I have an iOS application that has two tabs with navigation controllers on them. One of the tabs has a logout button on it. The logout button invokes a function that performs a popToRootViewController on the navigation controller on the other tab. This will display the following message in the debugger:

Unbalanced calls to begin/end appearance transitions for <UIViewController>.

This message does not appear if I change to the tab that I am trying to clear, and then call popToRootViewController or if I manually loop through all the view controllers in that navigation controller and call popViewController. The animated flag of popToRootViewController is set to false in both cases. Is this functionality intended?

  • Could you make your question a little more clear? Perhaps post some code? I can't understand the description of your problem. – Farini May 17 '17 at 01:38

Set the popRootViewAnimation to "false", hope it'll resolve your issue.

self.navigationController?.popToRootViewControllerAnimated(false)

If you want some details about your issue, then check this link:
