UIDevice Orientation

Question

I have the following code in a method. When I run this in the simulator the debugger skips right over the code?? What am I missing?

if (([[UIDevice currentDevice] orientation] == UIDeviceOrientationLandscapeLeft) || 
        ([[UIDevice currentDevice] orientation] == UIDeviceOrientationLandscapeRight)) 
{       

} else {

}

Answer 1

The best way to determine interface orientation is to look at status bar orientation:

 UIInterfaceOrientation orientation = [[UIApplication sharedApplication] statusBarOrientation];

    if(orientation == UIInterfaceOrientationPortrait || 
       orientation == UIInterfaceOrientationPortraitUpsideDown) {

       //Portrait orientation

}

if(orientation == UIInterfaceOrientationLandscapeRight ||
   orientation == UIInterfaceOrientationLandscapeLeft) {

    //Landscape orientation

}

UIDevice class measures orientation based on accelerometer and if device lays flat, it won't return the correct orientation.

Answer 2

Note that there's a macro UIDeviceOrientationIsLandscape and UIDeviceOrientationIsPortrait, so instead of comparing it separately to LandscapeLeft and LandscapeRight you could just do it like this:

if (UIDeviceOrientationIsLandscape([UIDevice currentDevice].orientation))
{
}
