CGImage (or UIImage) from a CALayer

Question

I have created a CALayer (I added several shapes to the layer, but ultimately, I have a single CALayer), and I am having a LOT of trouble adding it to a CGImage.

Answer 1

Try this...

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

Answer 2

Create a bitmap graphics context and use renderInContext: to draw the layer into it. You now have the layer in an image.
