Frage
I'm using this code to render an image from view. Then i am saving it to photo album. The image is blurry? Why? Is there a solution?
UIGraphicsBeginImageContext(self.view.bounds.size);
[self.view.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *viewImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
Tnx all.
Lösung
You are propably using a retina device, Change the following
UIGraphicsBeginImageContext(self.view.bounds.size)
to
UIGraphicsBeginImageContextWithOptions(self.view.bounds.size, self.view.opaque, 0.0);
