Drawing in a UITextView

I'm trying to make a UITextView look like a piece of paper with the red lines, margins, etc.

I haven't found anything that would allow me to use graphics in a UITextView and I can't use a UITextField because I need to allow multiple lines...

I've 开发者_如何学编程tried drawing in a normal UIView and then trying to blend that with the UITextView but that apparently wasn't the right approach.

Any help would be great. Thanks!

Do you just need a background image? This thread may help:
