    View2 *acc=[[View2 alloc]initWithNibName:@"View2" bundle:nil];

    UITabBarItem *item = [[UITabBarItem alloc] initWithTitle:@"Title" image:[UIImage  imageNamed:@"singleicon.png"] tag:0];
    UITabBarItem *item1 = [[UITabBarItem alloc] initWithTitle:@"Reports" image:[UIImage imageNamed:@"doubleicon.png"] tag:1];

    //[item1 setBadge:@"25"];
    self.tabBarController=[[UITabBarController alloc]init];
    [self.tabBarController setViewControllers:[NSArray arrayWithObjects:nav1,nav2,nav3,nav4,nav5,nil]];

    self.report = self.tabBarController;
  // [self.report makeKeyAndVisible];

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