Determine UIInterfaceOrientation on iPad

Question

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.

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:

-(void)viewDidLoad {
    [super viewDidLoad];
    //currentOrientation is declared as UIInterfaceOrientation currentOrientation
    currentOrientation = [[UIApplication sharedApplication] statusBarOrientation];
NSLog(@"%@",currentOrientation);  // == NULL
}

I need to determine the value of the interfaceOrientation and program conditionally. Thanks for your help!

Answer 1

Are you aware of the interfaceOrientation property of the UIViewController class?

- (void) viewDidLoad {
    [super viewDidLoad];
    BOOL isPortrait = UIDeviceOrientationIsPortrait(self.interfaceOrientation);
    // now do whatever you need
}

Or are you after [[UIDevice currentDevice] orientation]?

Answer 2

Especially at launch I have found the following to be always accurate for the UI, regardless of what the UIDevice says the orientation is.

[UIApplication sharedApplication].statusBarOrientation
