IOS, how to get device orientation at launch or viewDidAppear

I have an app that depending on the orientation shows different images... I have been using:

UIDeviceOrientationIsLandscape([[UIDevice currentDevice] orientation]);

To see if it is landsCape or not... but if I call this in my rootViewController: viewDidLoad,viewWillAppear, orviewDidAppear its always false.... then i was trying figure if its landsCape or no by comparing the width and height of a frame that has autosizeMask so it always is full screen... its a scroll view and I do the following:

BOOL landscape = self.frame.size.width>self.frame.size.height;

But that doesn't work either (always false) because the view still has the frame for the portrait view at that moment.

Solution

  • Instead of using device orientation, check for interface orientation. These macros will help you.

    #define IS_PORTRAIT     UIInterfaceOrientationIsPortrait([[UIApplication sharedApplication] statusBarOrientation])
#define IS_LANDSCAPE    UIInterfaceOrientationIsLandscape([[UIApplication sharedApplication] statusBarOrientation])
