Passing array to another class - Objective C

Question

I manage to pass the following array from MessagesTableViewController.m to arraySelectedCategory in another class called MessageDetailViewController.m:

self.messageDetailViewController.arraySelectedCategory =
        [[NSMutableArray alloc] initWithObjects:@"Value 1",@"Value 2", @"Value 3", nil];

but how do I hand over an array stored in: NSMutableArray *categories;

self.messageDetailViewController.arraySelectedCategory = ?????

Thanks!

I take it that you want a copy of the categories array?

self.messageDetailViewController.arraySelectedCategory = [categories copy];

@Darko Yes. And if that's not what your're looking for, a simple self.messageDetailViewController.arraySelectedCategory = categories should do.

Thanks! It helped a lot. I am still new to Objective C.

You can use NSUserDefaults. The value can be used in whole program.
