如何将每个tableViewcell数据发送到swift3中的collectionview

Question

I have created dynamic forms, user enter number of forms, and i have created table cell for that. After submitting the all forms, all details should show in excel formate, for that i have created collection view but issue is that the only selected cell value is printing. I use this for collectionView

            }

            return contentCell
     }}}}

1.I Entered number of form i want

2. no of forms displayed and i entered all different values for all different forms

3.But what happening is only one form details are printing

Answer 1

You shouldn't get your data in public func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell

Because when you scroll up / down, this func will call again and again.

 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

}

And in myTableViewCell class, you should change to

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
    }
}

}

Remember change struct Information to class Information
