how to change color of navigation back button

[vkcldhkd]

Thanks for making a good library.
I want to change the color of the navigation back button. But it did not change.
Help me...

guard let openSourceVC = VTAcknowledgementsViewController.acknowledgementsViewController () else {return}
                
////// NOT CHANGE!!
openSourceVC.navigationController? .navigationBar.tintColor = .black
openSourceVC.navigationController? .navigationBar.barTintColor = .black
//////

openSourceVC.navigationItem.title = "SETTING_TEXT8" .localized ()
                
openSourceVC.headerText = ""
openSourceVC.footerText = ""
push (vc: openSourceVC)

Hello (and sorry for this late response 😅),

The problem in this code is that the VTAcknowledgementsViewController instance doesn’t have a navigation controller. So openSourceVC.navigationController? returns nil, and fails silently.

The fix would depend on your specific interface, but if the current view controller already has a navigation controller, it could be as simple as this:

self.navigationController?.navigationBar.tintColor = .black
self.navigationController?.navigationBar.barTintColor = .black

My solution is to create a new ViewController!

1. Get the acknowledgments from the AcknowledgeListViewController.
2. binding Custom UI with acknowledgments

        let acknowListVC = AcknowListViewController()
        self.acknowledgements = acknowListVC.acknowledgements
        tableView.reloadData()

Glad to hear that you could find a suitable solution 👍
