    [self.navigationController pushViewController:TripDetailViewObjec animated:YES];

}

And self.navigationController=null any help please ?

Answer 1

The navigation will not occur,because there is no navigationController within the first Tab.For navigation to take place you need to embed navigation controller over your TableViewController.try the following to embed the navigationController within the firstTab's TableView

in appDelegate.m

 - (void)applicationDidFinishLaunching:(UIApplication *)application { 

    UINavigationController * firstNavigationController = [[UINavigationController alloc]initWithRootViewController:yourTableViewController];

    // temporarily just used one tab

//tabBarController should be already connected through NIB

    [tabBarController setViewControllers:[NSArray arrayWithObjects:firstNavigationController,nil]];

    self.window.rootViewController = tabBarController;
    }
