UIImage is a great class, but it has a lot of limitations.

Image resizing is one of them (the lack of). If your looking for a way to re-size UIImages, save your self the agony of copy/pasting the numerous code examples you’ll find through stackoverflow or whatever. I was shocked by the amount of people posting buggy code, for what is actually a relatively simple problem.

I do find it funny that people describe CoreGraphics or Quartz as low level APIs. For a primarily Objective-C coder maybe, but for anyone who has experience with C, it shouldn’t pose much of a burden. Sure CoreGraphics IS lower level than UIImage, but I’d still describe it as a fairly “high level” API, especially when you compare it to OpenGL.

Anyhow, if your looking to re-size UIImages easily, without having to use CoreGraphics or Quartz, I would strongly recommend checking out Trevor’s article over here:

He has written some UIImage categories which will save a lot of time, and more importantly they are well written (and work).

Since the new year Apple appears to be making massive improvements to their overall approval times. An update for F1 Insider was approved in about 48 – 72 hours, which we had previously planned for 1 – 2 weeks!

Very good job, I hope it continues.

Now we just need to get some consistency in the approval/rejection guidelines
