如何在isEditing属性更改时更新UITableView？

Question

I've currently got a TableViewController with a navigation bar with an editButtonItem. My tableview correctly goes into editing mode when I hit this button, but I want to change the labels on my custom UITableViewCell when isEditing changes. I've tried adding the following into cellForRowAt:

   if editingMode {
        cell.timeZoneLabel = ""
    } else {
        cell.timeZoneLabel = timeZone.city
    }

But it seems that the tableView isn't reloaded when isEditing changes.

My next thought was to set the following variable at the start:

var editingMode = false {
    didSet {
        tableView.reloadData()
    }
}

And add the following to viewDidLoad() so I can reload the tableView when isEditing changes:

    editingMode = isEditing

This doesn't seem to work either though. I've tried searching for other solutions but I can't find anyone having the similar problem.

Any guidance would be much appreciated!

In the cell override didTransition(to . The rawValue 0 represents normal state, rawValue 1 is showingEditControl

override func didTransition(to state: UITableViewCell.StateMask) {
    switch state.rawValue {
    case 0: timeZoneLabel = timeZone.city
    case 1: timeZoneLabel = ""
    default: break
    }
}
