Let User Crop Photo in iOS App [closed]

Question

There are several questions (and answers) concerning cropping of images/photos within an iPhone app.

But I couldn't find an answer covering the common task of giving the user a rectangle which can be resized with a pinch gesture to letting him resize the area to cut.

You can find this functionality in many apps (Instagram, Twitter, etc...) most likely to cut a user photo to the right proportions. So I guess there are many people with the same problem.

Does anyone have code or tutorials to show how this task can be done?
