updating table view with data in array?

I am creating a Ipad with two view controllers. One view controller is FirstViewController and the other is SecondViewController. In FirstViewController, I fill an array with numbers. Now in my SecondViewCOntroller, I have a table view. I want to put the array that I created in FirstViewController into my SecondViewController table view? How do I do this? Please help me!

The most straight forward approach will be to create a property on SecondViewController.h like:

@property (nonatomic, retain) NSMutableArray *yourArray;

and in SecondViewController.m, put:

@synthesize yourArray;

At this point you have created a property on SecondViewController. Now, when you are about to open Second View Controller, just create its instance and do something like following:

secondViewController.yourArray = array;
[self.navigationController pushViewController:secondViewController];

This approach breaks MVC. You can't have data array as an instance variable in your FirstViewController. You'd have to store data in some other class (the M part of MVC). You fill that M part from FirstViewController (the V part) and then access that filled M part from SecondViewController. This way you won't be dependent on how those two controllers relate to each other (parent/child or siblings or whatever other hierarchy you may think of).

The most simple approach I can think of is storing serialized array in a plist file. Storing the file in first and accessing it in the second view controller.

You need to reference the NSArray object in the SecondViewController, you could do this by means of a delegate. A delegate is an instance variable that contains the pointer to the delegate, in this case the FirstviewController. Then in FirstViewController you add a property for the NSArray if its an instance variable, and call delegate.someArrayName in the secondviewController
