iOS Make an image file out of a UIImageView

[spaceman816]

Is it possible to create an image file (jpeg, etc.) out of a UIImageView that consists of a user-inputted drawing (CGContext) for emailing or other use?

You can use UIImageJPEGRepresentation().

Thanks
I couldn't find anything on this because I wasn't sure what to search for.

Why Apple decided to make it a function instead of a method (category) on UIImage is beyond me. Probably some intern implemented it 😉

I would suspect that it's technically part of Core Graphics (I haven't actually checked). It's pure C/all functions...
