title: Scale UIView and all its children
body: <p>I have an UIView with around 50 UIButtons. All button positions were given in pixels, relative to the left upper corner of my main UIView.</p>
  
  <p>All (background) images used in the view are available in higher resolution. As I am porting my app from iPhone to iPad, I would like to increase the effective pixel size of the UIView.</p>
  
  <p>Now I'm searching a way to upscale the whole UIView by a factor of 2*. Is that possible without destroying the position of the inner elements?</p>
  
  <p>FYI, the UIView is designed in a NIB-file in XCode. But I don't mind if it can be done programmatically.</p>
