I am trying to implement FIrebase UI phone number authentication, but the delegate method is not called after the phone number is verified. Any reason why?
class Login: UIViewController, FUIAuthDelegate {
let authUI = FUIAuth.defaultAuthUI()
override func viewDidAppear(_ animated: Bool) {
let phoneProvider = FUIPhoneAuth(authUI: authUI!)
authUI!.isSignInWithEmailHidden = true
authUI!.providers = [phoneProvider]
phoneProvider.signIn(withPresenting: self, phoneNumber: nil)
}
//this method does not work either... it is not called
func authUI(_ authUI: FUIAuth, didSignInWith authDataResult: AuthDataResult?, error: Error?) {
print("user is \(authDataResult!.user.email)")
print("err is \(error?.localizedDescription)")
guard error == nil else {
print(error)
return
}
}
}
I had forgotten to assign self as the delegate to authUI
override func viewDidAppear(_ animated: Bool) {
authUI?.delegate = self
let phoneProvider = FUIPhoneAuth(authUI: authUI!)
authUI!.isSignInWithEmailHidden = true
authUI!.providers = [phoneProvider]
phoneProvider.signIn(withPresenting: self, phoneNumber: nil)
}

Im using event kit to create a reminder, but when I press add or cancel the window does not close. if I go into the calendars app I can see the item in there. I've tried adding "editviewDelegate = self" but I always get an error saying "Cannot assign value of type 'ViewController?' to type 'EKEventEditViewDelegate"
import UIKit
import EventKit
import EventKitUI
class ViewController: UIViewController, EKEventViewDelegate {
func eventViewController(_ controller: EKEventViewController, didCompleteWith action: EKEventViewAction) {
controller.dismiss(animated: true, completion: nil)
}
let store = EKEventStore()
override func viewDidLoad() {
super.viewDidLoad()
navigationItem.rightBarButtonItem = UIBarButtonItem(barButtonSystemItem: .add, target: self, action: #selector(addnew))
}
#objc func addnew() {
store.requestAccess(to: .event) { [weak self] success, error in
if success, error == nil {
DispatchQueue.main.async {
guard let store = self?.store else {return}
let othervc = EKEventEditViewController()
othervc.eventStore = store
othervc.event = EKEvent(eventStore: store)
self?.present(othervc, animated: true, completion: nil)
}
}
}
}
I have defined a listener in the viewWillAppear() function, and am trying to remove/detach it in the viewWillDisappear function. However, I am unable to access the listener in the viewWillDisappear() function, so am unable to use .remove() to detach it.
My code:
override func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(true)
let db = Firestore.firestore()
let docRef = db.collection("collection").document("document")
let listener = docRef.addSnapshotListener { (querySnapshot, errur) in
....
}
}
override func viewWillDisappear(_ animated: Bool) {
listener.remove() //ERROR: Use of unresolved identifier 'listener'
}
I realise that the error is because "listener" was defined in another scope, but how can I still access it to remove it in the viewWillDisappear() ?
private var listener: ListenerRegistration?
override func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(true)
let db = Firestore.firestore()
let docRef = db.collection("collection").document("document")
listener = docRef.addSnapshotListener { (querySnapshot, errur) in
// ....
}
}
override func viewWillDisappear(_ animated: Bool) {
// always call super.viewWillDisappear also.
super.viewWillDisappear(animated)
listener.remove() //ERROR: Use of unresolved identifier 'listener'
listener = nil
}
I'm implementing a mail controller in my app but I can't figure out why it won't close when clicking save draft or delete draft. The window gets stuck on the email screen and I can't click "Cancel" a second time either.
#IBAction func emailButtonTapped(_ sender: UIButton) {
guard MFMailComposeViewController.canSendMail() else {
if !MFMailComposeViewController.canSendMail() {
print("Can not send email")
return
}
return
}
func mailComposeController(_ controller: MFMailComposeViewController, didFinishWith result: MFMailComposeResult, error: Error?) {
dismiss(animated: true, completion: nil)
}
let mailComposer = MFMailComposeViewController()
mailComposer.mailComposeDelegate = self
mailComposer.setToRecipients(["example#example.com"])
mailComposer.setSubject("Look at this")
mailComposer.setMessageBody("Hello, this is an email from the app I made.", isHTML: false)
present(mailComposer, animated: true, completion: nil)
}
I successfully fixed the issue, and it was a pretty stupid one!
Some code was outside the emailButtonTapped func:
#IBAction func emailButtonTapped(_ sender: UIButton) {
//guard MFMailComposeViewController.canSendMail() else {
if !MFMailComposeViewController.canSendMail() {
print("Can not send email")
return
}
let mailComposer = MFMailComposeViewController()
mailComposer.mailComposeDelegate = self
mailComposer.setToRecipients(["example#example.com"])
mailComposer.setSubject("Look at this")
mailComposer.setMessageBody("Hello, this is an email from the app I made.", isHTML: false)
present(mailComposer, animated: true, completion: nil)
}
func mailComposeController(_ controller: MFMailComposeViewController, didFinishWith result: MFMailComposeResult, error: Error?) {
dismiss(animated: true, completion: nil)
}
Swift 4
// MARK: - SEND EMAIL BUTTON
#IBAction func SendEmailButt(_ sender: AnyObject) {
// This string containes standard HTML tags, you can edit them as you wish
let messageStr = "Hello,"
let mailComposer = MFMailComposeViewController()
mailComposer.mailComposeDelegate = self
mailComposer.setSubject("Title")
mailComposer.setMessageBody(messageStr, isHTML: true)
if MFMailComposeViewController.canSendMail() { present(mailComposer, animated: true, completion: nil)
} else {
print("Your device cannot send emails. Please configure an email address into Settings -> Mail, Contacts, Calendars.")
}
}
// Email delegate
func mailComposeController(_ controller: MFMailComposeViewController, didFinishWith result: MFMailComposeResult, error: Error?) {
var resultMess = ""
switch result.rawValue {
case MFMailComposeResult.cancelled.rawValue:
resultMess = "Mail cancelled"
case MFMailComposeResult.saved.rawValue:
resultMess = "Mail saved"
case MFMailComposeResult.sent.rawValue:
resultMess = "Thanks for contacting us!\nWe'll get back to you asap."
case MFMailComposeResult.failed.rawValue:
resultMess = "Something went wrong with sending Mail, try again later."
default:break
}
// Show email result alert
print(resultMess)
dismiss(animated: true, completion: nil)
}
Can you try this once instead:
func mailComposeController(controller: MFMailComposeViewController, didFinishWithResult result: MFMailComposeResult, error: NSError?) {
// Dismiss the mail compose view controller.
controller.dismissViewControllerAnimated(true, completion: nil)
}
Check the following Code.
#IBAction func sendEmailButtonTapped(sender: AnyObject) {
let mailComposeViewController = configuredMailComposeViewController()
if MFMailComposeViewController.canSendMail() {
self.presentViewController(mailComposeViewController, animated: true, completion: nil)
} else {
self.showSendMailErrorAlert()
}
}
func configuredMailComposeViewController() -> MFMailComposeViewController {
let mailComposerVC = MFMailComposeViewController()
mailComposerVC.mailComposeDelegate = self
mailComposerVC.setToRecipients([])
mailComposerVC.setSubject("Sending In-App Email")
mailComposerVC.setMessageBody("Sending Email through your app in Swift", isHTML: false)
return mailComposerVC
}
func showSendMailErrorAlert() {
let sendMailErrorAlert = UIAlertView(title: "Could Not Send Email", message: "Your device could not send Email. Please check Email configuration and try again.", delegate: self, cancelButtonTitle: "OK")
sendMailErrorAlert.show()
}
// MFMailComposeViewControllerDelegate Method
func mailComposeController(controller: MFMailComposeViewController!, didFinishWithResult result: MFMailComposeResult, error: NSError!) {
controller.dismissViewControllerAnimated(true, completion: nil)
}
I am trying to add a send email button to a Sprite Kit game. I can get the email dialog to show up. But if I hit cancel, the app will crash or do nothing. If I hit send, the email will send, but the dialog stays. I cannot get the mailComposeController function to fire...please help!
Code:
import Foundation
import UIKit
import MessageUI
class MailViewController: UIViewController, MFMailComposeViewControllerDelegate {
let systemVersion = UIDevice.currentDevice().systemVersion
let devicemodel = UIDevice.currentDevice().model
let appVersion = NSBundle.mainBundle().infoDictionary?["CFBundleShortVersionString"] as! String
let appBuild = NSBundle.mainBundle().infoDictionary?["CFBundleVersion"] as! String
let myrootview2 = UIApplication.sharedApplication().keyWindow?.rootViewController
let mailComposerVC = MFMailComposeViewController()
override func viewDidLoad() {
super.viewDidLoad()
}
func sendEmailButtonTapped(sender: AnyObject) {
let mailComposeViewController = configuredMailComposeViewController()
if MFMailComposeViewController.canSendMail() {
self.view.window?.rootViewController = mailComposerVC
print("This is the rootview2: \(myrootview2)")
myrootview2!.presentViewController(mailComposeViewController, animated: true, completion: nil)
} else {
self.showSendMailErrorAlert()
}
}
func configuredMailComposeViewController() -> MFMailComposeViewController {
var msgbody: String
mailComposerVC.mailComposeDelegate = self
msgbody = "\n\nDevice: \(devicemodel)\niOS Version: \(systemVersion)\nApp Version: \(appVersion)\nApp Build Number: \(appBuild)\n"
mailComposerVC.setToRecipients(["test1#test.com"])
mailComposerVC.setSubject("test subject")
mailComposerVC.setMessageBody(msgbody, isHTML: false)
//print(mailComposerVC)
return mailComposerVC
}
func showSendMailErrorAlert() {
let sendMailErrorAlert = UIAlertView(title: "Could Not Send Email", message: "Your device could not send e-mail. Please check e-mail configuration and try again.", delegate: self, cancelButtonTitle: "OK")
sendMailErrorAlert.show()
}
// THIS DOESN'T GET CALLED WHEN SENDING OR CANCELLING EMAIL!
func mailComposeController(controller: MFMailComposeViewController, didFinishWithResult result: MFMailComposeResult, error: NSError?) {
let test1 = result.rawValue
print(test1)
print(controller)
print(self)
print(myrootview2)
}
The issue is you are making the mailVC as the root view, you have to present it on your view like given below
#IBAction func sendEmailButtonTapped(sender: AnyObject) {
let mailComposeViewController = configuredMailComposeViewController()
if MFMailComposeViewController.canSendMail() {
self.presentViewController(mailComposeViewController, animated: true, completion: nil)
} else {
self.showSendMailErrorAlert()
}
}
func mailComposeController(controller: MFMailComposeViewController!, didFinishWithResult result: MFMailComposeResult, error: NSError!) {
controller.dismissViewControllerAnimated(true, completion: nil)
}
I have used the code below to create my GameCenter page in my app. However, I haven't been able to connect the leaderboard that I created on iTunes Connect to my code, so the app just produces a blank leaderboard page. How do I connect my Itunes Connect leaderboard to my code, and how do I make the app such that it places your score on the leaderboard, as right now the leaderboard is empty.
Here is the code I used:
override func viewDidAppear(animated: Bool) {
//check user is logged into GameCenter
var localPlayer = GKLocalPlayer.localPlayer()
localPlayer.authenticateHandler = {(viewController : UIViewController!, error : NSError!) -> Void in
if ((viewController) != nil) {
self.presentViewController(viewController, animated: true, completion: nil)
} else {
println((GKLocalPlayer.localPlayer().authenticated))
}
}
//display leaderboard
func showLeaderboard() {
var gcViewController: GKGameCenterViewController = GKGameCenterViewController()
gcViewController.gameCenterDelegate = self
gcViewController.viewState = GKGameCenterViewControllerState.Leaderboards
gcViewController.leaderboardIdentifier = "MyLeaderboard"
self.showViewController(gcViewController, sender: self)
self.navigationController?.pushViewController(gcViewController, animated: true)
}
//take leaderboard away
func gameCenterViewControllerDidFinish(gcViewController: GKGameCenterViewController!) {
self.dismissViewControllerAnimated(true, completion: nil)
}
How do I connect my Itunes Connect leaderboard to the app, and what code do I use to upload one's score to the leaderboard?
Firstly add the GKGameCenterControllerDelegate to your class:
class viewController: UIViewController, GKGameCenterControllerDelegate {
...
}
This is the code you need to use to authenticate the player:
func login() {
println("Game Center Login Called")
let localPlayer = GKLocalPlayer.localPlayer()
// Handle the authentication
localPlayer.authenticateHandler = {(Home: UIViewController!, error: NSError!) -> Void in
if Home != nil {
println("Authentication is being processed.")
self.presentViewController(Home, animated: true, completion: nil)
} else {
println("Player has been successfully authenticated.")
}
}
}
This is the code you should use to show up the leaderboard:
func showLeaderboard() {
var gcViewController: GKGameCenterViewController = GKGameCenterViewController()
gcViewController.gameCenterDelegate = self
gcViewController.viewState = GKGameCenterViewControllerState.Leaderboards
gcViewController.leaderboardIdentifier = "YOUR_LEADERBOARD_ID"
self.showViewController(gcViewController, sender: self)
self.presentViewController(gcViewController, animated: true, completion: nil)
}
This code is needed when the user taps on "Done".
func gameCenterViewControllerDidFinish(gcViewController: GKGameCenterViewController!)
{
self.dismissViewControllerAnimated(true, completion: nil)
}
You can call the authentication method login() in the viewDidLoad method:
override func viewDidLoad() {
super.viewDidLoad()
login()
...
}
Show up the leaderboard when the user taps on a button
#IBAction func button(sender: AnyObject) {
showLeaderboard()
}
If you want to submit the best score:
if GKLocalPlayer.localPlayer().authenticated {
println("I have submitted the score to Game Center")
let gkScore = GKScore(leaderboardIdentifier: "Best_Score")
gkScore.value = Int64(bestScore)
GKScore.reportScores([gkScore], withCompletionHandler: ( { (error: NSError!) -> Void in
if (error != nil) {
// handle error
println("Error: " + error.localizedDescription);
} else {
println("Score reported: \(gkScore.value)")
}
}))
}
