Are there any ordered containers such as C++ STL map, set in Objective-C, or am I supposed to reinvent the wheel?

NSArray is an ordered container. If you’re looking for an ordered map, no, it doesn’t have that. A common solution is to use a normal NSDictionary and track ordering with either an array (if the ordering is arbitrary) or an NSSortDescriptor (if the ordering is based on something intrinsic to the objects).
