I am working with a UINavigationController in my app. In viewDidLoad, the root view controller acquires information from the internet, parses it, and displays it.

When going to another view in the UINavigationController, and then going back to the root UIViewController, the information in the controller is not reloaded. This leads me to think that viewDidLoad is not being called.

What method should I use to ensure this information is reloaded when the root view controller is popped back to in the UINavigationController?

Edit:

Thanks for the quick responses guys, it means a lot. One more question regarding your answers: viewWillAppear or viewDidAppear? Are there pros/cons for each?

    You should process viewWillAppear: or viewDidAppear:, depending on whether you’d like a reload to happen before or after thew view shows up on the screen. viewDidLoad is called only once, when the view is loaded.
