错误：“无法将具有标识符Cell的单元格出列”

Question

我正在使用以下viewController设置

我要做的是从array访问placesTabBar个地点，并在两个navigationControllers中显示这些地点。其中一个控制器将包含一个位置列表，而另一个控制器将仅用于您正在参加的位置。在选择一个单元格时，它会在切换时更新另一个视图控制器，表示你要去那个地方。我使用以下代码：

AllPlaces ViewController

class AllPlaces: UITableViewController {

var delegate:placesTabBar!

override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    // #warning Incomplete method implementation.
    // Return the number of rows in the section.
    return delegate.placeDataArray.count
}


override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as! UITableViewCell

    cell.textLabel?.text = delegate.placeDataArray[indexPath.row].description

    return cell
}

}

AttendingPlaces ViewController     class AttendingPlaces：UITableViewController {

var delegate:placesTabBar!

override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {

    return delegate.placeDataArray.count
}


override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as! UITableViewCell

    cell.textLabel?.text = delegate.placeDataArray[indexPath.row].description
    return cell
}

}

TabBarController

class placeData: Equatable {
var description : String
var selected : Bool

init (description : String, selected : Bool) {
    self.description = description
    self.selected = selected
}
}
class placesTabBar: UITabBarController, CustomTabBarDelegate {

var placeDataArray = Array<placeData>()

override func viewDidLoad() {

    placeDataArray = [placeData(description: "Afghanistan", selected: false), placeData(description: "Albania", selected: false)]

    var table1 = AttendingPlaces()
    var table2 = AllPlaces()

    table1.delegate = self
    table2.delegate = self

    var navController1 = UINavigationController(rootViewController: table1)
    var navController2 = UINavigationController(rootViewController: table2)

    self.viewControllers = [navController1, navController2]

}



override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}
}

现在我只是尝试使用数组中的两个位置加载表。但是，我得到一个“无法使用标识符Cell出列的单元格”错误。在tableViewControllers中都正确设置了重用标识符，因此我不确定发生了什么。这可能是我尝试在两个viewControllers之间共享数据的方式吗？
