Question

我有一个带有自定义Prototype Cell的tableview控制器。该单元格包含2个标签。我试图从Parse类返回2个值。一个字段称为Notes，是一个String值。另一个字段称为CreditAmount，是一个数字值。我很难在tableview中返回数值（Credit Amount）。

以下是tableview控制器的代码：

导入UIKit 导入Parse 进口基金会

class TableViewController：UITableViewController {

var note = [String]()
var credit = [NSInteger]()

var refresher：UIRefreshControl！

override func viewDidLoad() {
    super.viewDidLoad()

      self.tableView.reloadData()

    updateNotes()

    self.refresher = UIRefreshControl()
    self.refresher.attributedTitle = NSAttributedString(string: "Pull to refresh")
    self.refresher.addTarget(self, action: "refresh:", forControlEvents: UIControlEvents.ValueChanged)
    self.tableView.addSubview(refresher)
}


func updateNotes() {

    let query = PFQuery(className: "Paydown")

    query.findObjectsInBackgroundWithBlock({ (objects:[AnyObject]?, error: NSError?) -> Void in

        self.note.removeAll(keepCapacity: true)
        self.credit.removeAll(keepCapacity: true)

        if let objects = objects as? [PFObject] {

            for object in objects {

              // var noted = object as PFObject
                self.note.append(object["Notes"] as! String)
                self.credit.append(object["CreditAmount"] as! NSInteger)

            }

            self.tableView.reloadData()


        } else {

            //println(error)
        }

        self.refresher.endRefreshing()

})

}


func refresh() {

    updateNotes()

}

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

// MARK: - Table view data source

override func numberOfSectionsInTableView(tableView: UITableView) -> Int {
    // #warning Potentially incomplete method implementation.
    // Return the number of sections.
    return 1

}

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


return note.count

}


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


    let myCell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as! cell


    myCell.notesLabel.text = note[indexPath.row]
    myCell.amountLabel.text = credit[indexPath.row]

    return myCell

}

}

以下是我的客户单元格的代码：

导入UIKit import Parse

类单元格：UITableViewCell {

@IBOutlet weak var notesLabel: UILabel!

@IBOutlet weak var amountLabel: UILabel!

override func awakeFromNib() {
    super.awakeFromNib()
    // Initialization code
}

override func setSelected(selected: Bool, animated: Bool) {
    super.setSelected(selected, animated: animated)

    // Configure the view for the selected state
}

}

myCell.amountLabel.text = credit [indexPath.row]导致错误：无法将类型为NSInteger（aka int）的值赋给String类型的值。如何让号码字段起作用？

Answer 1

更新

myCell.amountLabel.text = credit[indexPath.row]

要

myCell.amountLabel.text = "\(credit[indexPath.row])"

从Parse返回到Tableview自定义单元格的数字字段
