iPhone SDK isKindOfClass和isMemberOfClass之间的区别 [英] iPhone SDK difference between isKindOfClass and isMemberOfClass

问题描述

任何人都可以告诉我 isKindOfClass：（Class）aClass 和 isMemberOfClass：（Class）aClass 函数？
我知道它是一个小的东西，一个是全局的，而另一个是一个确切的类匹配，但我需要有人指定哪个是。

Can any one tell me what the difference is 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.

推荐答案

isMemberOfClass：如果接收者是指定类的实例，则返回YES。

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

大多数时候，你想使用 isKindOfClass：来确保你的代码也能用于子类。

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

NSObject协议参考更多地谈到这些方法。

The NSObject Protocol Reference talks a little more about these methods.
