Question

Is function overloading possible in Objective C ?
Well,Most of the programmers says no,

But it looks like possible,
for example:

-(int)AddMethod:(int)X :(int)Y
{
    return X + Y;
}
-(int)AddMethod:(int)X
{
    return X;
}

to call 1st one write [self AddMethod :3];
to call last one write [self AddMethod: 3 :4];

Answer 1

Method overloading is not possible in Objective-C. However, your example actually will work because you have created two different methods with different selectors: -AddMethod:: and AddMethod:. There is a colon for each interleaved parameter. It’s normal to put some text in also e.g. -addMethodX:Y: but you don’t have to.
