[Objective-C] differences between iskindofclass and ismemberofclass

Iskindofclass: returns a Boolean value that indicates whether the caller is an instance of given class or an instance of any class that inherits from that class.

Ismemberofclass: returns a Boolean value that indicates whether the specified er is an instance of a given class.

Iskindofclass andThe differences between ismemberofclass are:We can use iskindofclass to determine whether an object is an instance of a class or an instance of the class's ancestor class.
Ismemberofclass can only be used to determine the former and cannot be used to determine the latter.

It can be said that ismemberofclass cannot detect that any class is based on the fact of the nsobject class, And iskindofclass can.
