RemoveAllObjects equivalent fror NSArray

I know how I would achieve this using NSMutableArray, but whats the correct way of emptying a whole array of class NSArray. I need to do this because I need to reload a tableView. Im using ARC.

NSArray *yourArray  = [ whatever objects you have ]

//to empty this array
yourArray = [NSArray array];

NSArray is an immutable (unchangeable) class so there is no way to remove elements from the array. Basically, you will have to throw the array away and replace it with a new NSArray. Alternatively, you could just use an NSMutableArray.

You cant empty a non mutable NSArray, the best approach is to get a mutable copy of your array:

NSMutableArray *arr=[yourArr mutableCopy];
[arr removeAllObjects];

NSArray is an immutable type. You cannot alter it's contents after creation.

Either use an NSMutableArray or replace it with a new (empty) NSArray.
