title: Determine UIInterfaceOrientation on iPad
body: <p>I don't need to specify the orientation in this case, I just need to detect it, but I'm having trouble.  I have conditional code that should only work in portrait, and if the device is in landscape I need to do something else.  Since the deviceOrientation is not necessarily the same as the interfaceOrientation, I can't come up with a way to test for portrait mode.</p>
  
  <p>Most tutorials I find on Google are ways to force landscape or do some sort of rotation.  The only thing I want to do is just determine what the orientation is.  Here is my code, which is not working:</p>
  
  <pre><code>-(void)viewDidLoad {
      [super viewDidLoad];
      //currentOrientation is declared as UIInterfaceOrientation currentOrientation
      currentOrientation = [[UIApplication sharedApplication] statusBarOrientation];
  NSLog(@"%@",currentOrientation);  // == NULL
  }
  </code></pre>
  
  <p>I need to determine the value of the interfaceOrientation and program conditionally.  Thanks for your help!</p>
