macOS Methods with objects

[diogosgp]

Hi guys, my doubt is when I know that I have to use a method like this:

[myCombo addItemsWithObjectValues:myArray];

or

myArray = [NSMutableArray arrayWithObjects: object1, object2, object3, nil];

The first example I used the name of the object + the method.
The second example I used the name of the class + the method.
I know that the first one I'm not adding to the value but how I'm gonna know which one to use?

Cheers

You know based on whether the method is documented with a leading - for instance methods called on an object or a + for class methods called on the class.
