how to skin an iPad app

im new to ipad/开发者_运维知识库iphone development. what are some ways to skin an ipad app? (eg: the notes app that came with the iPad) Is there any tutorials or code samples?

I think the question has to do with skinning your own apps instead of skinning Apple's pre-existing apps. Assuming this:

Any buttons can be easily skinned with images. Just add the image to your XCode project. Then, select the button in Interface Builder and in the attributes inspector you can choose the image there.

You can skin other views by adding UIImageView's that cover the whole view and then moving them into the background of the layout.

My app Rith uses all of the standard controls, but everything is skinned.
