iOS SDK UITabBarController仅显示两个UIViewControllers之一

Question

I am trying to make an iPhone application with two tabs: One for the game, and one for the instructions.

However, when I add the UIViewControllers using

[_tabBarController setViewControllers:[NSArray arrayWithObjects:self.viewController, self.viewController2, nil] animated:NO] 

it only shows the first one.

I have tried simply setting the title property of each of my view controllers then adding them, I have tried doing

[_viewController setTabBarItem:[[UITabBarItem alloc] initWithTitle:@"something" image:nil tag:0]]

And also tried doing the previous operation in the initWithNibNamed: bundle: method.
However, nothing I do seems to allow me to show more than the one tab on the screen.
Any help is greatly appreciated.
Thanks,
Michael.

Answer 1

Is viewController2 nil and it just didn't load? Make sure you have it properly connected when using IB.
