`iSmovingToparentViewController`/`iSmovingToparent`错误true
在我的视图控制器中，我正在检查iSmovingToparent viewwillappear ，这样我才能在首次显示视图控制器并且不是时才能执行一些逻辑。当后来的视图控制器从堆栈中弹出以揭示我的原始控制器时。
我希望此值是true，当VC首次推到导航堆栈和false时出现时，由于后来的VC弹出了堆栈。
但是，在这两种情况下，该值最终都是true。有什么原因会发生这种情况？
In my view controller, I am checking for isMovingToParent inside viewWillAppear so that I can execute some logic only when the view controller is first displayed and not when a later view controller is popped off the stack to reveal my original one.
I would expect this value to be true when the VC is first pushed onto the navigation stack and false when it appears because of a later VC popping off the stack.
However, in both cases, the value ends up being true. Any reason why this would be happening?

您是否覆盖任何
didmove（toparent：）/willmove（toparent：）方法？如果是这样，请确保您正在调用超级的该方法的版本。如果您不这样做，则似乎错误地设置了iSmovingToparent一系列属性。注意：如果有人有证明上述行为的文档，请编辑答案:)
Are you overriding any of the
didMove(toParent:)/willMove(toParent:)methods? If so, make sure you are callingsuper's version of that method. If you fail to do so, theisMovingToParentseries of properties seemingly can be incorrectly set.Note: If anyone has documentation attesting to the above behaviour, please edit the answer :)
