text field is never drawn.
Well, found the cause. The control's width is being set to zero. When I force it back, it displays correctly....but unsure why it's being set to width zero, and only on iOS7. This control is on a storyboard.
Also, when the picker is actually displayed, the width is again reset to zero.
Ended up having something to do with changes to AutoLayout. I had to add constraints for height and width of the fields so they wouldn't auto-resize.
Sorry I didn't get to you sooner - just saw this. I've found auto layout to be pretty pesky. I'll add a blurb to the readme about this if your problem is resolved. Have you had any other issues? I haven't gotten around to testing it on iOS 7.
