如何在单元格 Swift 2 中删除项目后重新加载表格视图

我有一个帐户列表TableView。按下按钮后，项目将被删除。到目前为止，一切都很好。

删除后如何刷新tableView？请查看下面的屏幕截图以获取更多信息。

TableView在另一个ViewController中，要删除的按钮在ViewControllerCell中

class cellAccount: UITableViewCell {

    @IBOutlet weak var imgAccount: UIImageView!
    @IBOutlet weak var lblNomeAccout: UILabel!
    @IBOutlet weak var btnDeletar: UIButton!
    @IBAction func btnDeletar(sender: AnyObject) {
        print(btnDeletar.titleLabel?.text)
        if (bdAccount.indexOf((btnDeletar.titleLabel?.text)!) != nil) {
            print(bdAccount.indexOf((btnDeletar.titleLabel?.text)!))
            bdAccount.removeAtIndex(bdAccount.indexOf((btnDeletar.titleLabel?.text)!)!)
            bdAccount.sortInPlace()


            self.tableView.reloadData()  // How to Reload???



        }
    }
    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
    }

}

您可以尝试这种方式，添加一个NSNotificationCenter在你的视图控制器中viewDidLoad

NSNotificationCenter.defaultCenter().addObserver(self, selector: "reloadData:",name:"reloadData", object: nil)

然后是它的selector, 表示函数

func reloadData(notification:NSNotification){
    // reload function here, so when called it will reload the tableView
    self.TableView.reloadData()
}

将上述内容添加到 viewController 后，现在您需要调用/触发此通知来重新加载 TableView。所以在你的里面btnDelete点击，

@IBAction func btnDeletar(sender: AnyObject) {
    print(btnDeletar.titleLabel?.text)
    if (bdAccount.indexOf((btnDeletar.titleLabel?.text)!) != nil) {
        print(bdAccount.indexOf((btnDeletar.titleLabel?.text)!))
        bdAccount.removeAtIndex(bdAccount.indexOf((btnDeletar.titleLabel?.text)!)!)
        bdAccount.sortInPlace()


        // This will fire the Notification in your view controller and do the reload.
        NSNotificationCenter.defaultCenter().postNotificationName("reloadData",object: self)

    }
}
