【中文标题】如何在swift3中将每个tableViewcell数据发送到collectionview【英文标题】：How to send each tableViewcell data to collectionview in swift3 【发布时间】：2017-03-16 03:59:50 【问题描述】：我创建了动态表单，用户输入了表单数量，并且为此创建了表格单元格。提交所有表单后，所有详细信息都应以 excel 格式显示，因为我已经创建了集合视图，但问题是唯一选择的单元格值正在打印。 我将它用于collectionView

1.我输入了我想要的表格编号
2。没有显示的表单，我为所有不同的表单输入了所有不同的值
3.但是发生的只是一个表单细节正在打印
【问题讨论】：
嗨。您说“问题是唯一选定的单元格值正在打印”。你能显示你选择单元格时使用的代码吗 @Luan 你好，我已经发布了我的屏幕截图，所以你会有想法 @LuanTran 你能解决吗？ 当您点击提交按钮时，您是否要备份和收集数据？ 没有。我想要的是，假设我填写 3 个不同的表单并点击提交按钮，所有值都应该打印 【参考方案1】：您不应该在public func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell 中获取您的数据
因为当你向上/向下滚动时，这个函数会一次又一次地调用。
public func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell
let k = indexPath.row+1
let j:String? = String(k)
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! myTableViewCell
cell.formNoLabel.text = j
for indexPath in 0..<shop
print(String(indexPath))
if indexPath.section == 0
if indexPath.row == 0
print("THis is print 1",cell.emailText.text as Any)
var data : Information
if indexPath.row < formData.count
data = formData[indexPath.row]
else
data = Information(name: name, phone: phone, email: email, gender: gender)
formData.append(data)
cell.data = data
print("THis is print 2",formData)
//cell.nameLabel.text = Array[indexPath.row]
// cell.nameText.text = Array[indexPath.row]
return cell
在myTableViewCell 类中，您应该更改为
class myTableViewCell: UITableViewCell, UITextFieldDelegate
@IBOutlet var nameLabel: UILabel!
@IBOutlet var nameText: UITextField!
@IBOutlet var phoneText: UITextField!
@IBOutlet var emailText: UITextField!
@IBOutlet var genderText: UITextField!
@IBOutlet var formNoLabel: UILabel!
var data: Information!
didSet
nameText.text = data.name
phoneText.text = data.phone
emailText.text = data.email
genderText.text = data.gender
override func awakeFromNib()
super.awakeFromNib()
// Initialization code
nameText.delegate = self
phoneText.delegate = self
emailText.delegate = self
genderText.delegate = self
override func setSelected(_ selected: Bool, animated: Bool)
super.setSelected(selected, animated: animated)
// Configure the view for the selected state
public func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath)
// let indexPath = tableView.indexPathForSelectedRow //optional, to get from any UIButton for example
let currentCell = tableView.cellForRow(at: indexPath)! as UITableViewCell
print(currentCell.textLabel!.text!)
func textFieldDidEndEditing(_ textField: UITextField)
let text = textField.text!
if textField === nameText
data.name = text
else if textField === phoneText
data.phone = text
else if textField === emailText
data.email = text
else if textField === genderText
data.gender = text
记得把struct Information改成class Information
