How to pass data from all TableViewCell to CollectionView in Swift3
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.
class tableViewController: UIViewController, UITableViewDataSource,UITableViewDelegate {
@IBOutlet var nameText: UITextField!
@IBOutlet var tableView: UITableView!
var shop = Int()
var namevalue = [String]()
var phoneValue = String()
var emailValue = String()
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) {
let indexPath = tableView.indexPathForSelectedRow //optional, to get from any UIButton for example
for _ in 0..<shop {
let currentCell = tableView.cellForRow(at: indexPath!)! as! myTableViewCell
print(currentCell.self.nameText.text as Any)
}
let currentCell = tableView.cellForRow(at: indexPath!)! as! myTableViewCell
print(currentCell.self.emailText.text as Any)
namevalue.append(currentCell.nameText.text!)
// namevalue = [currentCell.nameText.text!]
phoneValue = currentCell.phoneText.text!
emailValue = currentCell.emailText.text!
genderValue = currentCell.genderText.text!
@IBAction func submitButton(_ sender: Any) {
let mainController : CollectionViewController = CollectionViewController(nibName: "CollectionViewController", bundle: nil)
mainController.getShop = shop+1
mainController.getName = namevalue
mainController.getPhone = phoneValue
mainController.getEmail = emailValue
mainController.getGender = genderValue
self.navigationController?.pushViewController(mainController, animated: true)
// self.present(mainController, animated: true, completion: nil)
}
@IBAction func Select(_ sender: Any) {
isSelectAll = true;//on button action
print(namevalue)
self.tableView.reloadData()//on button action
}

I have an idea for your problem.
Step 1 : Create new struct to save information.
struct Information {
var name: String
var phone: String
var email: String
var gender: String
init(name: String, phone: String, email: String, gender: String) {
self.name = name
self.phone = phone
self.gender = gender
self.email = email
}
}
Step 2 : In class tableViewController , create new variable:
var formData: [Information] = []
Step 3 : Each time user enter one form at cell in tableView:
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)
Step 4: In class CollectionViewController, declare new variable:
var formData: [Information] = []
Step 5: Create a header for collectionView:
| Name | Phone | Email | Gender |
Step 6: Each cell in collectionView:
| formData[indexPath].name | formData[indexPath].name | formData[indexPath].name | formData[indexPath].name |
Step 7 :
@IBAction func submitButton(_ sender: Any) {
mainController.formData = formData.
// do somethings
...
}
I don't know why you need a lot submit buttons to create many controllers, but let try my idea.
