If you want to uniquely name instances then instead of an array how about using a NSDictionary? Then you can grab the array of keys from it. Run through this key array to get the name of a particular instance and then use that key to get the actual object instance from the dictionary.

You're confusing objects and variables. Variables have names; objects don't unless you give them some name instance variable. More to the point, the same variable can reference different objects at different times. Given some collection of objects collection:

NSMutableArray *array = [NSMutableArray array];

for (id item in collection) {
    [array addObject:item];
}

This will create a mutable array with all the objects in collection, with the item variable pointing to a different object from collection on each iteration of the loop.
