UIDeviceOrientation ipad

Question

I have the following code to fill a view according to the orientation. This always returns landscape.

- (void)setData:(BCPlaylist *)list  {
UIDeviceOrientation orientation = [[UIDevice currentDevice] orientation];
    if (orientation == UIDeviceOrientationPortrait || orientation == UIDeviceOrientationPortraitUpsideDown){
      NSLog(@"portrait");
      [self setPlaylist:list];
      [self renderPlaylist];
      [activity stopAnimating];
    }else{
      NSLog(@"landscape");
      [self setPlaylist:list];
      [self renderPlaylistOne];
      [activity stopAnimating];
     }
}

I change views correctly in - (void)animateRotation:(UIInterfaceOrientation)interfaceOrientation duration:(NSTimeInterval)duration { But that doesn't work when already in landscape or portrait when changing a playlist.

Answer 1

Instead of using [[UIDevice currentDevice] orientation] for checking orientation use statusbar orientation to get the exact orientation.

    UIDeviceOrientation orientation = [UIApplication sharedApplication].statusBarOrientation;

Answer 2

To avoid a warning, use :

UIInterfaceOrientation orientation = [[UIApplication sharedApplication] statusBarOrientation];

Answer 3

You'd always get landscape, because that's your default (from your if statement). If you walk through the debugger with a breakpoint there, you'll see that the orientation reported is that of Unknown.

In fact, your code is fine, but this is a limitation of the simulator. If you take the same code, using Device orientation and not Interface orientation, you'll get actual values if you use it on the physical device, which can be driven by the if-statement you have.
