Question

I’m attempting to write a multiview app in iOS and really having a bit of a tough time… I’ve setup a new project and I’ve got a rootViewController being launched by the appDelegate. In turn, the rootViewController attempts to load and display my first content view, although I seem to have fallen into some kind of infinite loop, I’m hoping someone here may have a hunch as to why…

    -(void)viewDidLoad
{   
    // Load up new instance of view
    TopLevelViewController *topLevelController = 
    [[TopLevelViewController alloc] initWithNibName:@"TopLevelView" bundle:nil];

    // Hand off viewController reference to root controller
    self.topLevelViewController = topLevelController;

    // Display the view
    [self.view insertSubview:topLevelController.view atIndex:0];

    // Release viewController
    [topLevelController release];


    [super viewDidLoad];
}

Above is my rootViewController viewDidLoad: method, although every time it executes insertSubview, it seems to return to the top and perform the whole thing again. I’m a bit confused as I’ve based this code almost identically on a tutorial I followed and it ran beautifully…which leads me to think the problem must be elsewhere, although I couldn’t possibly think where.

Appreciate any insight!

Just realized I had never closed this after the recent interest.

As I remember, @Wolfgang Schreurs is exactly correct. For whatever reason, while experimenting with the code, I had topLevelViewController inherit from rootViewController.

Hopefully this helps anyone else who may run into the same issue.
