    text
    copied!<p>i'm using device orientation notification in order to know if the device has been rotated so that i can perform a selector. here is the code i'm using:</p> <pre><code>- (void)awakeFromNib { isShowingLandscapeView = NO; [[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(orientationChanged:) name:UIDeviceOrientationDidChangeNotification object:nil]; } - (void)orientationChanged:(NSNotification *)notification { UIDeviceOrientation deviceOrientation = [UIDevice currentDevice].orientation; if (UIDeviceOrientationIsLandscape(deviceOrientation) &amp;&amp; !isShowingLandscapeView) { [[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:UIStatusBarAnimationFade]; [self performSegueWithIdentifier:@"landscape" sender:self]; isShowingLandscapeView = YES; } else if (UIDeviceOrientationIsPortrait(deviceOrientation) &amp;&amp; isShowingLandscapeView) { [[UIApplication sharedApplication] setStatusBarHidden:NO withAnimation:UIStatusBarAnimationFade]; [self dismissViewControllerAnimated:YES completion:nil]; isShowingLandscapeView = NO; } } </code></pre> <p>however, when i navigate to the other child views and rotate the device, the selector is performed although the above code are in a class that is independent from the classes that the other views have. so how can i stop that? i tried:</p> <pre><code>[[UIDevice currentDevice] endGeneratingDeviceOrientationNotifications]; </code></pre> <p>and it also didn't work. my app actually pop into another view in landscape mode when the device is rotated. so in the child views, the landscape view appears in i rotate the device. how can i fix that?</p>
