How to save a view as an image:

UIGraphicsBeginImageContext(myView.bounds.size);
[myView.layer renderInContext:UIGraphicsGetCurrentContext()];
viewImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();

It's covered in one of the first lectures in this term of Stanford's free iPhone programming course. There's a video and PDF notes.

Basically, you can create a UIImage and use its graphics context to draw into it, then save a PNG representation of the image.
