Ios 如何将UITableViewCell值正确转换为字符串

因此，我的代码如下所示：

override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath){
  let selectedCell = tableView.cellForRowAtIndexPath(indexPath)! as UITableViewCell
  performSegueWithIdentifier("TVtoVCSegue", sender: selectedCell)        
}

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
  if segue.identifier == "TVtoVCSegue" {
  let otherViewController = segue.destinationViewController as! TTDetailCntr
  otherViewController.CurrentClass = String(sender!) as String
}

cell.textLabel?.text

override func tableView(
  tableView: UITableView, 
  didSelectRowAtIndexPath indexPath: NSIndexPath)
{
  //You would need to create the instance var cellIndex
  self.cellIndex = indexPath.row
  let selectedCell = tableView.cellForRowAtIndexPath(indexPath)! as UITableViewCell
  performSegueWithIdentifier("TVtoVCSegue", sender: selectedCell)
}

override func prepareForSegue(segue: UIStoryboardSegue, 
  sender: AnyObject?) 
{
  if segue.identifier == "TVtoVCSegue" 
  {
    //This code assumes that myModel is an array of structs. 
    //Change this code to fit your data model 
    //(should be the same code you use to set the text in the cell.)
    let stringToPass = myModel[self.cellIndex].stringValue
    let otherViewController = segue.destinationViewController 
      as! TTDetailCntr
    otherViewController.CurrentClass = stringToPass
  }
}

otherViewController.CurrentClass

连接到另一个viewController的标签，其标签上显示：

<UITableViewCell: 0x13f692230; frame = (0 132; 320 44); text = '10.d'; clipsToBounds = YES; autoresize = W; layer = <CALayer: 0x13f692600>>

在这种情况下，它应该是“10.d”。我怎样才能做到这一点

我查了很多问题，如果你发现了重复的问题，请告诉我或解释我做错了什么

提前感谢

您可以访问UITableViewCell“cell”的文本标签，如下所示：

override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath){
  let selectedCell = tableView.cellForRowAtIndexPath(indexPath)! as UITableViewCell
  performSegueWithIdentifier("TVtoVCSegue", sender: selectedCell)        
}

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
  if segue.identifier == "TVtoVCSegue" {
  let otherViewController = segue.destinationViewController as! TTDetailCntr
  otherViewController.CurrentClass = String(sender!) as String
}

cell.textLabel?.text

override func tableView(
  tableView: UITableView, 
  didSelectRowAtIndexPath indexPath: NSIndexPath)
{
  //You would need to create the instance var cellIndex
  self.cellIndex = indexPath.row
  let selectedCell = tableView.cellForRowAtIndexPath(indexPath)! as UITableViewCell
  performSegueWithIdentifier("TVtoVCSegue", sender: selectedCell)
}

override func prepareForSegue(segue: UIStoryboardSegue, 
  sender: AnyObject?) 
{
  if segue.identifier == "TVtoVCSegue" 
  {
    //This code assumes that myModel is an array of structs. 
    //Change this code to fit your data model 
    //(should be the same code you use to set the text in the cell.)
    let stringToPass = myModel[self.cellIndex].stringValue
    let otherViewController = segue.destinationViewController 
      as! TTDetailCntr
    otherViewController.CurrentClass = stringToPass
  }
}

因此，您希望在prepareforsgue函数中进行以下更改

if let cell = sender as? UITableViewCell, text = cell.textLabel?.text {
   otherViewController.CurrentClass = text
}

大概您在表视图的某个位置安装了一个数组中的文本。您应该将所选单元格的索引记录到didSelectRowAtIndexPath中的实例变量中，然后使用该变量在prepareForSegue方法中获取表中该项的字符串

大概是这样的：

override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath){
  let selectedCell = tableView.cellForRowAtIndexPath(indexPath)! as UITableViewCell
  performSegueWithIdentifier("TVtoVCSegue", sender: selectedCell)        
}

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
  if segue.identifier == "TVtoVCSegue" {
  let otherViewController = segue.destinationViewController as! TTDetailCntr
  otherViewController.CurrentClass = String(sender!) as String
}

cell.textLabel?.text

override func tableView(
  tableView: UITableView, 
  didSelectRowAtIndexPath indexPath: NSIndexPath)
{
  //You would need to create the instance var cellIndex
  self.cellIndex = indexPath.row
  let selectedCell = tableView.cellForRowAtIndexPath(indexPath)! as UITableViewCell
  performSegueWithIdentifier("TVtoVCSegue", sender: selectedCell)
}

override func prepareForSegue(segue: UIStoryboardSegue, 
  sender: AnyObject?) 
{
  if segue.identifier == "TVtoVCSegue" 
  {
    //This code assumes that myModel is an array of structs. 
    //Change this code to fit your data model 
    //(should be the same code you use to set the text in the cell.)
    let stringToPass = myModel[self.cellIndex].stringValue
    let otherViewController = segue.destinationViewController 
      as! TTDetailCntr
    otherViewController.CurrentClass = stringToPass
  }
}

虽然将模型数据存储在表视图单元格中是一种糟糕的设计。最好从模型对象获取数据并传递出去。@Duncac我非常同意，但我认为这可能超出了他的问题范围。@Duncac我知道，但一旦我的项目开始工作，我就会开始改进代码设计。“一旦我的项目开始工作，我就会开始改进代码设计。”这不是设计，这是一个意大利面条代码的配方。@KarlKivi如果这回答了您的问题，您不需要任何帮助，请不要忘记将其作为答案接受。好的，这段代码正常，但viewController加载了两次？我读到我不能同时实现didselectrowatinexpath和prepareforsgue函数，我必须只实现prepareforsgue并将所有代码放在那里。我应该再问一个问题还是你能帮我@邓肯
