I'm taking a picture of my screen and manipulating it by using UIGraphicsGetImageFromCurrentImageContext()
. Everything is working just fine. However, on an iPhone 4, the resolution looks pretty shabby as it seems like the image it uses is standard resolution, not @2x. Is there any way to increase the resolution of the resulting image?
UIGraphicsBeginImageContext(self.view.bounds.size);
[self.view.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
