推荐答案
虽然不推荐，但您可以创建一个 UIViewController 访问它的视图属性并将其设置为主视图的子视图main UIViewController 正在管理。它有效，我从来没有遇到过这个问题。
Although it's not recommended, you can create an instance of a UIViewController access it's view property and set it as a subview of the main view your main UIViewController is managing. It works, and I never experienced a problem with this.
这就是说，建议的方法是有一个 NSObject 子类充当您的子控制器，而不是使用 UIViewController ，因为它有特殊行为。
That said, the recommended way is to have a NSObject subclass to act as your sub-controller, and not use a UIViewController as it has special behavior.
