我应该在ViewController中设置子视图帧

Question

我将方向设置为RootViewController中剩余的横向，但在viewDidLoad或viewWillAppear中，VC的视图边界不是旋转的。在viewDidAppear中，它有一个正确的框架。我不认为它在viewDidAppear中是个好地方，我该怎么办？

    @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        

日志显示：

    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

Answer 1

您可以在方向更改后设置框架：

-(void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation

Answer 2

我认为它应该在这个功能中

  

  
• （void）viewDidLayoutSubviews {}
