ios Sprite Kit screengrab?

You almost have it, but the problem is as explained in the comment above. If you want to capture SKScene contents, try something like this instead:

UIGraphicsBeginImageContextWithOptions(self.view.bounds.size, NO, scale);[self.view drawViewHierarchyInRect:self.bounds afterScreenUpdates:YES];UIImage *viewImage = UIGraphicsGetImageFromCurrentImageContext();UIGraphicsEndImageContext();

The solution is to basically use the new method drawViewHierarchyInRect:afterScreenUpdates instead, which is the best we have for now; note, it's not exactly speedy, so doing this in realtime will not be pretty.

As a faster alternative, you can use the textureFromNode method on SKView, which returns an image of the view as an SKTexture. Simply pass the SKScene as the argument:

let texture = skView.textureFromNode(scene)

Or to capture part of the scene:

let texture = skView.textureFromNode(scene, crop: cropRect)

//1: get texture from "someNode"

let texture = skView.textureFromNode(someNode)

//2: get UIImage from the node texture

let image = UIImage(cgImage: texture!.cgImage())
