Question

这里我试图使用带有UISegmentController的导航控制器。我在这里使用了三个不同选项卡的开关盒。点击它应该改变私人公众和受保护但可以看到哪些价值在数组中声明。

    @IBOutlet var myTableView: UITableView!
    @IBOutlet var mySegmentControll: UISegmentedControl!

    var privateList:[String] = ["Private Item 1","Private Item 2"]
    var protected:[String] = ["Protected 1","protected 2"]
    var publicList:[String] = [" public 1","Public 2"]

    override func viewDidLoad() {
        super.viewDidLoad()
        myTableView.delegate = self;
        myTableView.dataSource = self;
    }

我的代码无法返回cell1我没有任何错误，但我看不到输出我的数组。

    @IBAction func refreshbtn(sender: AnyObject)
    {
    }

    @IBAction func mySegmentValueChanged(sender: AnyObject) {
    }

    func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        var retunValue = 0

        switch (mySegmentControll.selectedSegmentIndex){
        case 1 :
            retunValue = privateList.count
            break
        case 2:
            retunValue = publicList.count
            break
        case 3:
            retunValue = protected.count
            break
        default :
            break
        }
        return retunValue
    }


    func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell
    {
        let cell1 = tableView.dequeueReusableCellWithIdentifier("cell1", forIndexPath: indexPath)
        switch (mySegmentControll.selectedSegmentIndex){
        case 1:
            cell1.textLabel!.text = privateList[indexPath.row]
            break
        case 2:
            cell1.textLabel!.text = publicList[indexPath.row]
            break
        case 3:
            cell1.textLabel!.text = protected[indexPath.row]
            break
        default :
            cell1.textLabel?.text = "Boat"
            break
        }
        //cell.petname.text
        return cell1
    }
}

Answer 1

  public static BigDecimal roundTo5Cents(BigDecimal amount)
  {
    amount = amount.multiply(new BigDecimal("2"));
    amount = amount.setScale(1, RoundingMode.HALF_UP);
    // preferred scale after rounding to 5 cents: 2 decimal places
    amount = amount.divide(new BigDecimal("2"), 2, RoundingMode.HALF_UP);
    return amount;
  }

我的表视图控制器上没有返回数组值
