Question

我在表格视图中使用自定义单元格我有两个用于图标的标签（我使用字体中的图标），第二个是单元格的标题

我有一个来自字体的图标数组，我希望在每30秒后在标签中制作它们。

例如，我有一个图标数组（消息，脸书，推特，Instagram）。我想第一次在标签中取第一个数据，然后每30秒取一个标签。

        socialIcon = ["\u{ea61}","\u{e8c7}","\u{e8c8}","\u{e324}"] // partage + facebook + tweeter + message
    var timer = NSTimer.scheduledTimerWithTimeInterval(1.0, target: self, selector: "animate", userInfo: nil, repeats: true)
timer.fire()



override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
        /*let cell =  UITableViewCell()
        cell.textLabel?.text = "Stretch Header"
        cell.selectionStyle = .None*/

  //  let cell = tableView.dequeueReusableCellWithIdentifier(reuseIdentifier) as! ParametreViewCell
    let cell = tableView.dequeueReusableCellWithIdentifier(reuseIdentifier, forIndexPath: indexPath) as! ParametreViewCell

    cell.iconLabel.font = UIFont(name:"innovi", size: 20)

    cell.titleLabel.text = self.paramTable[indexPath.row]

    if indexPath.row == 0
    {
        func animate()
        {
        UIView.transitionWithView(cell.iconLabel,
                                  duration: 1.0,
                                  options: [.CurveEaseInOut],
                                  animations: { () -> Void in
                                    if (self.counter < self.socialIcon.count)
                                    {
                                        self.counter += 1
                                        cell.iconLabel.text = self.socialIcon[self.counter]
                                        print (cell.iconLabel.text )
                                    }

            }, completion: nil)

        }
    }
    else
    {
        cell.iconLabel.text = self.iconTable[indexPath.row]
    }


    return cell
}

 override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {

    let cell = tableView.dequeueReusableCellWithIdentifier(reuseIdentifier, forIndexPath: indexPath) as! ParametreViewCell

    cell.iconLabel.font = UIFont(name:"innovi", size: 20)

    cell.titleLabel.text = self.paramTable[indexPath.row]

    if indexPath.row == 0
    {
        cell.iconLabel.text = self.socialIcon[0]
        NSTimer.scheduledTimerWithTimeInterval(5.0, target: self, selector: #selector(animate), userInfo: nil, repeats: true)

    }
    else
    {
        cell.iconLabel.text = self.iconTable[indexPath.row]
    }


    return cell
}

func animate() {
    var indexPath = NSIndexPath.init(forRow: 0, inSection: 0)
    if let ifExists = tableView.indexPathsForVisibleRows?.contains(indexPath)
        where ifExists {
        let customCell = tableView.cellForRowAtIndexPath(indexPath) as! ParametreViewCell
        UIView.transitionWithView(customCell.iconLabel,
                                  duration: 1.0,
                                  options: [.CurveEaseInOut],
                                  animations: { () -> Void in
                                    if (self.counter < self.socialIcon.count )
                                    {
                                        customCell.iconLabel.text = self.socialIcon[self.counter]
                                        self.counter += 1

                                    }
                                    else
                                    {
                                         self.counter = 0
                                    }
            }, completion: nil)
    }
}
