Question

I want to load a tabBarController with no tabBar selected. Actually each tabBarItem corresponds to a certain ViewController.But I have a view “Success” and it doesnot belong to any tabBarItem.So when Successview appears then I need a tabBarController with three tabBarItems (Search,Settings) need to appear and when any tabbaritem is then selected then corresponding ViewController should appear and SuccesView should disappear.
Gone through google and find out this but couldn’t make it working.

In SuccessView.m

- (void)viewDidLoad
{
    [super viewDidLoad];

// UIlabels and UITextFields loads

SuccessView *defaultView = [[SuccessView alloc]initWithNibName:@"SuccessView" bundle:[NSBundle mainBundle]];
    [self.tabBarController setSelectedViewController:nil];
    [self.tabBarController setSelectedViewController:defaultView];

    SearchView *first = [[SearchView alloc] initWithNibName:@"SearchView" bundle:nil];
    first.title=@"Search";

    Settings *second=[[Settings alloc]initWithNibName:@"Settings" bundle:nil];
    second.title=@"Settings";

    NSArray *viewArray= [NSArray arrayWithObjects:first,second, nil];

    tabbarController=[[UITabBarController alloc] init];
    [tabbarController setViewControllers:viewArray animated:NO];

    [self presentModalViewController:tabbarController animated:NO];
}

But I dont find any tabbarController added to SuccessView.Where I m going wrong?

Even i had the same situation i used UITabbar and tabbar items instead of UITabBarController because UITabBarController expects a current view from any of the tabbar items placed… Here’s the code..This should get you going:)

 UITabBar *tabBar = [[UITabBar alloc] initWithFrame:CGRectMake(your frame)];   
  NSMutableArray  *tabBarItemsArray= [[NSMutableArray alloc] init];
    UITabBarItem *tabBarItem1 = [[UITabBarItem alloc] initWithTitle:@"artist" image:[UIImage imageNamed:@"artist-tab.png"] tag:1];//assigning the title name and image

    [tabBarItem1 setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:[UIColor colorWithRed:48.0/255.0  green:60.0/255.0 blue:109.0/255.0 alpha:1.0],UITextAttributeTextColor,nil] forState:UIControlStateNormal];//set the color when the tabbar appears

    [tabBarItem1 setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:[UIColor whiteColor],UITextAttributeTextColor,nil] forState:UIControlStateSelected];//sets the color when the tabbar is selected

     UITabBarItem *tabBarItem2 = [[UITabBarItem alloc] initWithTitle:@"Facebook" image:[UIImage imageNamed:@"music-tab.png"] tag:2];

    [tabBarItem2 setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:[UIColor colorWithRed:48.0/255.0  green:60.0/255.0 blue:109.0/255.0 alpha:1.0],UITextAttributeTextColor,nil] forState:UIControlStateNormal];

    [tabBarItem2 setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:[UIColor whiteColor],UITextAttributeTextColor,nil] forState:UIControlStateSelected];

            [tabBarItemsArray addObject:tabBarItem1];
            [tabBarItemsArray addObject:tabBarItem2];
            tabBar.items = tabBarItemsArray;
            tabBar.delegate = self;

         [self.view addSubview:tabBar];

Make sure you add the delegate UITabBarDelegate in your header file to implement this method

   - (void)tabBar:(UITabBar *)tabBar didSelectItem:(UITabBarItem *)item{
        NSLog(@"Tabbar selected itm %d",item.tag); 
   // here you can call your view based on tab click you can try using switch statements here based on item.tag
       }

Hope this answers your question and helps:)

Also,we can customize the UITabbar with an image…do let me know..i will post the code in here if you want.
