Не удается скрыть UINavigationBar или загрузить внутренний HTML в TabBarController

Question

У меня проблема с скрытием панели навигации в контроллере панели вкладок.Начальная вкладка скрывается правильно, но любые последующие вкладки не будут скрывать свою панель навигации.Другая проблема, которую я имею, состоит в том, что тот же самый HTML-файл не загружается в двух других вкладках.Это действительно странное поведение, так как я получил HTML, чтобы нормально загружаться в других приложениях.

Я также пытался установить свойство в каждой функции делегата, используя этот новый .m Прежде чем вставить его, это распечатка журнала

НО ЕГО ВСЕ ЕЩЕ!Интересно отметить, что viewDidLoad не вызывается после нажатия на вторую вкладку.

Answer 1

Сначала в вашем коде есть ошибка.В вашем ApplicationDidFinishLaunching вы всегда устанавливаете viewcontrollers на navcon1, а не на navcon1, затем navcon2, затем navcon3.

Исправьте это и проверьте, остается ли проблема
