如何将数据从所有TableViewCell传递到Swift3中的CollectionView

我已经创建了动态表单，用户输入了多个表单，并为此创建了表格单元格。提交所有表单后，所有细节都应显示在excel formate中，因为我已创建集合视图，但问题是唯一选中的单元格值正在打印。如何将数据从所有TableViewCell传递到Swift3中的CollectionView

class tableViewController: UIViewController, UITableViewDataSource,UITableViewDelegate { 

    @IBOutlet var nameText: UITextField! 
    @IBOutlet var tableView: UITableView! 

    var shop = Int()

    var genderValue = String() 
    var isSelectAll = false; 
    public func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int 

    { 
     return shop 
    } 


    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 

     if(isSelectAll==true) 
     { 
      cell.backgroundColor = UIColor.blue; 
     } 
     else 
     { 
      cell.backgroundColor = UIColor.white; 
     } 
     cell.formNoLabel.text = j 

     for _ in 0..<shop{ 

     print(cell.nameLabel.text as Any) 
     } 

     if indexPath.section == 0{ 
      if indexPath.row == 0{ 
       print(cell.emailText.text as Any) 

      } 
     } 

     for shop in 0..<(indexPath.count){ 

      let thisPath = indexPath[shop] 
      print(thisPath as Any) 
     } 

       return cell 
    }  public func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {

说真的。你应该保持你的代码清洁。 – javimuu

@javimuu我认识的人！因为我有很多方法可以解决这个问题。你能帮我吗？我可以寄给你所有的代码。 – ViralRathod

我对你的问题的想法。

步骤1：创建新的结构来保存信息。

步骤2：在class tableViewController，创建新的变量：

var formData: [Information] = []

步骤3：每次用户在的tableView在细胞进入一种形式：

let name = cell.nameText.text! 
let phone = cell.phoneText.text! 
let email = cell.emailText.text! 
let gender = cell.genderText.text! 

data = Information(name: name, phone: phone, email: email, gender: gender) 

formData.append(data)

步骤4：在类CollectionViewController，声明新的变量：

var formData: [Information] = []

步骤5：为的CollectionView创建标题：

|名称|电话|电子邮件|性别|

步骤6：在的CollectionView每个小区：

步骤7：

@IBAction func submitButton(_ sender: Any) { 
    mainController.formData = formData. 
    // do somethings 
... 
}

我不知道为什么你需要大量的提交按钮创建多个控制器，但让尝试我的想法。

感谢您的帮助thx。我在tableView控制器中创建了第二个按钮，用于选择所有行 – ViralRathod

我可以收到您的电子邮件，因此我向您发送所有代码，然后您可以得到确切的问题？ – ViralRathod
