Signature in UIView

Question

I am looking for a class that will allow the user to draw?(the main purpose is to get their signature).

I checked Cocoa Controls but couldn't find such a class. Just want to now if there's any before I start writing it myself. Thanks

To get a JPG or PNG file, you can use the functions UIImageJPEGRepresentation or UIImagePNGRepresentation. They take a UIImage as input. And to get a UIImage from a UIView, you can use something like this.

UIGraphicsBeginImageContext(view.frame.size);
[view.layer renderInContext:UIGraphicsGetCurrentContext()]; 
UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
