How to capture the contents of a UIView and change it into a UIImage?

Question

Hello,

I currently have a view and I would like to change it into a UIImage. I would like to do this because the UIImage class is much better for what I need to do. How would you capture the contents of a UIView and copy the contents into a UIImage?

Thanks,

-David

Answer 1

Here, try this

CGImageRef screen = UIGetScreenImage();
UIImage *screenImage = [UIImage imageWithCGImage:screen];

That will take a screenshot of the screen, so in theory capturing all of the view's elements and gives you a UIImage to work off of. Hope that helps!

Like this:

UIGraphicsBeginImageContext(myView.bounds.size);
[myView.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *myImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();

You will need to include the CoreGraphics framework, and import the CALayer.h:

#import <QuartzCore/CALayer.h>
