Answer 1

You have to add that tabbarItem in UITabBar.

   NSArray *items = [[NSArray alloc]init];
    [items addObject:self.tabBarItem]; //add all your tabBarItems in an array
    [tab setItems:items animated:YES]; //then set all your tabBarItems in UITabBar like this

Actually you are using same instance of tabBarItem thats'y you are getting only second button. Do this way, and Please if this helps you then accept the answer.

UITabBar *tabBar = [[UITabBar alloc]initWithFrame:CGRectMake(0, 725, 768, 49)];
    NSMutableArray *items = [[NSMutableArray alloc]init];
    UITabBarItem *item1 = [[UITabBarItem alloc]initWithTitle:@"first" image:nil tag:1];
    UITabBarItem *item2 = [[UITabBarItem alloc]initWithTitle:@"second" image:nil tag:2];
    UITabBarItem *item3 = [[UITabBarItem alloc]initWithTitle:@"third" image:nil tag:3];
    UITabBarItem *item4 = [[UITabBarItem alloc]initWithTitle:@"fourth" image:nil tag:4];

    [items addObject:item1];
    [items addObject:item2];
    [items addObject:item3];
    [items addObject:item4];

    [tabBar setItems:items];
    [self.view addSubview:tabBar];

Answer 3

Dont navigate the view controllers, because then your controller which contains the TabBar will get popped out.

When we use UITabBar we dont use navigation in this way.

Just addSubView the new controllers with such frame so that your TabBar will alwaz be visible.

Answer 5

That's not the way you do to create and add a TabBar programmatically. You'd rather use this other method: https://stackoverflow.com/a/3844365/655221
