Answer 1

You'll want to use UIGraphicsBeginImageContext() to generate a CGContextRef, then use UIGraphicsGetCurrentContext() to get a reference to it. Now draw your current images into the context. When you're done, use UIGraphicsGetImageFromCurrentContext() to generate an UIImage from that context, and UIGraphicsEndImageContext() to clean up.

See Apple's UIKit Function Reference doc.
