Beyond bounds for empty array

[spiderguy84]

I am trying to implement an inbox for rich notifications with xtify to my tab bar app. The code they use in example I adapted for my use to this:

- (UINavigationController *) setupPortraitUserInterface 
{
	UIWindow *localPortraitWindow;
	localPortraitWindow = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    self.portraitWindow = localPortraitWindow;
	
	
	[localPortraitWindow release];
	
    [portraitWindow setBackgroundColor:[UIColor whiteColor]];
    
	
	tabBarController = [[UITabBarController alloc] init];
    tabBarController.delegate = self;
	localViewControllersArray = [[NSMutableArray alloc] initWithCapacity:5];
	
   
	UIViewController *inboxVC=[[XLappMgr get ]getInboxViewController];
	UIImage* iImage = [UIImage imageNamed:@"inbox.png"];
	inboxVC.tabBarItem.image = iImage;
	
	inboxNavController = [[UINavigationController alloc] initWithRootViewController:inboxVC];
    
	[localViewControllersArray insertObject:inboxNavController atIndex:1]; 
    [localViewControllersArray insertObject:thirdView atIndex:2];
    [localViewControllersArray insertObject:firstView atIndex:0];
    [localViewControllersArray insertObject:fourthView atIndex:3];
    [localViewControllersArray insertObject:fifthView atIndex:4];

   firstView= [[FirstViewController alloc] init];
	thirdView= [[ThirdViewController alloc] init];
	fourthView= [[FourthViewController alloc] init];
	fifthView= [[FifthViewController alloc] init];

	
	tabBarController.viewControllers = localViewControllersArray;
	
	[localViewControllersArray release];
	

	[portraitWindow addSubview:tabBarController.view];
	

	[portraitWindow makeKeyAndVisible];
	
	return inboxNavController;
    
    
   	
}

I get the error

[__NSArrayM insertObject:atIndex:]: index 1 beyond bounds for empty array'

Why is the array empty?

Because you haven't added anything to it yet?

Instead of specifying an index, just add them in order like this:

[localViewControllersArray addObject:firstView];
[localViewControllersArray addObject:inboxNavController];
//etc..

	[localViewControllersArray addObject:inboxNavController]; 
        [localViewControllersArray addObject:firstView];
    [localViewControllersArray addObject:thirdView];
    [localViewControllersArray addObject:fourthView];
    [localViewControllersArray addObject:fifthView];

It now gives me the insertObject:atIndex cannot be set to nil. Nowhere in the whole file does it even have the code for insertObject:atIndex.

Try cleaning, deleting the app, and rebuilding.

Same Issue

'*** -[__NSArrayM insertObject:atIndex:]: object cannot be nil'

You need to allocate your controllers before you add them to the array.

You need to initialize firstView,thirdView, fourthView, fifthView before you add them to the array.

[firstView= [[FirstViewController alloc] init];
thirdView= [[ThirdViewController alloc] init];
fourthView= [[FourthViewController alloc] init];
fifthView= [[FifthViewController alloc] init];
inboxNavController = [[UINavigationController alloc] initWithRootViewController:inboxVC];
    
[localViewControllersArray addObject:inboxNavController]; 
[localViewControllersArray addObject:firstView];
[localViewControllersArray addObject:thirdView];
[localViewControllersArray addObject:fourthView];
[localViewControllersArray addObject:fifthView];

[firstView= [[FirstViewController alloc] init];
thirdView= [[ThirdViewController alloc] init];

inboxNavController = [[UINavigationController alloc] initWithRootViewController:inboxVC];
    
[localViewControllersArray addObject:inboxNavController]; 
[localViewControllersArray addObject:firstView];
[localViewControllersArray addObject:thirdView];
[localViewControllersArray addObject:fourthView];
[localViewControllersArray addObject:fifthView];

Thanks to you both, that did it

Well, I thought that fixed the problem. The app will run without terminating or giving errors, but it is just one big white screen, no tab bar controller or anything else.
