iPhone:Tabbar hides when pushing from TableView to UIViewController

I have four Tab bar items in a Tab bar which is being bottom of the view where i have the TableView. I am adding Tab bar and items programmatically (Refer below code) not through I.B. Click on first three Tab bar items, will show the data in the same TableView itself. But clicking on last Tab bar items will push to another UIViewcontroller and show the data there. The problem here is, when i push to the viewController when clicking on last Tab bar item, main "Tab bar" is getting removed.

Tab bar code:

UITabBar *tabBar = [[UITabBar alloc] initWithFrame:CGRectMake(0, 376, 320, 44)];
item1 = [[UITabBarItem alloc] initWithTitle:@"First Tab" image:[UIImage imageNamed:@"first.png"] tag:0];
item2 = [[UITabBarItem alloc] initWithTitle:@"Second Tab" image:[UIImage imageNamed:@"second.png"] tag:1];
item3 = [[UITabBarItem alloc] initWithTitle:@"Third Tab" image:[UIImage imageNamed:@"th开发者_开发百科ird.png"] tag:2];
item4 = [[UITabBarItem alloc] initWithTitle:@"Fourth Tab" image:[UIImage imageNamed:@"fourth.png"] tag:3];
item5 = [[UITabBarItem alloc] initWithTitle:@"Fifth Tab" image:[UIImage imageNamed:@"fifth.png"] tag:4];
NSArray *items = [NSArray arrayWithObjects: item1,item2,item3,item4, item5, nil];
[tabBar setItems:items animated:NO];
[tabBar setSelectedItem:item1];
tabBar.delegate=self;
[self.view addSubview:tabBar];

Push controller code clicking from last Tab bar item:

myViewController = [ [MyViewController alloc] initWithNibName:@"MyView" bundle:nil];
        myViewController.hidesBottomBarWhenPushed=NO;
        [[self navigationController] pushViewController:myViewController animated:NO];

I am not seeing bottom Tab bar when i push my current TableView to myViewController. I am seeing full screen view there. I want to see bottom Tab bar always when every tab item clicked. What might be the problem here? Could someone who come across this issue, please share your suggestion to me?

Thank you.

You are using the TabBar itself (as view) as the main view initially.

Use UITabBarController like this:

//tabBarController is defined in the interface (the .h file)
tabBarController = [[UITabBarController alloc]init];

firstViewController = [[UIViewController alloc] init];
UITabBarItem *item1 = [[[UITabBarItem alloc]initWithTitle:@"First" image:nil tag:1] autorelease];
[firstViewController setTabBarItem:item2];

secondViewController = [[SecondViewController alloc]init];
UITabBarItem *item2 = [[[UITabBarItem alloc]initWithTitle:@"Sec" image:nil tag:1] autorelease];
[secondViewController setTabBarItem:item2];

//init the tab bar controller populated with two view controllers
[tabBarController setViewControllers:[NSArray arrayWithObjects:firstViewController,secondViewController,nil] animated:NO];

[window addSubview:tabBarController.view];
