我應該在ViewController中設置子視圖框架

我將方向設置爲RootViewController中左側的橫向，但是在viewDidLoad或viewWillAppear中，VC的視圖邊界不會旋轉。在viewDidAppear中，它有一個正確的框架。我認爲這不是一個好地方，我該怎麼做？我應該在ViewController中設置子視圖框架

@implementation RootViewController 


    - (void)viewDidLoad 
    { 
     [super viewDidLoad]; 
     CGRect frame = self.view.bounds; 
    } 

    - (void)viewWillAppear:(BOOL)animated 
    { 
     [super viewWillAppear:animated]; 
     CGRect frame = self.view.bounds; 

    } 

    - (void)viewDidAppear:(BOOL)animated 
    { 
     [super viewDidAppear:animated]; 
     CGRect frame = self.view.bounds; 
    } 

    #pragma mark - Orientation 

    - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation 
    { 
     return toInterfaceOrientation == UIInterfaceOrientationLandscapeLeft; 
    } 

    //for iOS 6 or later 

    - (BOOL)shouldAutorotate 
    { 
     return YES; 
    } 

    - (NSUInteger)supportedInterfaceOrientations 
    { 
     return UIInterfaceOrientationMaskLandscapeLeft; 
    } 

    @end

和日誌表明：

viewDidLoad,x = 0.000000, y = 0.000000,w = 300.000000 h = 480.000000 
    viewWillAppear:,x = 0.000000, y = 0.000000,w = 300.000000 h = 480.000000 
    viewDidAppear:,x = 0.000000, y = 0.000000,w = 480.000000 h = 300.000000

您可以設定方向變化後的幀：

-(void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation

我試過了，沒有調用此方法.. – DJean

我想應該是在這個函數

（vo ID）viewDidLayoutSubviews {}
