自定义RootViewController方法

• iOS13后，需要在SceneDelegate中willConnectToSession方法中去自定义viewcontroller

• (void)scene:(UIScene )scene willConnectToSession:(UISceneSession )session options:(UISceneConnectionOptions )connectionOptions { // Use this method to optionally configure and attach the UIWindow window to the provided UIWindowScene scene. // If using a storyboard, the window property will automatically be initialized and attached to the scene. // This delegate does not imply the connecting scene or session are new (see application:configurationForConnectingSceneSession instead). UIWindowScene windowScene = (UIWindowScene )scene; self.window = [[UIWindow alloc] initWithWindowScene:windowScene]; self.window.backgroundColor = [UIColor purpleColor]; UIViewController VC = [[UIViewController alloc]init]; UINavigationController *NVC = [[UINavigationController alloc]initWithRootViewController:VC]; [self.window setRootViewController:NVC]; [self.window makeKeyAndVisible]; }
