Question

when I’m trying to call a method on an object of type id, i get a warning raised (method not found). Of course not, but isn’t that the sense of an id object?

Is there a way to tell the compiler:
“You don’t now the class of the object on which i am calling this method, but don’t worry, i’m sure it does implement it!” ?

Answer 1

You could use performSelector?

And if you’ve got an object type id it’s probably a good idea to use respondsToSelector as well 🙂

i.e.

if ([myObject respondsToSelector:@selector(dosomething:)])
    myObject performSelector:@selector(doSomething:) withObject:@"hello"];
