How can we implement a common tabbar for all views in IOS? - ios

Question

I am new to IOS. In my app's home, there are 3 tabs and 4 buttons(using navigation controllers). I created a tabbarcontroller inside appdelegate.m as follows:
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Override point for customization after application launch.
//Initializing the view controllers
UIViewController *disController1 = [[DisController1 alloc]initWithNibName:#"DisController1" bundle:nil];
UIViewController *viewController = [[ViewController alloc] initWithNibName:#"ViewController" bundle:nil];
UIViewController *wishlistController = [[Wishlist alloc]initWithNibName:#"Wishlist" bundle:nil];
UIViewController *helpController = [[HelpController alloc]initWithNibName:#"HelpController" bundle:nil];
UIViewController *disController2 = [[DisController1 alloc]initWithNibName:#"DisController2" bundle:nil];
NSMutableArray *viewControllersArray = [[NSMutableArray alloc]init];
[viewControllersArray addObject:disController1];
[viewControllersArray addObject:viewController];
[viewControllersArray addObject:wishlistController];
[viewControllersArray addObject:helpController];
[viewControllersArray addObject:disController2];
//Initializing the tab bar controller
UIImage *img = [UIImage imageNamed:#"SES_tab bar"];
CGSize newSize = CGSizeMake(SCRN_WIDTH, TABHEIGHT);
Common *common = [[Common alloc]init];
UIImage *newImage = [common imageResize:img andResizeTo:newSize];
[common setTabBarColorandImage:newImage];
tabController = [[UITabBarController alloc]init];
tabController.viewControllers = [NSArray arrayWithObjects:disController1, viewController,wishlistController,helpController,disController2 ,nil];
tabController.selectedIndex = 1;
UITabBarItem *firstTab = [[tabController.tabBar items]objectAtIndex:0];
UITabBarItem *lastTab = [[tabController.tabBar items]objectAtIndex:4];
[firstTab setEnabled:NO];
[lastTab setEnabled:NO];
UINavigationController *navCtrl = [[UINavigationController alloc]initWithRootViewController:tabController];
//navCtrl.navigationBarHidden = NO;
//[navCtrl.navigationBar setBackgroundImage:img forBarMetrics:UIBarMetricsDefault];
[navCtrl.navigationBar setBarStyle:UIBarStyleBlackTranslucent ];
[navCtrl.navigationBar.topItem setTitle:#"Home"];
[self.window addSubview:tabController.view];
self.window.rootViewController = navCtrl;
[self.window makeKeyAndVisible];
return YES;
TabBar works fine for my home page.But my problem is when i clicks on a button, Tab bar doesn't appear in the new view. How can I implement that?

You should create UINavigationControllers for each of your tabs. Set each view controller in your current array as the root view controller of each of those navigation controllers.
EDIT:
UIViewController *disController1 = [[DisController1 alloc]initWithNibName:#"DisController1" bundle:nil];
UIViewController *viewController = [[ViewController alloc] initWithNibName:#"ViewController" bundle:nil];
UIViewController *wishlistController = [[Wishlist alloc]initWithNibName:#"Wishlist" bundle:nil];
UIViewController *helpController = [[HelpController alloc]initWithNibName:#"HelpController" bundle:nil];
UIViewController *disController2 = [[DisController1 alloc]initWithNibName:#"DisController2" bundle:nil];
UINavigationController *navController1 = [[UINavigationController alloc] initWithRootViewController:disController1];
//etc. for each of the view controllers that you have allocated.
NSMutableArray *viewControllersArray = [[NSMutableArray alloc]init];
[viewControllersArray addObject:navController1];
[viewControllersArray addObject:navController2];
[viewControllersArray addObject:navController3];
[viewControllersArray addObject:navController4];
[viewControllersArray addObject:navController5];
