无法投类型的UITableViewCell的值设置为“ActuTblCell”

Question

我试图做自动高度来排一个RSS阅读器，但我得到这个错误：

Could not cast value of type 'UITableViewCell' (0x1117bfc68) to 'package.ActuTblCell' (0x10fedca70). 

ActualitesViewController

    optional func toggleLeftPanel()

    @IBOutlet var tableView: UITableView! 

    var parser = NSXMLParser() 
    var posts = NSMutableArray()

    var element = NSString() 
    var title1 = NSMutableString()

     self.navigationController?.navigationBar.titleTextAttributes = [NSFontAttributeName: UIFont(name: "Gotham", size: 13)!, NSForegroundColorAttributeName : UIColor.whiteColor()] 
     self.title = "ACTUALITÉS" 

     let nib = UINib(nibName: "actuVwCell", bundle: nil) 
     tableView.registerNib(nib, forCellReuseIdentifier: "cell") 


     self.beginParsing()

ActuTblCell

import UIKit 

class ActuTblCell: UITableViewCell { 
    @IBOutlet var titleActuCell: UILabel! 

    @IBOutlet var descriptionActuCell: UILabel! 

    @IBOutlet var dateActuCell: 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 
    } 
} 

在我mainstoryboard我：

• 我的场景类是：ActualitesViewController
• 我的TableViewCell类：ActuTblCell

Answer 1

你的电池类是ActuTblCell，但您注册笔尖与名actuVwCell

let nib = UINib(nibName: "actuVwCell", bundle: nil)

检查，也许问题是在这里。否则，建议根据类别命名笔尖。

Answer 2

你的代码有错误的位置：

let cell = tableView.dequeueReusableCellWithIdentifier("cell") as! ActuTblCell 

你忘了设置自定义类的细胞对ActuTblCell。
