Is there a nine-patch loader for iPhone?

Question

Android has a nice way of defining stretchable images called a nine-patch. See these docs for a description of the concept. The idea is to surround a png image with a 1-pi

Answer 1

Also look at UIView's contentStretch property. It is more robust and well-behaved than stretchableImageWithLeftCapWidth. Basically, it works by just defining the stretchable rectangle within your image and automatically creating a scaled nine-patch. This internal rectangle can be anything - it doesn't even have to be in the center of the image. Plus unlike stretchableImage this method will properly shrink graphics and behave as expected for graphics with lighting or gloss. I can't think of any real-world application where you would want more than this.
