我可以在Objective-C中重载运算符吗? [英] Can I overload an operator in Objective-C?

问题描述

是否可以在Objective-C中覆盖运算符?

Is it possible to override operator use in Objective-C?

例如

myClassInstance + myClassInstance

调用自定义函数以将两者相加.

calls a custom function to add the two.

推荐答案

运算符重载不是Objective-C的功能.如果可以将您的类的两个实例一起添加，请提供一个方法，并允许使用该方法添加它们:

Operator overloading is not a feature of Objective-C. If two instances of your classes can be added together, provide a method and allow them to be added using that method:

Thing *result = [thingOne thingByAddingThing:thingTwo];

或者，如果您的班级可变:

Or, if your class is mutable:

[thingOne addThing:thingTwo];
