在標籤之間切換時強制改變方向。 （目標c）

Question

所以我測試這個，所以我可以用它在我的大項目上。 我有一個名爲TabBar的tabbarcontroller 此TabBar有2個選項卡每個選項卡都有一個navigationcontroller。一個帶按鈕的視圖控制器（OkButtonViewController），當你點擊這個按鈕時，你會用標籤（LabelViewController）轉到視圖控制器。 OkButton視圖控制器始終處於縱向狀態，labelViewController可以切換方向。這隻在一種情況下才有效。當你在LabelViewController中定位橫向，並且切換選項卡時，OkButtonViewController也處於橫向模式，並保持橫向。我如何強制viewcontroll回到肖像？

這是我的代碼。

我可能需要在的TabBar或RotatingTabBarAppDelegate補充一下。我只是不知道是什麼。

TabBar.m

#import "TabBar.h" 

    @implementation TabBar 

    - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation 
    { 
     return [self.selectedViewController shouldAutorotateToInterfaceOrientation:interfaceOrientation]; 
    } 

    @end

     tab2.tabBarItem = [[UITabBarItem alloc] initWithTabBarSystemItem:UITabBarSystemItemSearch tag:1]; 
     TabBar *tbc = [[TabBar alloc] init]; 

     [tbc setViewControllers:[NSArray arrayWithObjects:tab1, tab2, nil]]; 

     [window addSubview:tbc.view]; 

     [window makeKeyAndVisible]; 


    }

    }

    } 

    - (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender { 
     if ([segue.identifier isEqualToString:kDetailSegue]) { 
      ((LabelViewController *)segue.destinationViewController).testTekst = sender; 
     } 
    } 

    @end

    @synthesize testLabel; 

    - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation 
    { 
     return YES; 
    } 

    -(void)viewWillAppear:(BOOL)animated 
    { 
     [super viewWillAppear:animated]; 
     self.testLabel.text = testTekst; 
    } 

    @end 

遺憾的英語不好。

你不能強迫一個視圖旋轉，或許蘋果會拒絕你的應用程序，你需要找到另一種方式來設計這個。
