Adding custom view above tab bar controller/navigation controller?

I tried the following code, in an attempt to get the custom view displaying above the tab bar controller (which happens to have a navigation controller within all of it's tabs).

The problem is that it overlays on top of the navigation bar, and I want the navigation bar to be moved down.

I tried setting the frame of the tab bar controller, but that didn't move it at all.

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{    
    // Override point for customization after application launch.
    // Add the tab bar controller's current view as a subview of the window
    //self.tabBarController.view.frame = CGRectMake(0, 62, 320, 320);
    self.window.rootViewController = self.tabBarController;

    [self.window makeKeyAndVisible];

    // setting up the header view
    self.headerView = [[HeaderView alloc] initWithFrame:CGRectMake(0, 20, 320, 42)];
    [self.window addSubview:self.headerView];

    // setting up facebook stuff
    AgentSingleton *agentSingleton = [AgentSingleton sharedSingleton];
    agentSingleton.facebook = [[Facebook alloc] initWithAppId:APP_ID];

    return YES;
}

Any ideas?

I had the same problem and ended up doing something like this:

newView.frame = tabBarController.tabBar.frame
tabBarController.view.addSubview(newView)

Adding the view to the tabBarController and using the frame of the current tabbar as the position of the new view did the trick.

You can do something like that:

if let indeedTabBarController = self.tabBarController {

    let buttonHeight: CGFloat = 49 // height of tab bar
    let buttonWidth = UIScreen.main.bounds.width / 3 // in case if you have 3 tabs
    let frame = CGRect(x: 0, y: UIScreen.main.bounds.height - buttonHeight, width: buttonWidth, height: buttonHeight)
    let button = UIButton(frame: frame)
    button.addTarget(self, action: #selector(self.someAction), for: .touchUpInside)

    indeedTabBarController.view.addSubview(button)
}

override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(animated)
if let indeedTabBarController = self.tabBarController {
    let buttonHeight: CGFloat = view.safeAreaInsets.bottom + 44
    let buttonWidth = UIScreen.main.bounds.width
    let frame = CGRect(x: 0, y: UIScreen.main.bounds.height - buttonHeight, width: buttonWidth, height: 44)
    let vw = UIView(frame: frame)
    vw.backgroundColor = .red
    indeedTabBarController.view.addSubview(vw)
  }
}
