如何在present出來的viewController裏使用push方法

   

MenuViewController * menuViewController = [[MenuViewController alloc] init];

    menuViewController.delegate = self;

    UIViewController * controller = self.view.window.rootViewController;

    controller.modalPresentationStyle = UIModalPresentationCurrentContext;

    menuViewController.view.backgroundColor = [UIColor clearColor];

    menuViewController.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;

    UINavigationController * jackNavigationController = [[UINavigationController alloc] initWithRootViewController:menuViewController];

imageNamed:@"navigationBar_bg.png"] forBarMetrics:UIBarMetricsDefault];

    [self presentViewController:jackNavigationController animated:YES completion:^{

     }];

這樣你就能夠在present出來的viewController裏暢通使用push方法退出其餘界面了。

對了，

UIViewController * controller = self.view.window.rootViewController;

    controller.modalPresentationStyle = UIModalPresentationCurrentContext;

這兩句是在第二個UIViewController中能夠設置alph看到第一個UIViewController的界面；也就是第一個UIViewController做爲背景了，，，
