I’m starting out Objective-C and I was wondering, why do we have to put asterisks in the method parameter type?
e.g.
- (void)myMethodThatTakesAString:(NSString*)string;
Thanks in advance!
The asterisk means that the parameter is a pointer to an NSString. You can’t pass an NSString to a method, but rather you pass a pointer to it.
Although you might get away with simply using pointers when you have objects and not really understanding them, it’s probably a good idea to prioritize learning about pointers.
