Text Color - iOS 8.1

First - awesome control. I'm switching my UIKit game over to SpriteKit and this control might be just what I was looking for so thanks!

I was trying to set the label text color and even the example won't change color - it stays white. However once I used this:
`[numberButton setTitleColor:[UIColor blueColor] forState:UIControlStateNormal];
`
the button text color worked.
