Question

使用Xcode 6 Beta 5。我正在构建一个tableviewcontroller，这几行代码将无法编译。

func tableView(tableView: UITableView!, cellForRowAtIndexPath indexPath: NSIndexPath!) -> UITableViewCell! 
{
    let cell : OrderHistoryCell = tableView.dequeueReusableCellWithIdentifier("CellForOrderHistory", forIndexPath: indexPath) as OrderHistoryCell

    var orderHistoryDataModel: OrderHistoryDataModel = self.orderItemsArray[indexPath.section][indexPath.row - 1] as OrderHistoryDataModel

    cell.nameLabel.text = orderHistoryDataModel.orderItem.title
    cell.statusLabel.text = orderHistoryDataModel.shipment.shippingStatus.toRaw()

    let imageData: NSData = NSData(contentsOfURL: orderHistoryDataModel.orderItem.imageURL)
    cell.thumbnailImageView.image = UIImage(data: imageData)

    return cell
}

这是编译错误：

此行中的问题

   var orderHistoryDataModel: OrderHistoryDataModel = self.orderItemsArray[indexPath.section][indexPath.row - 1] as OrderHistoryDataModel

你有一个 OrderHistoryDataModel 的阵列数组当你从2个数组中获取对象时，Xcode无法理解对象的类型 - [indexPath.section][indexPath.row - 1] 修复它 - 在orderItemsArray中指定对象的类型

  var orderItemsArray: [[OrderHistoryDataModel]] = []

您还可以尝试通过两个步骤获取对象。将此代码[indexPath.section][indexPath.row - 1]更改为：

var models: [OrderHistoryDataModel] = self.orderItemsArray[indexPath.section]
var orderHistoryDataModel: OrderHistoryDataModel =  models[indexPath.row - 1]

同时清除项目并删除DerivedData文件夹。
