I have a problem like in this question, but answers don't help me. I want that colors navigation bar in seconds screen will be like a first screen. iOS 9 or later.

Need your advice for adding separator in between icons for tabbar.
Let me explain my application first. I have six view controller
MenuViewController
FirstViewController
SecondViewController
ThirdViewController
FourthViewController
FifthViewController
All these 6 ViewControllers are in navigationController. I want to show my "MenuViewController" first at the starting time of the app, after splash screen, which contains 5 buttons (For :FirstViewController, SecondViewController, ThirdViewController, FourthViewController, FifthViewController). In this viewController there will be no TabBarController at the bottom of the page. But other viewController will be in tabbarController. When i touch one of those five button in menuviewController, it will bring me to that corresponding view controller where i can find the tabbarController at the bottom. I can do it with custom coding, positioning and setting image behind them. Here is the code:
AppDelegate.h :
#interface AppDelegate : UIResponder <UIApplicationDelegate, UITabBarControllerDelegate>

I use this code for every "IBAction" with different index :
For example : "FirstViewController" with "index: 0"
- (IBAction)GotoFirstViewController:(id)sender
{
AppDelegate *appdelegte = (AppDelegate*)[[UIApplication sharedApplication] delegate];
[[[appdelegte navigationController] view]removeFromSuperview];
[[appdelegte window] addSubview:[[appdelegte tabBarController] view]];
[[appdelegte tabBarController] setSelectedIndex:0];
}
Now the problem is after going to a ViewController, and come back to "MenuViewController"
Useing this code :
-(IBAction)goBack:(id)sender
{
menuViewController = [[MenuViewController alloc] initWithNibName:#"MenuViewController" bundle:nil];
[self.navigationController pushViewController:menuViewController animated:YES];
}
I cannot go to another ViewController (any of five) pressing the same button.
If any one know, when the tabbar is setup from "seceondViewController (Here : firstViewController)" then after coming to the "firstViewController ( here : menuViewController)" from other ViewController, how to go again in the other ViewController which are connected with tabbar, please share with me.
Thanks a lot for reading this post and a lot thanks in advance.

Based on apple documentation UITabBar is a subclass of UIViewController and can be a child View..! But it must be the UIWindow rootController if not your app will crash!!! I had the same problem at the end I had to use UIToolBar to do the same thing.. though with a very hard work on customization.
I am not much familiar with iPad app SplitViewController. I have used the SplitViewController in my app. When change the orientation from portrait to landscape, Masterview is hiding from splitView. Could you please any help me to sort out this issue.
I have attached my source for your reference.
Creating SplitViewController:
self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
// Override point for customization after application launch.

UINavigationController *masterNavigationController = [[UINavigationController alloc] initWithRootViewController:menuViewController] ;

UINavigationController *detailNavigationController = [[UINavigationController alloc] initWithRootViewController:detailViewController] ;

I have created a UITabbar with 3 items and placed it on a UIScrollView
When I click the buttons of the tabbar they do not respond in the bottom half.
The upper area is working fine.
When clicking in the area just above the tabbar the tabs are also switched.
What can be wrong?
How can i correct this misalignment of the clickable button area?
In viewDidLoad:
[super viewDidLoad];
scroll.frame = CGRectMake(0, 20, 320, 460);
scroll.pagingEnabled = YES;
scroll.contentSize = CGSizeMake(320 * 2, 460);
scroll.showsHorizontalScrollIndicator = NO;
scroll.showsVerticalScrollIndicator = NO;
scroll.scrollsToTop = NO;
scroll.delegate = self;
scroll.pagingEnabled = YES;
viewNavController1 = [[viewNavController1 alloc] init];
ctrl = [[UITabBarController alloc] init];
ViewController1 *viewC1= [[ViewController1 alloc] initWithNibName:#"ViewController1" bundle:nil];
UINavigationController *control = [[UINavigationController alloc] initWithRootViewController:viewC1];
viewC1.title = #"Title1";
[viewC1 release];
ViewController2 *viewC2 = [[ViewController2 alloc] initWithNibName:#"ViewController2" bundle:nil];
UINavigationController *control2 = [[UINavigationController alloc] initWithRootViewController:viewC2];
viewC2.title = #"Title2";
[viewC2 release];
UINavigationController *control3 = [[UINavigationController alloc] init];
ViewController3 *viewC3 = [[ViewController3 alloc] initWithNibName:#"ViewController3" bundle:nil];
[control3 pushViewController:viewC3 animated:NO];
viewC3.title = #"Title3";
[viewC3 release];
[ctrl setViewControllers:[NSArray arrayWithObjects:control,control2,control3,nil]];
CGRect frame = scroll.frame;
frame.origin.x = frame.size.width * 0;
frame.origin.y = 0;
viewNavController1.view.frame = frame;
viewC4 = [[ViewController4 alloc] initWithNibName:#"ViewController4" bundle:nil];
[viewNavController1 pushViewController:viewC4 animated:NO];
[scroll addSubview:viewNavController1.view];
frame = scroll.frame;
frame.origin.x = frame.size.width * 1;
frame.origin.y = 0;
ctrl.view.frame = frame;
[scroll addSubview:ctrl.view];
[scroll scrollRectToVisible:CGRectMake(320, 0, 320, 460) animated:NO];
UITabBarItem *itm = [ctrl.tabBar.items objectAtIndex:0];
itm.image = [UIImage imageNamed:#"img1.png"];
itm = [ctrl.tabBar.items objectAtIndex:1];
itm.image = [UIImage imageNamed:#"img2.png"];
itm = [ctrl.tabBar.items objectAtIndex:2];
itm.image = [UIImage imageNamed:#"img3.png"];
[control release];
[control2 release];
[control3 release];
The problem was that the UITabbarController did not have its view added as the root view of the windows. Which it apparently assumes.
so I had to trick it using:
[vc setWantsFullScreenLayout:YES];
vc is the main ViewController holding the scrollview containing the UITabbarController.
See Offset on UIWindow addSubview for more explanations.
