  // [self.report makeKeyAndVisible];

    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.

Use below code:

     self.tabBarController.viewControllers = [NSArray arrayWithObjects:nav1,nav2,nav3,nav4,nav5,nil]];
     self.window.rootViewController = self.tabBarController;

UPDATE:

also for Hide and Show the UITabBar then use bellow code ..

just put this methods in AppDelegate.m file and when you want to hide tabbar at that time just create AppDelegate object and call bellow hideTabBar method

- (void) hideTabBar:(UITabBarController *) tabbarcontroller {

    int height = 480;

    [UIView beginAnimations:nil context:NULL];
    [UIView setAnimationDuration:0.3];

    for(UIView *view in tabbarcontroller.view.subviews) {
        if([view isKindOfClass:[UITabBar class]]) {
            [view setFrame:CGRectMake(view.frame.origin.x, height, view.frame.size.width, view.frame.size.height)];
        } 
        else {
            [view setFrame:CGRectMake(view.frame.origin.x,view.frame.origin.y, 320, 436)];
        }
    }
    [UIView commitAnimations];
}

- (void) showTabBar:(UITabBarController *) tabbarcontroller {

    int height = 436;

    [UIView beginAnimations:nil context:NULL];
    [UIView setAnimationDuration:0.3]; 

    for(UIView *view in tabbarcontroller.view.subviews) {

        if([view isKindOfClass:[UITabBar class]]) {
            [view setFrame:CGRectMake(view.frame.origin.x, height, view.frame.size.width, view.frame.size.height)];            
        } 
        else {
            [view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, height)];
        }
    }    

    [UIView commitAnimations];
}

If you want to add UITabBarController programmatically, then you need to add your tabbarcontroller to your ViewController. you need to use this line,

[self.view addSubview:self.tabBarController.view];
