Access self.navigationController in a pushed ViewController

[coding]

Hello,

I've got a problem, which I can't figure out with the docs.

I got a class, named CustomViewController, which subclasses UIViewController.

In AppDelegate I got a property customNavController, which is connected to a TabBarController from MainWindow.xib. I created an object from class CustomViewController (which comes from CustomViewController.xib) and push it on the customNavController. It appears and works fine, but I need to send the navigationController property inside the CustomViewController object to an instance object. The problem is, inside the the method initWithNibName:bundle: of the CustomViewController, the navigationController property is nil. Also in viewDidLoad: (which is called before initWithNibName:bundle:, which I also don't understand) it is not valid (0x0). Can someone explain me this?

Code in AppDelegate:

CustomViewController *customViewController = [[[CustomViewController alloc] initWithNibName:@"CustomViewController" bundle:nil] autorelease];

[customNavController initWithRootViewController:customViewController];

Please help, I have done a lot of recherche work already with no result.

Thanks in advance.

kind regards, Phil

It makes perfect sense that your custom view controller has no reference to the nav controller in 'initWithNibName'. That's the first line of code you posted and at that point the view controller has not been associated with the nav controller at all.

'viewDidLoad' will get called as part of 'initWithNibName' to indicate that the view was actually loaded. But your still at that first line of code at this point.

At this point you associate the view controller with the nav controller. The view controller will now have its 'navigationController' property set. The view controller's 'viewWillAppear' and 'viewDidAppear' will be called at this time as it is being displayed.

Right, I got it. Simple thing if I think about it now.

Big thanks for your help.
