Repositioning controls when the orientation changes

Question

I know Auto Layout can be used to make the sizes and position consistent when the orientation changes. Is it possible to completely change the layout when the orientation change

Answer 1

When using autolayout you can override updateViewConstraints to modify the layout on orientation change:

- (void)updateViewConstraints{

  [super updateViewConstraints];
  //portrait
  if(UIInterfaceOrientationIsPortrait(self.interfaceOrientation)){

  }
  //landscape
  else{
    //
  }
}
