Segue from TableViewController to another TableViewController

Using storyboards I have a table view controller with a list of rows. When a row is selected, I want to pass the data associated with that row across to another table view controller which is embedded within an UINavigationController.

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {

    if ([segue.identifier isEqualToString:@"EditJob"])
    {
        NewJobsTableViewController *newJobsTableViewController = segue.destinationViewController;
        NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow];

        Jobs *job = [self.fetchedResultsController objectAtIndexPath:indexPath];
        newJobsTableViewController.jobDetails = job;

    }
}

On the last line within the prepareForSegue method I am getting the following error:
[UINavigationController setJobDetails:]: unrecognized selector sent to instance 0x83a7780 2012-11-11 08:50:25.335 My Trades[40612:c07] * Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UINavigationController setJobDetails:]: unrecognized selector sent to instance 0x83a7780'

jobDetails is declared in the newJobsTableViewController as:

@interface NewJobsTableViewController : UITableViewController <UITextFieldDelegate,      NSFetchedResultsControllerDelegate> {
    Jobs *_jobDetails;
}

@property (strong, nonatomic) Jobs *jobDetails;

I am not sure why it's causing this error.

It sounds to me like you set up your storyboard wrong. That second tableViewController shouldn't be embedded in its own navigation controller. Just set up a push segue from your first tableViewController to the second -- the second will automatically be embedded in the same navigation controller as the first one.

The reason for the error, I think, is because the destination view controller is actually the navigation controller that you embedded the second view controller in. This line doesn't do what you expect it to do:

 NewJobsTableViewController *newJobsTableViewController = segue.destinationViewController;

Even though you're setting the return value of destinationViewController to your class, it will return whatever it actually is -- I'm betting that if you log the class of newJobsTableViewController, it will actually come back as UINavigationController.
