Как изменить заголовок элемента панели вкладок у делегата приложения. В настоящее время у меня есть 5 элементов панели вкладок. Как программно изменить заголовок элемента панели 5 вкладок при запуске?

Мой tab bar controller настроен следующим образом. У меня 5 tab bar controller и 4 из которых встроены в navigation controller. Тогда у меня есть один, который является автономным ViewController

Пожалуйста, помогите.
