How to detect what class a parameter is from

I have two classes, Class A and Class B. They can both call the same method in a controller. The method they call takes in a CGPoint. Is there any way I can determine which class the argument came from?

I have tried using the following:

if ([point isKindOfClass:[_territoryPaths class]])
{
    NSMutableDictionary *territoryPaths = [_territoryPaths territoryPaths];
}

if ([piont class] == [_territoryPaths class])
{
    NSMutableDictionary *territoryPaths = [_territoryPaths territoryPaths];
}

point is the CGPoint that the method takes in.

The best way to deal with this situation if you want to use this method in a class that is not ClassA or ClassB would be to modify your method so that it accepts a sender and do the isKindOfClass on the sender value.

For example:

- (void)someMethod:(id)sender withPoint:(CGPoint)point
{
    if ([sender isKindOfClass:[ClassA class]])
    {
        // Do class A stuff
    }
    else if ([sender isKindOfClass:[ClassB class]])
    {
        // Do class B stuff
    }
    else
    {
        // Unknown class
    }
}
