Question on iPhone Development Custom UI

开发者_如何学编程So on the App Store, what I'm seeing a lot is a custom UI that still looks like the native Apple ones, but is some how "spruced up" in look. How exactly would I create something like that, as in say a button that is a hexagon or something instead of a rounded rectangle?

Thanks,

• Draw any image you want, using your favorite art program.
• Don't forget to make pressed and "up" states.
• Create your button (in IB or code.)
• Make the button of type UIButtonTypeCustom (IB or code.)
• In IB, set the button's image to your image.
• Set the image separately for NORMAL and HIGHLIGHTED states (IB or code.)

Example in code:

[myButton setImage: myImage forState: UIControlStateNormal];

They are probably either subclass' of UIView/UIWhatever or images with a transparent UIButton over top of the image. Is there something specific you want to implement?

Some examples: Subclassing a UIView
