Unwind segue and nav button items not triggering after tab bar controller added

Question

I'm trying to implement an unwind segue that will take me from the last view controller back to the todo-list controller.

Here's my storyboard

Without the tab bar controller, the unwind segue works fine. However, as soon as I add the tab bar controller, the unwind stopped triggering.

What am I doing wrong?

Thanks

Edit: Also, actions created on the bar button in the last view controller do not trigger when the tab bar controller is implemented

Answer 1

I have had a similar situation and I was able to resolve it by setting the Modal segue to "Presentation: Current Context" instead of "Default" in the Attributes Inspector (screenshot here: https://cloudup.com/cHFyH8OOY9D).

That is, the segue arrow between the Table View and the second Navigation Controller in your screenshot above.

Answer 2

I've had a similar issue with unwind segues not being called with view controllers within a TabBarController.

The solution is to create a custom TabBarController class, and have the unwind segue action in that class. You will then be able to pass a message to the current tab bar view controller.
