ios - Tab bar's navbar stuck under custom navbar? -

i implementing custom nav bar of application, transition tab bar based navigation paradigm other portions of app.

when switch tab bar portion of app , navigate "more" section of tab bar controller, navbar has "edit" button of more section obscured custom navbar.

i have tried removing navbar view, bringing tab bar's navbar top of view, etc.

the goal here gain access edit button's functionality in order rearrange icons on tab bar.

i'd either invoke edit functionality of tab bar programmatically or bring tab bar's navbar front of view.

thanks in advance!
