Arithmetic on two CGPoints with + or - operators

cgpoint, cocoa-touch, math, objective-c

Solution

And here's the "something" that @ipmcc suggested: C++ operator overloading. Warning: do not do this at home.

CGPoint operator+(const CGPoint &p1, const CGPoint &p2)
{
    CGPoint sum = { p1.x + p2.x, p1.y + p2.y };
    return sum;
}

Problem

In Objective-C I'm starting to work with `CGPoints` and when I need to add two of them the way I'm doing it is this: ``` CGPoint p1 = CGPointMake(3, 3); CGPoint p2 = CGPointMake(8, 8); CGPoint p3 = CGPointMake(p2.x-p1.x, p2.y-p1.y); ``` I would like to be able to just do: ``` CGPoint p3 = p2 - p1; ``` Is that possible?
