Screenshot Using UIGraphicsBeginImageContextWithOptions For iPad 3 (Retina)

Question

I am taking a screenshot using the following code: ``` // Returns 1024x768 for iPad Retina CGSize screenDimensions = [[UIScreen mainScreen] bounds].size; // Create a graphics context with the target size // (last parameter takes scale into account) UIGraphicsBeginImageContextWithOptions(screenDimensions, NO, 0); // Render the view to a new context CGContextRef context = UIGraphicsGetCurrentContext(); [myView.layer renderInContext:context]; // Save to Camera Roll UIImage *screenshot = UIGraphicsGetImageFromCurrentImageContext(); UIImageWriteToSavedPhotosAlbum(screenshot, self, nil, nil); UIGraphicsEndImageContext(); ``` This works, however I have a report from a user that this results in an image in the Camera Roll that is not at the iPad retina resolution. Rather it looks more like the iPad non-retina resolution. (I don't have an iPad 3 to test this on). Is there anything else that I am doing wrong?

Accepted Answer

So I finally got a hold of a physical iPad Retina, and the code that I posted originally works fine. The resulting image does appear to be at the full Retina resolution.
