You should still call the base implementation in case an intermediate class in the inheritance has implemented this method.
如果继承中的中间类已实现了此方法，则仍应调用基实现。
Because an intermediate class in the inheritance might implement this method, we recommend that you call the base implementation in your implementation.
由于继承中的中间类可能会实现此方法，因此我们建议您在实现中调用基实现。
