IOS: merge ImageView and UIImage

Question

I want put over an UIImage a small UIImageView and I want as result an UIImage, what can I do?

The UIImageView has an associated UIImage, so what you really want is to “merge” two UIImages. Now what do you mean by “merging”? Simply painting one over the other? — zoul

You have to create a new graphics context (UIGraphicsBeginImageContextWithOptions()), then draw the two images into the context (-[UIImage drawInRect:]), and then retrieve an image from the context (UIGraphicsGetImageFromCurrentImageContext()).

Don't forget to call UIGraphicsEndImageContext() at the end.

No, I won't. I pretty much listed every single call that you need above. With the help of the documentation, you should be able to figure out the rest pretty easily.

blackguardian, at least try yourself first and ask then for assistance if you have a problem.
