计时器到期时快速删除表格 View 单元格

Question

我努力寻找解决方案，但我被困住了。在每个单元格中都有一个带有计时器的自定义表格 View 。当计时器到期时，即使单元格在屏幕外，单元格也应该被删除，它应该被删除并且不应该显示。

 func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let cell = self.tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as! iDealCell
    //        cell.SponsorLogo.image = UIImage(named: "back.png")!
    cell.SponsorName.text = iDeals[indexPath.row].SponsorName;
    cell.Distance.text = iDeals[indexPath.row].Distance;
    cell.Type.text = iDeals[indexPath.row].Type;
    cell.iDealTimer.font = UIFont(name: "DBLCDTempBlack", size: 18.0)

    onHourFromNow = NSDate(timeInterval: 10, sinceDate: timeNow)
    let TimeDiffInSec = NSCalendar.currentCalendar().components(.Second, fromDate: timeNow, toDate: onHourFromNow, options: []).second
    cell.TimeDiffInSec = TimeDiffInSec
    cell.kickOffCountdown()
    cell.backgroundColor = UIColor.clearColor()
    cell.delegate = self
    return cell
}

in cell class, three functions to initialise and run the timer

func kickOffCountdown(){
    self.setCountDown()
    Timer.invalidate()
    Timer = NSTimer.scheduledTimerWithTimeInterval(1.0, target: self, selector: #selector(iDealCell.setCountDown), userInfo: nil, repeats: true)                     
}

func secondsToHoursMinutesSeconds (seconds : Int) -> (String, String, String) {
    let hours = seconds / 3600
    let minutes = (seconds % 3600) / 60
    let seconds = (seconds % 3600) % 60

    let hoursString = hours < 10 ? "0\(hours)" : "\(hours)"
    let minutesString = minutes < 10 ? "0\(minutes)" : "\(minutes)"
    let secondsString = seconds < 10 ? "0\(seconds)" : "\(seconds)"
    return (hoursString, minutesString, secondsString)
}

func setCountDown() {
    if(TimeDiffInSec > 0) {
        let (h,m,s) = secondsToHoursMinutesSeconds(TimeDiffInSec)
        self.iDealTimer.text = "\(h):\(m):\(s)"
        TimeDiffInSec = TimeDiffInSec - 1
    }
    else{
        self.iDealTimer.text = "EXPIRED"
        if let delegate = self.delegate {
            delegate.DeleteiDealID(1)
        }
        Timer.invalidate()
    }
}

任何帮助将不胜感激

只要你的时间到期，你可以做一些简单的事情，你可以从你的字典数组中删除那些用于行计数的值。

这里很简单，您的所有表格单元格都取决于您的行数删除器，通过删除特定的数组对象来删除特定的单元格。

例子:

if timerExpire == true {
        array.removeAtIndex(5)
        self.table.reloadData()
}
