How Do I detect the orientation of the device on iOS?

by

Really old thread, but no real solution.

I Had the same problem, but found out that getting The UIDeviceOrientation isn’t always consistent, so instead use this:

UIInterfaceOrientation orientation = [UIApplication sharedApplication].statusBarOrientation;

if(orientation == 0) //Default orientation 
    //UI is in Default (Portrait) -- this is really a just a failsafe. 
else if(orientation == UIInterfaceOrientationPortrait)
    //Do something if the orientation is in Portrait
else if(orientation == UIInterfaceOrientationLandscapeLeft)
    // Do something if Left
else if(orientation == UIInterfaceOrientationLandscapeRight)
    //Do something if right
