How to use one array in different classes?

Question

I have an array. It is filled in one class named "SampleDataDAO".

What i need:

In the 2nd class named "MainMenu" i need to keep this code:

- (void)viewDidLoad
{
[super viewDidLoad];
daoDS = [[SampleDataDAO alloc] init];
self.ds = daoDS.PopulateDataSource;
}

And in the third class named "HView" i need to use array "ds" (NSMutableArray). But i need to use it already filled from 2nd class, to return the count of elements:

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
// Return the number of rows in the section.
return ds.count;
}

Thanks for helping!

You can have that array declared and initialised in AppDelegate. Make that array as a property there. — Puneet Sharma

Why should not you have a singleton class, and have that array as a member of that singleton class.

Rather than using singletons, or getting a reference to the array from your appDelegate (which is just the same as using a singleton). A better way would be to pass the array as a reference to the view controller when you create it.

This is similar to the way that you pass a managed object context to view controllers if you are using Core Data, rather than calling down to the app delegate to get it.

Why don't u try to use constant file for this type or requirement.

Use these files for your requirement.

Constant.h
Constant.m

Import Constant.h file in your viewController and use that methods to set and get array directly with class name as

NSArray *array=[Constant getArray];

Or

[Constant setArray:array];
