Managing Multiple UItextFields - iphone

Question

Novice coder and I'm stuck. I have 2 UITextField on my Viewcontroller that I want passed to a UITableView when "save" is tapped. I've set both textFields to delegate.self, the problem is that the data entered in the textfields only shows up on the UITableView IF I remove 1 of the UItextFields.
I'm thinking in order to use 2 (or more) UITextFields on the same VC I must need a way besides the outlets to differentiate between them. I've seen responses about tags but I don't understand.
import UIKit
class BudgetViewController: UIViewController, UITextFieldDelegate, UINavigationControllerDelegate {
// Properties:
#IBOutlet weak var datePicker: UIDatePicker!
#IBOutlet weak var nameTextField: UITextField!
#IBOutlet weak var amountTextField: UITextField!
#IBOutlet weak var dateDisplay: UILabel!
#IBOutlet weak var saveButton: UIBarButtonItem!
var budget: Budget?
// Date picker:
let dateFormatter = NSDateFormatter()
func setDate() {
dateFormatter.dateStyle = NSDateFormatterStyle.MediumStyle
dateDisplay.text = dateFormatter.stringFromDate(datePicker.date)
}
// Navigation
// This method lets you configure a view controller before it's presented
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
if saveButton === sender {
let name = nameTextField.text ?? ""
let date = dateDisplay.text ?? ""
let amount = amountTextField.text ?? ""
// set the budget to be passed to the Controller, this code configures the meal prperty with the appropriate values before the segue executes
budget = Budget(date: date, name: name, amount: amount)
}
}
// Actions:
#IBAction func datePickerChanger(sender: AnyObject) {
setDate()
}
override func viewDidLoad() {
super.viewDidLoad()
// Handle the text field
nameTextField.delegate = self
amountTextField.delegate = self
}
// UITextFieldDelegate
func textFieldShouldReturn(textField: UITextField) -> Bool {
textField.resignFirstResponder()
return true
}
func textFieldDidEndEditing(textField: UITextField) {
}
}
import UIKit
class BudgetTableViewController: UITableViewController {
//Properties
var budgets = [Budget]()
override func viewDidLoad() {
super.viewDidLoad()
loadSampleBudgets()
}
func loadSampleBudgets() {
let budget1 = Budget(date: "8/16/2016", name: "Eyebrows", amount: "15")!
let budget2 = Budget(date: "8/28/2016", name: "Acme", amount: "59")!
let budget3 = Budget(date: "9/10/2016", name: "Wildwood", amount: "199")!
budgets += [budget1, budget2, budget3]
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
// MARK: - Table view data source
override func numberOfSectionsInTableView(tableView: UITableView) -> Int {
// #warning Incomplete implementation, return the number of sections
return 1
}
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return budgets.count
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cellIdentifier = "BudgetTableViewCell"
let cell = tableView.dequeueReusableCellWithIdentifier(cellIdentifier, forIndexPath: indexPath) as! BudgetTableViewCell
let budget = budgets[indexPath.row]
cell.dateLabel.text = budget.date
cell.nameLabel.text = budget.name
cell.amountLabel.text = budget.amount
return cell
}
#IBAction func unwindToMealList(sender: UIStoryboardSegue) {
if let sourceViewController = sender.sourceViewController as? BudgetViewController, budget = sourceViewController.budget {
//Add a new meal
let newIndexPath = NSIndexPath(forRow: budgets.count, inSection: 0)
budgets.append(budget)
tableView.insertRowsAtIndexPaths([indexPath], withRowanimation: .Bottom)
}
}

Check to see if your text fields outlets are properly linked to your storyboard. There should be a filled circle next to each IBOutlet. If you have both the code and storyboard open in XCode and hover your mouse over the circle next to each outlet, the text field should highlight on the storyboard.
If you copied and pasted the original name text field and changed it to the amount text field, it actually still might have a reference to the name outlet. You can check this by right clicking on the text field in the storyboard and see what outlets it refers to.
override func viewDidLoad() {
super.viewDidLoad()
nameTextField.delegate = self
streetTextField.delegate = self
cityTextField.delegate = self
stateTextField.delegate = self
countryTextField.delegate = self
phoneTextField.delegate = self
}
func textFieldShouldReturn(textField: UITextField) -> Bool {
if textField == nameTextField {
streetTextField.becomeFirstResponder()
}
else if textField == streetTextField {
cityTextField.becomeFirstResponder()
}
else if textField == cityTextField {
stateTextField.becomeFirstResponder()
}
else if textField == stateTextField {
countryTextField.becomeFirstResponder()
}
else if textField == countryTextField {
phoneTextField.becomeFirstResponder()
}
else if textField == phoneTextField {
nameTextField.becomeFirstResponder()
}
return true
}
This is some code I wrote to allow a user to fill in a form (pressing return to move from one field to the next), so you can definitely have multiple textFields with the same delegate.
