    copied!<p>This is an observation more than anything, because I appear to have found a work-around...</p> <p>The code below fails to work <em>when it's in a controller which has been pushed onto a UINavigationController stack</em>. In this situation <code>[UIDevice currentDevice].orientation</code> consistently returns <code>UIDeviceOrientationUnknown</code>. </p> <pre><code>-(void)layoutAccordingToOrientation { UIDeviceOrientation orientation = [UIDevice currentDevice].orientation; NSLog(@"layoutAccordingToOrientation/orientation==%i", orientation); if (UIInterfaceOrientationIsLandscape(orientation)) { : _detailToolbar.frame = CGRectMake(0, 660, 1024, 44); } else { : _detailToolbar.frame = CGRectMake(0, 916, 768, 44); } } -(void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration { [self layoutAccordingToOrientation]; } - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return YES; } </code></pre> <p>The following call <em>has</em> been made:</p> <pre><code>[[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications]; </code></pre> <p>To work around this <code>UIDeviceOrientationUnknown</code>-problem, I now use the following instead:</p> <pre><code>UIInterfaceOrientation orientation = [UIApplication sharedApplication].statusBarOrientation; if (UIInterfaceOrientationIsLandscape(orientation)) { etc. } else { etc. } </code></pre> <p>... which works every time.</p> <p>Still, I fail to see why the first variation would not work in the context of a pushed view controller. Ideas anyone? Is it simply a bug?</p>
