objective c - iPhone SDK: How do I pass an array of values from a ViewController onto other ViewController?

Question

I tried creating a method like below in SecondViewController:

-(void)setValue:(NSMutableArray*)array
 { 
      //NSMutableArray *newArray = [[NSMutableArray alloc] init];
      newArray = [array retain];
 }

and passing the value from FirstViewController using an object of SecondViewController named second:

[second setValue:existingArray];

existingArray is an NSMutableArray.

What could be wrong?

Answer 1

In the code you have set the array in the "second" object of a SecondViewController.

So you need to use that object for displaying the SecondeViewController, other wise how can it won't show the array.

Check the following code.

 //   In the FirstViewController

- (void)buttonClicked:(id)sender{

    SecondViewController *second = [[SecondViewController alloc] initWithNibName:@"SecondViewController" bundle: nil];
 [second setValue:existingArray];
 [self.navigationController pushViewController:second animated:YES];
 [second release];

}

Here in the code I am assigning the data to the array in the "second" object and I am using that object to display the controller.
