In objective c, when creating objects, why do we need to use *?

Question

In objective c, when creating objects, why do we need to use *? For example, we are creating

NSString *string =@"i ma string";

In the above code why do we need to use *string

Can anyone explain please?

Thanks in advance.

Why not read a C tutorial before going to Objective-C? This is trivial. — The Paramagnetic Croissant, Apr 13 '14 at 14:32

Objective-C mandates that you access objects via pointers, such that they're created on the heap and never on the stack

* means that it is pointer to object, not the actual object
