Question

I have the following array.

    NSArray *arrayDisplay = [[NSArray alloc] initWithObjects:@"Daily", 
        @"Weekly", @"Monthly", nil];

I need to use it in two views, I’m concerned that I may make changes and forget to change the other in the future. So I’d like to declare it once and reuse it.

How should I do this?

Answer 1

You can keep it as a property in a common object such as the application delegate.

Assuming its nonatomic,retain type property then access it like:

myAppDelegate *del = [[UIApplication sharedApplication] delegate];
del.arrayDisplay = [NSArray arrayWithObjects:@"Daily",@"Weekly", @"Monthly", nil];

Although if you plan on changing it you might want an NSMutableArray.
