自动旋转不工作ios6.1

Question

自动旋转在ios6.1中不起作用。但下面的代码在其他应用程序中是有效的。

代码：

@implementation UINavigationController (RotationIn_IOS6)

-(BOOL)shouldAutorotate
{
    return [[self.viewControllers lastObject] shouldAutorotate];
}

-(NSUInteger)supportedInterfaceOrientations
{
    return [[self.viewControllers lastObject] supportedInterfaceOrientations];
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
    return [[self.viewControllers lastObject]  preferredInterfaceOrientationForPresentation];
}

@end


- (BOOL)shouldAutorotate
{
    //returns true if want to allow orientation change
    return TRUE;


}
- (NSUInteger)supportedInterfaceOrientations
{
    //decide number of origination tob supported by Viewcontroller.
    return UIInterfaceOrientationMaskAll;


}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
    //from here you Should try to Preferred orientation for ViewController

    return UIInterfaceOrientationLandscapeLeft | UIInterfaceOrientationLandscapeRight | UIInterfaceOrientationPortrait;
}

- (void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation)  interfaceOrientation duration:(NSTimeInterval)duration
{

}
