function with multiple arguments

Question

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.

Answer 1

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;
}

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];

Best of luck!

Answer 2

Since this is still google-able and there are better solutions than the accepted answer; there's no need for the hideous withArg2 – just use colons:

Declaration:

@interface
-(void) setValues: (int)v1 : (int)v2;

Definition:

@implementation
-(void) setValues: (int)v1 : (int)v2 {
    //do something with v1 and v2
}
