iOS - Disable UITabbarItem from AppDelegate

I want to disable and enable later an UITabbarItem from the AppDelegate.m. (To be specific, on didFinishLaunchingWithOptions should it be disabled and after a NSURLConnection it should be enabled. I already tried creating a external method in the First View Controller and calling it from the Delegate, but it do not work. Here is my attempt:

FirstViewController.m:

-(void)enableDataTab {

[[[[self.tabBarController tabBar] items] objectAtIndex:1] setEnabled:YES];

}

AppDelegate.m:

    homeVC = [[FirstViewController alloc] init];
    [homeVC disableDataTab];

Like this (in the view controller):

self.tabBarItem.enabled = NO;

Or like this (in the app delegate):

myFirstViewController.tabBarItem.enabled = NO;

The tab bar item representing a view controller is a property of that view controller.

Also, don't say 

homeVC = [[FirstViewController alloc] init];

That makes a whole new FirstViewController. You don't want a new FirstViewController; you want the one that's already there as a child of the tab bar controller.
