Question

我已禁用xib的autolayout。但我正面临这个问题。即使我没有以编程方式添加任何子视图，并且我在此视图中有3个元素：

1。 UIImageView 2. UIButton 3. UIButton。

过去3天我受苦，但我无法找出错误。所以请任何人帮助我。我们将非常感谢您的帮助。

    That view's superview: NO SUPERVIEW

Answer 1

是的，我找到了解决方案。原因是：没有设置 UIViewControllerWrapperView 的框架所以我做了这个

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

    self.tabBarController.view.superview.frame = self.view.bounds;
}
