Swift Question

Dismiss View Controller within UITabController

I have the following stack on my Storyboard

-> Navigation Controller
-> MyCoursesViewController (does a prepareForSegue to next 'view')
-> Course Info UITabController (I select Setting Tab)
-> Setting Navigation Controller
-> SettingViewController

When I am in the Setting Tab: SettingViewController, I have a UIButton which says ‘Exit Course’ and I want it to go back to MyCoursesViewController. How can I pop to reach this view controller?

I tried the things below:

self.tabBarController?.navigationController?.dismissViewControllerAnimated(true, completion: nil)
self.navigationController?.tabBarController?.dismissViewControllerAnimated(true, completion: nil)
self.dismissViewControllerAnimated(true, completion: nil)

but to no avail.

Is there a way to simply dismiss or do I need to implement a delegate from MyCoursesViewController to pass to the SettingViewController via the UITabController? I am not sure how to pass a delegate to
MyCourses -> Course Info Tab -> Setting
. If it was
MyCourses -> Setting
, that’s just a simple delegate pass from class to class but the confusing part is the intermediate Tab controller.

From your description, it sound like MyCoursesViewController is the rootViewController of your NavigationController.

You pushed the CourseInfoUITabController to your stack and your SettingViewController is actually embedded in a UINavigationController therefore you can do this:
