如何在Interface Builder中更改UIButton的背景图像并保持其形状？

Question

I'm in the process of writing my first Hello World application for iOS, and I don't know even elementary things, so I'm sorry if this question will be stupid. I want to change the background image of button. But when I do this button changes its shape and becomes squared instead of Rect Square (with non-zero corner radius). So the question are there some ways to change background and preserve button's shape either directly by Interface Builder or by manipulating XML-like language in .xib files or whatever other way.

Answer 1

Add a button and set its type property to custom. With this method you could define an image for the button as you would like it to be displayed not just the background within the rounded rect.
