Signature in UIView
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 i开发者_Go百科t myself. Thanks
Look at this tutorial: http://www.ifans.com/forums/showthread.php?t=132024
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();
