具有多个参数的功能 [英] function with multiple arguments

问题描述

如何在Objective-C的单个函数中传递多个参数?我想传递2个整数值，并且返回值也是整数.我想使用新的Objective-C语法，而不是旧的C/C ++语法.

how to pass multiple arguments in a single function in Objective-C? I want to pass 2 integer values and the return value is also integer. I want to use the new Objective-C syntax, not the old C/C++ syntax.

推荐答案

在Objective-C中，这真的非常容易.这是您在C语言中执行的方法:

In objective-c it is really super easy. Here is the way you would do it in C:

int functName(int arg1, int arg2) 
{
    // Do something crazy!
    return someInt;
}

由于它与C兼容，因此在Objective-C中仍然可以使用，但是使用Objective-C的方法是:

This still works in objective-c because of it's compatibility with C, but the objective-c way to do it is:

// Somewhere in your method declarations:
- (int)methodName:(int)arg1 withArg2:(int)arg2
{
    // Do something crazy!
    return someInt;
}

// To pass those arguments to the method in your program somewhere:
[objectWithOurMethod methodName:int1 withArg2:int2];
