How to programatically take a screenshot in Sprite-Kit? - ios

Question

I've been reading resolved questions on how to programmatically take a screenshot but I can't seem to get what I've read to work in sprite kit. For instance:
This question How to take a screenshot programmatically
UIGraphicsBeginImageContext(self.window.bounds.size);
[self.window.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
NSData * data = UIImagePNGRepresentation(image);
[data writeToFile:#"foo.png" atomically:YES];
UPDATE April 2011: for retina display, change the first line into this:
if ([[UIScreen mainScreen] respondsToSelector:#selector(scale)])
UIGraphicsBeginImageContextWithOptions(self.window.bounds.size, NO, [UIScreen mainScreen].scale);
else
UIGraphicsBeginImageContext(self.window.bounds.size);
gave me this information, which I tested on my game but it didn't work because window was not recognized on an SKScene. I tried replacing it with scene but that didn't work. Any suggestions?
I also tried this:
UIGraphicsBeginImageContextWithOptions(self.view.bounds.size, NO, scale);
[self drawViewHierarchyInRect:self.bounds afterScreenUpdates:YES];
UIImage *viewImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
Which I found in this question: ios Sprite Kit screengrab?
But it didn't seem to work either because it didn't recognize scale, or bounds in the second line.

This is the best solution to take a screen shoot in your Sprite-Kit
UIGraphicsBeginImageContextWithOptions(self.view.bounds.size, NO, 1);
[self.view drawViewHierarchyInRect:self.view.bounds afterScreenUpdates:YES];
UIImage *viewImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
return viewImage;

Answer 2

func screenShot() {
UIGraphicsBeginImageContextWithOptions(UIScreen.mainScreen().bounds.size, false, 0)
self.view!.drawViewHierarchyInRect(self.view!.bounds, afterScreenUpdates: true)
var image:UIImage = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()
var Image = image //The image is stored in the variable Image
}
screenshot() //Calls the function and takes a screenshot

Answer 3

// Full Screen Shot function. Hope this will work well in spritekit.
func screenShot() -> UIImage {
UIGraphicsBeginImageContext(CGSizeMake(frame.size.width, frame.size.height))
var context:CGContextRef = UIGraphicsGetCurrentContext()
self.view?.drawViewHierarchyInRect(frame, afterScreenUpdates: true)
var screenShot = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext();
return screenShot
}

Answer 4

you can take screen shot for a any view.UIGraphicsBeginImageContextWithOptions(self.view.bounds.size, self.view.opaque, 0.0);
[self.view.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *gameOverScreenImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
