title: Supporting specific device orientation in a iOS library - one place change
body: <p>I have an application with multiple view controllers in it. I need to share the library for the same. My application only supports landscape mode. Do I need to implement the below method in all my view controllers to return only landscape mode or is there any once place change that I can do for my library. For independent app I know we can set it in the info.plist but that option is not here with library. Any suggestions?</p>
  
  <pre><code>- (BOOL)shouldAutorotate;
  - (NSUInteger)supportedInterfaceOrientations;
  </code></pre>
