在push出的viewcontroller里面下面方法不会被执行

- (BOOL)shouldAutorotate
{
    return YES;
}

- (NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskLandscapeLeft;
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
    return UIInterfaceOrientationLandscapeLeft;
}

怪我咯

我之前是这么做的：
添加UITabBarController、UINavigationController的分类

UITabBarController (xxx)

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

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

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

UINavigationController (xxx)

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

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

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