iOS storyboard passing data navigationViewController
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...}
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...}
