You need to do this

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
    // Return YES for supported orientations;

return (interfaceOrientation == UIInterfaceOrientationLandscapeLeft) || (interfaceOrientation == UIInterfaceOrientationLandscapeRight);

}

First of all define in your Info.plist file following key-value pair:

UIInterfaceOrientation UIInterfaceOrientationLandscapeLeft

or UIInterfaceOrientationLandscapeRight or to define initial start in Landscape right orientation afterward define shouldAutorotateToInterfaceOrientation in all your controllers in following way:

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
  return UIInterfaceOrientationIsLandscape(interfaceOrientation);
}
