Why does my programmatically created screenshot look so bad on iOS 7?

Question

I am trying to implement sharing app with facebook. I used this code to take the screenshot:

CGSize imageSize = CGSizeMake(self.view.bounds.size.width, self.         


        

Answer 1

On iOS7 you can have glitches if you use

[view drawViewHierarchyInRect:view.bounds afterScreenUpdates:YES]

during ongoing animation. Set afterScreenUpdates = NO to get rid of glitches.
