Improved Gradient Buttons

I've been playing around a bit, improving my imageless gradient button class. The new version allows you to specify the gradient for the normal and highlighted state by populating two arrays, one with the colors that make up the gradients and another with the relative location for each color. I've gotten rid of the abstract parent class and individual child classes and all the functionality is now contained in a single class.


There are five built-in styles which can be seen in the image above, or you can manually set the gradient to any value you'd like. You can download the source codes from the Google code page. There are no restrictions or limitations on its use.

The easiest way to use these is to add a UIButton instance to your view in Interface Builder, then change the underlying class from UIButton to GradientButton. Because there's no way to create IB palettes for iPhone classes, you'll also have to implement viewDidLoad and set the gradient or use the existing methods there.
