iOS在isKindOfClass和isMemberOfClass之间的区别 [英] iOS difference between isKindOfClass and isMemberOfClass

问题描述

isKindOfClass:(Class)aClass和isMemberOfClass:(Class)aClass函数之间有什么区别? 我知道这有点小，一个是全局的，另一个是完全匹配的类，但是我需要有人指定哪个是哪个.

What is the difference between the isKindOfClass:(Class)aClass and the isMemberOfClass:(Class)aClass functions? I know it is something small like, one is global while the other is an exact class match but I need someone to specify which is which please.

在Swift isKind(of aClass: AnyClass)和isMember(of aClass: AnyClass)中.

推荐答案

isKindOfClass:返回YES从指定类继承的任何类的实例.

isKindOfClass: returns YES if the receiver is an instance of the specified class or an instance of any class that inherits from the specified class.

isMemberOfClass:仅在接收者是指定类的实例的情况下返回YES.

isMemberOfClass: returns YES if, and only if, the receiver is an instance of the specified class.

大多数时候您想使用isKindOfClass:来确保您的代码也可用于子类.

Most of the time you want to use isKindOfClass: to ensure that your code also works with subclasses.

NSObject协议参考详细讨论这些方法.
