Dose anyone know how I can make a user sign up with parse in Swift Xcode 6.4?
I Have searched everything and can't find one that works.
I Tried this code but it did not work.
It said:
Use of unresolved identifier PFUser
import UIKit
class SignupViewController: UIViewController {
#IBOutlet var usernameTextField: UITextField!
#IBOutlet var passwordTextField: UITextField!
#IBOutlet var emailTextField: UITextField!
#IBOutlet var messageLabel: UILabel!
#IBAction func loginVerifyButton(sender: AnyObject) {
var usrEntered = usernameTextField.text
var pwdEntered = passwordTextField.text
var emlEntered = emailTextField.text
if usrEntered != "" && pwdEntered != "" && emlEntered != "" {
// If not empty then yay, do something
} else {
WrongInfo()
}
}
func userSignUp() {
var user = PFUser()
user.username = usrEntered
user.password = pwdEntered
user.email = emlEntered
}
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
/*
// MARK: - Navigation
// In a storyboard-based application, you will often want to do a little preparation before navigation
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
// Get the new view controller using segue.destinationViewController.
// Pass the selected object to the new view controller.
}
*/
func WrongInfo(){
var WrongInfo:UIAlertView = UIAlertView(title: "ALL FEILDS REQUIRED", message: "Please use all feilds!", delegate: self, cancelButtonTitle: "ok")
}
}
You need to import Parse , in Appdelegate.swift file! if still getting same error import Parse in signup view controller too
You have to create your own view and then implement it/segue users to it based on the users current status. If they click your sign up button segue them to a custom view and then act accordingly. You would sign them up with a function similar to what you have offered already in your question:
func myMethod() {
var user = PFUser()
user.username = "myUsername"
user.password = "myPassword"
user.email = "email#example.com"
// other fields can be set just like with PFObject
user["phone"] = "415-392-0202"
user.signUpInBackgroundWithBlock {
(succeeded: Bool, error: NSError?) -> Void in
if let error = error {
let errorString = error.userInfo?["error"] as? NSString
// Show the errorString somewhere and let the user try again.
} else {
// Hooray! Let them use the app now.
}
}
You essentially could use the same view you already have since your fields are identical but call different methods depending on the button they select.

im attempting to add user data via a create account view controller which contains all UITextFields (password, confirm password, first name, last name, phone number). when the create account button is tapped, the users email shows up in the authentication section on the firebase website but the user information from the first name, last name and phone number text fields are not passed into the database. I'm new to iOS development and have never used firebase so im unsure what the issue is. the app runs without crashing.
below is my Create Account view controller
thanks in advance
import UIKit
import FirebaseAuth
import QuartzCore
import FirebaseDatabase
import Firebase
class CreateAccount: UIViewController {
var refUsers: DatabaseReference!
#IBOutlet weak var emailTextField: UITextField!
#IBOutlet weak var passwordTextField: UITextField!
#IBOutlet weak var confirmPasswordTextField: UITextField!
#IBOutlet weak var firstNameTextField: UITextField!
#IBOutlet weak var lastNameTextField: UITextField!
#IBOutlet weak var phoneNumberTextField: UITextField!
#IBOutlet weak var alreadyHaveAccountLabel: UILabel!
#IBAction func loginButtonTapped(_ sender: Any) {
performSegue(withIdentifier: "showLoginScreen", sender: self)
}
override func viewDidLoad() {
super.viewDidLoad()
self.refUsers = Database.database().reference().child("Users");
// Do any additional setup after loading the view.
}
override func viewDidAppear(_ animated: Bool) {
if Auth.auth().currentUser != nil {
print("success")
self.presentMainScreen()
}
}
#IBAction func createAccountTapped(_ sender: Any) {
if let email = emailTextField.text, let password = passwordTextField.text {
Auth.auth().createUser(withEmail: email, password: password, completion:{ user, error in
if let firebaseError = error {
print(firebaseError.localizedDescription)
return
} else {
self.addUser()
print("this is the first name:", self.firstNameTextField.text!)
print("this is the last name:", self.lastNameTextField.text!)
print("this is the phone number" , self.phoneNumberTextField.text!)
print("success")
self.presentMainScreen()
}
})
}
}
func addUser(){
let key = refUsers.childByAutoId().key
let user = ["id":key,
"FirstName":firstNameTextField.text! as String,
"LastName":lastNameTextField.text! as String,
"PhoneNumber":phoneNumberTextField.text! as String
]
refUsers.child(key).setValue(user)
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
/*
// MARK: - Navigation

}
*/
func presentMainScreen(){
let mainstoryboard = UIStoryboard(name: "Main", bundle: nil)
let mainTabController = mainstoryboard.instantiateViewController(withIdentifier: "MainTabController") as! MainTabController
mainTabController.selectedViewController = mainTabController.viewControllers?[0]
self.present(mainTabController, animated: true, completion: nil)
//let storyboard:UIStoryboard = UIStoryboard(name:"Main", bundle:nil)
//let loggedInVC:LoggedInVC = storyboard.instantiateViewController(withIdentifier: "LoggedInVC") as! LoggedInVC
//self.present(loggedInVC, animated: true, completion: nil)
}
}
Try this:
Instead of set value use update value
let childUpdates = ["/user/\(key)": user]
refUser.updateChildValues(childUpdates)
Hope this helps :)
I can't seem to get this to work. The database portion works and I'm getting user info as intended in the database, but it is not creating users in Firebase Auth. For the following code, it printed "can't register."
Can someone please tell me what I'm doing wrong?
import UIKit
import Firebase
import FirebaseAuth
class AddUserTableViewController: UITableViewController, UITextFieldDelegate {
#IBOutlet weak var firstNameTextField: UITextField!
#IBOutlet weak var emailTextField: UITextField!
#IBAction func saveUserButton(_ sender: Any) {
let ref: FIRDatabaseReference!
ref = FIRDatabase.database().reference()
FIRAuth.auth()?.createUser(withEmail: emailTextField.text!, password: "pass", completion: { (user, error) in
if error != nil {
print ("Can't Register")
}
else {
print ("I don't know what this means")
}
})
ref?.child("Users").childByAutoId().setValue(["First Name": self.firstNameTextField.text, "Email": self.emailTextField.text])
}
Just include Firebase, you don't need to include FirebaseAuth as well on each page.
Here's my working code for FireBase login, I did this from a Youtube tutorial a few weeks ago.
import UIKit
import Firebase
class LoginController: UIViewController {
#IBOutlet weak var menuButton:UIBarButtonItem!
#IBOutlet weak var signinSelector: UISegmentedControl!
#IBOutlet weak var signinLabel: UILabel!
#IBOutlet weak var emailTextField: UITextField!
#IBOutlet weak var passwordTextField: UITextField!
#IBOutlet weak var signinButton: UIButton!
var isSignIn:Bool = true
override func viewDidLoad() {
super.viewDidLoad()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
#IBAction func signinSelectorChanged(_ sender: UISegmentedControl) {
//Flip the boolean true to false
isSignIn = !isSignIn
//Check the boolean and set the buttons and labels
if isSignIn {
signinLabel.text = "Sign In"
signinButton.setTitle("Sign In", for: .normal)
}
else {
signinLabel.text = "Register"
signinButton.setTitle("Register", for: .normal)
}
}
#IBAction func signinButtonTapped(_ sender: UIButton) {
//Do some form validation on email and password
if let email = emailTextField.text, let pass = passwordTextField.text
{
//Check if it's signed or register
if isSignIn {
//Sign in the user with Firebase
Auth.auth().signIn(withEmail: email, password: pass, completion: { (user, error) in
//Check that user isn't nil
if let u = user {
//User is found, goto home screen
self.performSegue(withIdentifier: "goToHome", sender: self)
}
else{
//Error: Check error and show message
}
})
}
else {
//Register the user with Firebase
Auth.auth().createUser(withEmail: email, password: pass, completion: { (user, error) in
//Check that user isn't NIL
if let u = user {
//User is found, goto home screen
self.performSegue(withIdentifier: "goToHome", sender: self)
}
else {
//Check error and show message
}
})
}
}
}
override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
//Dismiss the keyboard when the view is tapped on
emailTextField.resignFirstResponder()
passwordTextField.resignFirstResponder()
}
}
Below is the code, hope anyone can help me solve the Use of unresolved identifier 'SignUp' problem:
#IBOutlet var UsernameTextField: UITextField!
#IBOutlet var PasswordTextField: UITextField!
#IBOutlet var EmailTextField: UITextField!
#IBAction func LogIn(sender: AnyObject) {
}
#IBAction func Signup(sender: AnyObject) {
SignUp() //Error is here.
}
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
func SignUp(){
var user = PFUser()
user.username = UsernameTextField.text
user.password = PasswordTextField.text
user.email = EmailTextField.text
}
let user = PFUser()
user.username = "Name:"
user.password = "Pass:"
user.email = "Email:"
user.signUpInBackgroundWithBlock { (success: Bool, error: NSError?) -> Void in
if error == nil {
// Hooray! Let them use the app now.
} else {
// Examine the error object and inform the user.
}
}
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
Make the function declaration and call start with a lower case s.
It's also worth noting you should name stuff so it's clear what is it.
#IBAction func signUpButton(sender: AnyObject) {
signUp() // Calling signUp function here that is declared below.
}
func signUp(){
// Do sign up stuff.
}
I'm new in this website, and I already know that it helps me a LOT in coding, so thanks to the founder of this website and to the questioners and the answerers and everyone else :D
Still, one problem I have though. I have this 'Missing Argument for Parameter #1 in call' error. Its really annoying me, I'm trying to make an app, and for how much time I put into this app, I don't want to delete it. Please.
So here is the code:
class ViewController: UIViewController {
#IBOutlet var UsernameTextField: UITextField!
#IBOutlet var PasswordTextField: UITextField!
#IBOutlet var EmailTextField: UITextField!
#IBAction func LogIn(sender: AnyObject) {
}
#IBAction func SignUp(sender: AnyObject) {
SignUp() //The error is here
}
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
func SignUp(){
var user = PFUser()
user.username = UsernameTextField.text
user.password = PasswordTextField.text
user.email = EmailTextField.text
}
let user = PFUser()
user.username = "Name:"
user.password = "Pass:"
user.email = "Email:"
user.signUpInBackgroundWithBlock { (success: Bool, error: NSError?) -> Void in
if error == nil {
// Hooray! Let them use the app now.
} else {
// Examine the error object and inform the user.
}
}
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
You've got two functions with the same name, you should rename one of them!
First function:
#IBAction func SignUp(sender: AnyObject)
Second function:
func SignUp()
The reason you get the error is because the compiler is trying to use your first function rather than the second one, so the easiest way to fix it is to change the name of one of the functions.
After the user logs in SUCCESSFULLY, I need to switch view controllers to the timeline section of my app, this is also going to be a tab bar view controller with 5 different tabs at the bottom. Here is the code I have so far, it works and is connected to the parse database I have setup.
import UIKit
import Parse
class LoginViewController: UIViewController {
#IBOutlet var usernameField: UITextField!
#IBOutlet var passwordField: UITextField!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
#IBAction func loginTapped(sender: AnyObject) {
let username = usernameField.text
let password = passwordField.text
PFUser.logInWithUsernameInBackground(username, password:password) {
(user: PFUser?, error: NSError?) -> Void in
if user != nil {
println("Success")
} else {
var loginError:UIAlertView = UIAlertView(title: "Invalid Login", message: "I did not recognize your credentials. Try again?", delegate: self, cancelButtonTitle: "Dismiss")
loginError.show()
}
}
}
#IBAction func closeTapped(sender: AnyObject) {
dismissViewControllerAnimated(true, completion: nil)
}
}
In the line println("sucessful"), instead of printing out the sucessful login I need to switch to their timeline home (the tab bar view controller).
Use a segue to transition to new view controller if the login was successful:
if user != nil {
self.performSegueWithIdentifier("successfulLoginPage", sender: self)
}
