Basic Navigation between views not working

I'm having some trouble with basic navigation between views. I have a tabBarController with two views. In the first view controller, when the method that responds to a button press is called the self.navigationController is null. The debugger steps through the code but the screen in the simulator does not change. I have the following code in my viewController button response method:

FooViewController *fvc = [[FooViewController alloc] initWithNibName:@"FooViewController" bundle:nil];
[self.navigationController pushViewController:fvc animated=YES];

In the didFinishLaunchWithOptions method of my MyAppDelegate.m implementation I am creating a UINavigationController and initialising it with an instance of a UIViewController as the Root View Controller with the following code:

UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController: viewController1];
self.tabBarController = [[UITabBarController alloc] init];
self.tabBarController.viewControllers = [NSArray arrayWithObjects: viewController1, viewController2, nil];
self.window.rootViewController = self.tabBarController;

My current understanding is that the initWithRootViewController variable should bind the UINavigationController object to viewController1. What am I doing wrong?!? Any thoughts, suggestions or pearls of wisdom would be greatly appreciated.

Many thanks,



Yes initWithRootViewController does bind the navigation, but then in the Tab Bar you should set the UINavigationController and not the ViewController itself

Change this line

self.tabBarController.viewControllers = [NSArray arrayWithObjects: viewController1, viewController2, nil];


self.tabBarController.viewControllers = [NSArray arrayWithObjects: nav, viewController2, nil];

Also you appear to have a typo here

[self.navigationController pushViewController:fvc animated=YES];

change it to

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