You can implement same function in both viewcontrollers with the implementation of protocol. 您可以通过协议的实现在两个视图控制器中实现相同的功能。 And you can get reference of one viewcontroller in other view controller by using class level method which will return instance of that view controller. 通过使用类级别的方法，您可以获取另一个视图控制器中一个视图控制器的引用，该方法将返回该视图控制器的实例。
