ios - 父 View 在关闭模态视图 Controller 后更改其框架

Question

我有两个 View Controller 。当我在“A” View Controller 中模态显示“B” View Controller 然后关闭它时，“A” View Controller 中的 View 将其框架从 {{0, 0}, {320, 480}} 更改为 {{0,0 }, {0,0}}。所有 subview 不改变其位置但不响应。

Controller “A”代码:

- (void)viewDidLoad {
    [super viewDidLoad];
    self.view.translatesAutoresizingMaskIntoConstraints = NO;
    self.logoImageView.translatesAutoresizingMaskIntoConstraints = NO;
    self.view.backgroundColor = WHITE_C;
    buttonHeight = self.view.frame.size.height/5;
    buttonYPosition = self.view.frame.size.height - buttonHeight;
    buttonW = self.view.frame.size.width/2;
    [self configureButtons];
}

- (void) viewWillAppear:(BOOL)animated {
    [super viewWillAppear:animated];
}

- (void) viewDidAppear:(BOOL)animated {
    [super viewDidAppear:animated];
}

- (void) auth {
    [self performSegueWithIdentifier:segueToAuth sender:self];
}

Controller “B”代码:

- (void)viewDidLoad {
    [super viewDidLoad];
    self.navigationController.navigationBar.barTintColor = ORANGE_C;

    UIImage * backArrow = [UIImage imageNamed:@"back_orange.png"];
    UIBarButtonItem * back = [[UIBarButtonItem alloc] initWithImage:backArrow style:UIBarButtonItemStylePlain target:self action:@selector(backToWelcomeScreen)];
    [self.navigationItem setLeftBarButtonItems:@[back]];
}

#pragma mark - Buttons

- (void) backToWelcomeScreen {
    [self dismissViewControllerAnimated:YES completion:nil];
}

有人知道为什么会这样吗？

我尝试通过 viewDidAppear: 设置框架，但没有任何反应。

问题出在:

self.view.translatesAutoresizingMaskIntoConstraints = NO;
self.logoImageView.translatesAutoresizingMaskIntoConstraints = NO;

删除应用程序后效果很好。
