Getting the contents of a UIView as a UIImage

In Cocoa, it's really easy to take the contents of an NSView and convert them to an NSImage using dataWithPDFInsideRect:. I needed to do the same task on the iPhone, so immediately looked for a comparable method. I didn't find one.

Thankfully, Google came to the rescue. Josh Goebel shows how to do it right here.

Note: To use this in your project, you'll have to link to the QuartzCore framework and also #import <QuartzCore/QuartzCore.h>
