嗨！我在UITableView上遇到问题。我将PickerView添加到我的textField的部分行中，如下面的代码所示。实际上，pickerView将添加到indexPath.row中的单元格，但不是每个部分。所以这让我今天早上坚持下去。对不起，我的英语不好。特别感谢您的解决方案。TableView中的每个单元格上的数据重复

这里是我的代码：

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell { 
    let data = (self.tableItems[indexPath.section].value?[indexPath.row])! 
    let identifier : String = data["CELL_IDENTIFIER"]!! 
    let cell = tableView.dequeueReusableCell(withIdentifier: identifier) 
    if cell is QuotationHeaderInSectionCell{ 
     let headerCell = cell as! QuotationHeaderInSectionCell 
     headerCell.lblHeaderInSectionTitle.text = data["TEXT_LABEL"]!! 
    }else if cell is QuotationItemCell{ 
     let itemCell = cell as! QuotationItemCell 
     itemCell.lblCellTitle.text = data["TEXT_LABEL"]!! 
     switch indexPath.section { 
     case 0: 
      switch indexPath.row { 
      case 1: 
       self.initInputViewForTextField(sender: itemCell.textFieldCell, inputView: titlePickerView) 
       break 
      case 4: 
       self.initInputViewForTextField(sender: itemCell.textFieldCell, inputView: genderPickerView) 
       break 
      case 10: 
       self.initInputViewForTextField(sender: itemCell.textFieldCell, inputView: provincePickerView) 
       break 
      case 11: 
       self.initInputViewForTextField(sender: itemCell.textFieldCell, inputView: districtPickerView) 
       break 
      case 12: 
       self.initInputViewForTextField(sender: itemCell.textFieldCell, inputView: communePickerView) 
       break 
      case 13: 
       self.initInputViewForTextField(sender: itemCell.textFieldCell, inputView: villagePickerView) 
       break 
      default: 
       break 
      } 
      break 
     case 1: 
      switch indexPath.row { 
      case 0: 
       self.initInputViewForTextField(sender: itemCell.textFieldCell, inputView: assetMakePickerView) 
       break 
      case 1: 
       self.initInputViewForTextField(sender: itemCell.textFieldCell, inputView: assetRangePickerView) 
       break 
      case 2: 
       self.initInputViewForTextField(sender: itemCell.textFieldCell, inputView: assetModelPickerView) 
       break 
      case 3: 
       self.initInputViewForTextField(sender: itemCell.textFieldCell, inputView: assetColorPickerView) 
       break 
      default: 
       break 
      } 
     case 2: 
      if indexPath.row == 0 { 
       self.initInputViewForTextField(sender: itemCell.textFieldCell, inputView: dealerPickerView) 
      } 
      break 
     case 3: 
      switch indexPath.row { 
      case 0: 
       self.initInputViewForTextField(sender: itemCell.textFieldCell, inputView: financeProductPickerView) 
       break 
      case 1: 
       self.initInputViewForTextField(sender: itemCell.textFieldCell, inputView: advPaymentPercentPickerView) 
       break 
      case 3: 
       self.initInputViewForTextField(sender: itemCell.textFieldCell, inputView: assetColorPickerView) 
       break 
      default: 
       break 
      } 
      break 
     default: 
      break 
     } 
    }else if cell is QuotationCommentCell{ 
     let commentCell = cell as! QuotationCommentCell 
     commentCell.textViewComment.text = data["TEXT_LABEL"]!! 
    }else if cell is DocumentTableViewCell{ 
     let documentCell = cell as! DocumentTableViewCell 
    } 
    return cell! 
}

回答：

第二个想法我还不如给一个正式的答案后。

您可以将textField添加到具有storyboard或单元格子类的init函数的单元格的原型中。

然后在视图控制器中有一个indexPath属性来知道当它出现时你正在填充哪个选择器 - 我通常将它命名为currentIndexPath，并将它传递给单元格。

将委托设置为拥有该选取器的textField的单元格。另外，在单元格子类中创建一个数组来保存选择器的数据。

在cellForRowAt你的代码看起来像

if cell is QuotationItemCell { 
    let itemCell = cell as! QuotationItemCell 
    switch indexPath.section { 
    case 0: 
     switch indexPath.row { 
     case 1,4,10,11,12,13: 
      itemCell.textField.alpha = 1 
      currentIndexPath = indexPath 
      itemCell.currentIndexPath = indexPath //Property of the cell subclass 
      itemCell.dataArray = dataDict[indexPath.row] 
      itemCell.pickerView.reloadAllComponent //If the pickerView cannot be accessed here create a method in the cell subclass to reload it. 
     default: 
      itemCell.textField.alpha = 0 
     } 
    } 
}

在UIPickerDelegate方法titleForRow可以从电池的阵列刚读。

你问实际上可能是一个字典更好的阵列

class yourViewController, UIViewController { 
    let dataDict = [4:["Male","Female"], 
        10:["Something","Else"]] //Make sure the key correspond to the row the data is in 
    var currentIndexPath:IndexPath = IndexPath() //This is suppose to be here too 
}
