Ios Can'；无法从另一个视图控制器获取阵列

我正在做一个定向（不知道它的英文名称是否正确）应用程序。您可以扫描二维码，然后将结果发送给您的老师。我正在使用Multipeer连接从学生电话和老师那里发送结果。我有一个UITableViewController，我想为另一个视图控制器->UIViewController创建一个数组（带有一个结构，2个值）。这就是问题所在。当我尝试将它“发送”到另一个viewControler时，它无法到达末尾或其他位置。我已经尝试了我能尝试的一切（controlsGetShared是一次尝试），但仍然不起作用…：(

结构如下所示

struct Control {
let name: String
let code: String 
}

UITableViewController看起来像

import UIKit

class ControlViewController: UITableViewController {

var controlsGet = [Control] ()
var controlsGetShare = [Control] ()

var def = NSUserDefaults.standardUserDefaults()

var valueName: String = ""
var valueCode: String = ""

@IBAction func done(segue: UIStoryboardSegue) {
    var scanVc = segue.sourceViewController as ScanViewController
    valueName = scanVc.name
    valueCode = scanVc.code

    println("sendToSendFile \(valueName)  \(valueCode)")

    controlsGet.append(Control(name: valueName, code: valueCode))
    //controlsGetShare.append(Control(name: valueName, code: valueCode))
    println("\(self.controlsGet.count) shareArray \(self.controlsGetShare.count)")
}

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
    controlsGetShare = controlsGet
    println("preparaForSegueCount \(controlsGetShare.count)")
}

override func viewDidLoad() {
    println("viewDidLoad")
    tableView.reloadData()

    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return self.controlsGet.count
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let cell = self.tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as UITableViewCell

    //for index in controlsGet {

    var control : Control

    control = controlsGet[indexPath.row]

    cell.textLabel.text = control.name
    cell.detailTextLabel?.text = control.code
    //}
    return cell
}
override func tableView(tableView: UITableView, commitEditingStyle editingStyle: UITableViewCellEditingStyle, forRowAtIndexPath indexPath: NSIndexPath) {
    if editingStyle == .Delete {
        controlsGet.removeAtIndex(indexPath.row)
        tableView.deleteRowsAtIndexPaths([indexPath], withRowAnimation: .Fade)
    } else if editingStyle == .Insert {
        // Create a new instance of the appropriate class, insert it into the array, and add a new row to the table view
    }
}
}

Ant发送UIViewControler

    // create the browser viewcontroller with a unique service name
    self.browser = MCBrowserViewController(serviceType:serviceType,
        session:self.session)

    self.browser.delegate = self;

    self.assistant = MCAdvertiserAssistant(serviceType:serviceType,

大部分代码来自我在互联网上找到的源代码，这就是所有评论的原因。谢谢

id您没有正确实现模型层有什么特殊原因吗？您本可以避免此类问题。
