How to send each tableViewcell data to collectionview in swift3 - ios

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

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
