| Objective-C use of pointers When do you and when dont you need the * symbol (which is because in objective-c all variables like NSString are pointer variables)? For example when do you need to do "NSString *" instead of just "NSString"? | |

In Objective-C, all object references are pointers, so you always need the pointer operator when you declare with an Objective-C object. For other types, the use is exactly the same as in C. Use pointers when you want to pass data structures or primitive types by reference. |
