ios - 获取错误类 DetailCell 没有初始化程序

Question

import UIKit
import CoreData

class DetailCell: UITableViewCell {

    @IBOutlet var articleNumber: UILabel!
    @IBOutlet var name: UILabel!
    @IBOutlet var stock: UILabel!

    var post: AnyObject
        {

         didSet
            {
                self.configure()
        }

    }

    override func awakeFromNib() {
        super.awakeFromNib()
         self.articleNumber?.text = nil
        self.name?.text = nil
        self.stock?.text = nil
    }
    func configure()
    {

      self.articleNumber?.text = post.objectForKey("itemName") as? String
        self.name?.text = post.objectForKey("itemName") as? String
        self.stock?.text = post.objectForKey("stock")  as? String
    }

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

        // Configure the view for the selected state
    }

}

我收到错误消息，指出类 DetailCell 没有初始化程序。 我不知道为什么会这样。

只需在 post 实例声明和最终代码中添加 ! 和 AnyObject 即可:

var post: AnyObject! {

    didSet
    {
        self.configure()
    }

}
