UIApplication setStatusBarOrientation
Sets the application's status bar to the specified orientation, optionally animating the transition.
- (void)setStatusBarOrientation:(UIInterfaceOrientation)interfaceOrientation animated:(BOOL)animated
Parameters
interfaceOrientation
A specific orientation of the status bar. See UIInterfaceOrientation for details. The default value is UIInterfaceOrientationPortrait.
animated
YES if the transition to the new orientation should be animated; NO if it should be immediate, without animation.
Discussion of [UIApplication setStatusBarOrientation]
Calling this method changes the value of the statusBarOrientation property and rotates the status bar, animating the transition if animated is YES . If your application has rotatable window content, however, you should not arbitrarily set status-bar orientation using this method. The status-bar orientation set by this method does not change if the device changes orientation.
UIApplication setStatusBarOrientation example.
//will rotate status bar
[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationLandscapeRight];
//will re-rotate view according to statusbar
UIViewController *c = [[UIViewController alloc]init];
[self presentModalViewController:c animated:NO];
[self dismissModalViewControllerAnimated:NO];
[c release];
[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationLandscapeRight];
//will re-rotate view according to statusbar
UIViewController *c = [[UIViewController alloc]init];
[self presentModalViewController:c animated:NO];
[self dismissModalViewControllerAnimated:NO];
[c release];
