I just found that there’s no LinkedList implementation in Objective-C, but I need one. So I am going to use std::list(or there’s a better alternative?).
My question is: what should I care about memory management under ARC and non-ARC?
You should manually take care of the memory management, since std::list is a C++ container. Or you can use
NSMutableArrayand treat it like a linked list, append new elements withinsertObject:atIndex:for the last index, iterate through it with an iterator,removeLastObject, etc.
