UINavigationController方向

Question

I have UINavigationController with couple of view controller. this is the list of them: Main -> Album -> image

Now in the first and the second(Main and album) i want that the UINavigationController will not rotate(only portrait), and in the third one(Image) it will be possible to rotate.

i made already category for the UINavigationController:

-(BOOL)shouldAutorotate {
    if ([self.topViewController isKindOfClass:[MWPhotoBrowser class]]) {
        return YES;
    }
    return NO;
}

-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation {
    if ([self.topViewController isKindOfClass:[MWPhotoBrowser class]]) {
        return YES;
    }
    return NO;
}

- (NSUInteger)supportedInterfaceOrientations {
    return UIInterfaceOrientationMaskAll;
}

Now my problem is that when i push the image viewcontroller and the rotate the device (the viewcontroller rotate) and press back and here(Album) the viewcontroller is rotate to and can't rotate back to portrait.

By the way: i noticed it happen only in device with iOS 6 and iPhone 5

您是否尝试过包含以下方法，但为视图控制器返回正确的值？

- (NSUInteger)supportedInterfaceOrientations {

return UIInterfaceOrientationMaskPortraitUpsideDown;

}
