What is the difference b/w NSArray
and NSMutableArray
?
NSMutableArray
(and all other classes with Mutable
in the name) can be modified. So, if you create a plain NSArray
, you cannot change its contents later (without recreating it). But if you create an NSMutableArray
, you can change it — you'll notice it has methods like -addObject:
and -insertObject:atIndex:
.
See the documentation for details.
