'尝试在多个TableView部分中划分NSObject数组时，无法下标类型[[DataMode]]'的值

Question

我试图在TableView中的2个不同部分划分2个NSObject数组，但我在xCode中看到错误'无法下标类型为[[DataMode]]的值。

我的DataModel是：

class dataModel: NSObject {
    var name:String
    var val:Double
    var prot:Double
    var fat:Double
    var cal:Double
    var grams:Double
    var total:Double

    init(name: String, val: Double,prot: Double, fat: Double, cal:Double, grams: Double, total: Double){
        self.name = name
        self.val = val
        self.prot = prot
        self.fat = fat
        self.cal = cal
        self.grams = grams
        self.total = total
    }  
}

阵列：

var MeatData = [dataModel(name: "food1", val: 5.0, prot: 17.5, fat: 11.7, cal:178.0, grams: 0.0, total: 0.0),
    dataModel(name: "meat2", val: 6.0, prot: 19.0, fat: 7.8, cal: 148, grams: 0.0, total: 0.0),
    dataModel(name: "meat3", val: 7.0, prot: 24.5, fat: 29.7, cal: 370.0, grams: 0.0, total: 0.0)]


var BreadData = [dataModel(name: "bread1", val: 5.0, prot: 17.5, fat: 11.7, cal: 178.0, grams: 0.0, total: 0.0),
    dataModel(name: "bread2", val: 6.0, prot: 19.0, fat: 7.8, cal: 148, grams: 0.0, total: 0.0),
    dataModel(name: "bread3", val: 7.0, prot: 24.5, fat: 29.7, cal: 370.0, grams: 0.0, total: 0.0)]

TableViewController：

导入UIKit

class MeatTableViewController: UITableViewController {

    let sections = ["Meat","Bread"]
    let items = [[MeatData], [BreadData]]

    @IBOutlet weak var addBarButton: UIBarButtonItem!
    var stringToPass = ""
    var valueToPass:Double!
    var protToPass:Double!
    var fatToPass:Double!
    var calToPass:Double!

    //vars additional food

    var NewFood = ""
    var NewCarbs:Double!
    var NewProt:Double!
    var NewFat:Double!
    var NewCal:Double!

    var NewlyAddedFood = dataModel(name: "", val: 0.0, prot: 0.0, fat: 0.0, cal: 0.0, grams: 0.0, total: 0.0)

    @IBOutlet var meatTable: UITableView!

    override func viewDidLoad() {
        super.viewDidLoad()

    }

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

    override func tableView(tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
        return self.sections[section]
    }

    // MARK: - Table view data source

    override func numberOfSectionsInTableView(tableView: UITableView) -> Int {
        // #warning Incomplete implementation, return the number of sections
        return sections.count
    }

    override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        // #warning Incomplete implementation, return the number of rows
        return items[section].count
    }

    override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
        //let cell = tableView.dequeueReusableCellWithIdentifier("meatCell", forIndexPath: indexPath) as! MeatTableViewCell
        let cellIdentifier = "meatCell"
        let Meatcell = tableView.dequeueReusableCellWithIdentifier(cellIdentifier, forIndexPath: indexPath) as! MeatTableViewCell
        let meatIndex = MeatData[indexPath.row]

        Meatcell.titleLabel?.text = items[indexPath.section][indexPath.row]
        //Meatcell.titleLabel.text = meatIndex.name
        //Meatcell.valLabel.text = String(meatIndex.val)
        //Meatcell.protEMPTY.text = String(meatIndex.prot)
        //Meatcell.fatEMPTY.text = String(meatIndex.fat)
        //Meatcell.calEMPTY.text = String(meatIndex.cal)

        return Meatcell
    }

    override func tableView(tableView: UITableView, commitEditingStyle editingStyle: UITableViewCellEditingStyle, forRowAtIndexPath indexPath: NSIndexPath) {
        if editingStyle == UITableViewCellEditingStyle.Delete {
            MeatData.removeAtIndex(indexPath.row)
            tableView.deleteRowsAtIndexPaths([indexPath], withRowAnimation: UITableViewRowAnimation.Automatic)
        }
    }

    override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
        print("You selected cell #\(indexPath.row)!")
    let indexPathVal: NSIndexPath = tableView.indexPathForSelectedRow!
        print("\(indexPathVal)")
        let currentCell = tableView.cellForRowAtIndexPath(indexPathVal) as! MeatTableViewCell;
        print("\(currentCell)")
        print("\(currentCell.titleLabel?.text!)")

        stringToPass = currentCell.titleLabel.text!
        valueToPass = Double(currentCell.valLabel.text!)
        protToPass = Double(currentCell.protEMPTY.text!)
        fatToPass = Double(currentCell.fatEMPTY.text!)
        calToPass = Double(currentCell.calEMPTY.text!)

        print(stringToPass)
        print(valueToPass)
        print(protToPass)
        print(fatToPass)
        print(calToPass)
       self.performSegueWithIdentifier("showCalc", sender: self)
    }

    override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {

        //Here i am checking the Segue and Saving the data to an array on the next view Controller also sending it to the next view COntroller
        if segue.identifier == "showCalc"{
            //Creating an object of the second View controller
            let DestController = segue.destinationViewController as! CalcViewController
            //Sending the data here
            DestController.passedString = stringToPass
            DestController.passedValue = valueToPass
            DestController.passedProt = protToPass
            DestController.passedFat = fatToPass
            DestController.passedCal = calToPass 
        }
    }

    @IBAction func done(segue:UIStoryboardSegue) {

        let carDetailVC = segue.sourceViewController as! AdditionalFood

        NewFood = String(carDetailVC.AddedFood)
        NewCarbs = carDetailVC.AddedCarbs
        NewProt = carDetailVC.AddedProteins
        NewFat = carDetailVC.AddedFat
        NewCal = carDetailVC.AddedCal

        NewlyAddedFood.name = NewFood
        NewlyAddedFood.val = NewCarbs
        NewlyAddedFood.prot = NewProt
        NewlyAddedFood.fat = NewFat
        NewlyAddedFood.cal = NewCal

        MeatData.insert(NewlyAddedFood, atIndex: 0)

        self.tableView.reloadData()
    }
}

结果我发现了一条错误消息

  

'不能在这里下标[[DataMode]]类型的值：   Meatcell.titleLabel？.text = items [indexPath.section] [indexPath.row]
