iOS storyboard passing data navigationViewController

Question

I have problem with proper passing data between view\'s but not in standard way.

Picture describing my problem:

Answer 1

Here it is in swift:

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) 
{    
    if (segue.identifier == "sLogowanieFirmy") {
        let nav = segue.destinationViewController as! UINavigationController 
        let firmyVC = nav.topViewController as! FirmyVC
        firmyVC.tabFirmy = self.tabFirmy            
    }

    // etc...
}

Answer 2

UINavigationController has a property called topViewController which returns the view controller that is at the top of the stack.

So your prepareForSegue: method may look something like this...

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    if ([[segue identifier] isEqualToString:@"sLogowanieFirmy"]) {
        UINavigationController *nav = [segue destinationViewController];
        FirmyVC *firmyVC = (FirmyVC *)nav.topViewController;
        firmyVC.tabFirmy = self.tabFirmy;
    }

    // etc...
}
