Question

我有一个带有来自Firebase数据库的3个变量的表视图控制器。我想将此数据传递给Details View Controller。现在，我只有＆＃34; title＆＃34;（label1）从TableVC传递到Details VC。

我怎样才能将其余数据（label2和label3）传递给DetailsVC？

MondayTableVC：

override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {

        let cell = tableView.dequeueReusableCellWithIdentifier("Cell_Monday")

        let messageSnapshot: FIRDataSnapshot! = conf[indexPath.row]
        let message = messageSnapshot.value as! Dictionary<String, String>

        // print(message)

        let label1 = cell?.viewWithTag(1) as! UILabel
        label1.text = message["title"]

        let label2 = cell?.viewWithTag(2) as! UILabel
        label2.text = message["place"]

        let label3 = cell?.viewWithTag(3) as! UILabel
        label3.text = message["date"]


        return cell!

    }

    override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {



        let messageSnapshot: FIRDataSnapshot! = conf[indexPath.row]
        let message = messageSnapshot.value as! Dictionary<String, String>

        let storyBoard : UIStoryboard = UIStoryboard(name: "Main", bundle:nil)
        let monDetails = storyBoard.instantiateViewControllerWithIdentifier("mondayDetails") as! MondayViewController
        monDetails.title = message["title"]


        monDetails.mondayDetailDict = message
        self.navigationController?.pushViewController(monDetails, animated: true)


    }

星期一（细节）的ViewController：

class MondayViewController: UIViewController {

    var mondayDetailDict: Dictionary<String, String> = Dictionary()


    @IBOutlet weak var label1: UILabel!


    override func viewDidLoad() {
        super.viewDidLoad()


    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()

    }


   }

有人可以帮助解决这一挑战吗？

Answer 1

override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {

        let messageSnapshot: FIRDataSnapshot! = conf[indexPath.row]
        let message = messageSnapshot.value as! Dictionary<String, String>

        let storyBoard : UIStoryboard = UIStoryboard(name: "Main", bundle:nil)
        let monDetails = storyBoard.instantiateViewControllerWithIdentifier("mondayDetails") as! MondayViewController
        monDetails.title = message["title"]
        let cell = tableView.cellForRow(at: indexPath) as! CellClass

        let label2 = cell?.viewWithTag(2) as! UILabel
        monDetails.field2 = label2.text

        let label3 = cell?.viewWithTag(3) as! UILabel
        monDetails.field3 = label3.text

        monDetails.conferenceDetailDict = message
        self.navigationController?.pushViewController(monDetails, animated: true)


    }

Answer 2

您实际上没有将值分配给label1。将MondayViewController更改为此：

class MondayViewController: UIViewController {

var mondayDetailDict: Dictionary<String, String> = Dictionary()

@IBOutlet weak var label1: UILabel!

override func viewDidLoad() {
    super.viewDidLoad()
    label1.text = mondayDetailDict["place"]
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()

}
}
