Text input box like the SMS app on the iPhone

Question

I am having a terrible time trying to get an input box like the one in the SMS app.

Can anyone offer some guidance on how to build one of these and make it look goo

You get to do this yourself. Luckily, the UITextField can notify you whenever its text changes using UITextFieldTextDidChangeNotification, and luckily NSString has methods (under the UIKit Additions) that let you get the height of the string given a certain width using boundingRectWithSize:options:attributes:context:, and luckily you can resize a UITextField yourself using frame.
