I wanna know when the user click button to reward them.
I made this but my question is when I click second time on play ad button my current (Currency on label) not plusing with new one it just get new 100 not (current + 100).
I just wanna to make my (Current) currency (+100).
can you guys help meee. please....
struct Keys {
static var currency = "Currency"
static var currentCurr = "CurrentCurrency"
}
class ViewController: UIViewController, GADRewardBasedVideoAdDelegate {
var currency = 0
var userDefault = UserDefaults.standard
#IBOutlet weak var currencyShower: UILabel!
override func viewDidLoad() {
super.viewDidLoad()
GADRewardBasedVideoAd.sharedInstance().load(GADRequest(), withAdUnitID: "ca-app-pub-3940256099942544/1712485313")
GADRewardBasedVideoAd.sharedInstance().delegate = self
if userDefault.string(forKey: Keys.currency) != nil {
currencyShower.text = userDefault.string(forKey: Keys.currency)
} else {
return
}
}
//
#IBOutlet weak var playAdOut: UIButton!
#IBAction func playAd(_ sender: UIButton) {
if GADRewardBasedVideoAd.sharedInstance().isReady == true {
GADRewardBasedVideoAd.sharedInstance().present(fromRootViewController: self)
} else {
print("Video Did not Load...")
}
}
func rewardBasedVideoAdDidClose(_ rewardBasedVideoAd: GADRewardBasedVideoAd) {
print("Video is Ready")
GADRewardBasedVideoAd.sharedInstance().load(GADRequest(),
withAdUnitID: "ca-app-pub-3940256099942544/1712485313")
}
func rewardBasedVideoAd(_ rewardBasedVideoAd: GADRewardBasedVideoAd, didFailToLoadWithError error: Error) {
print("Error When Loading")
}
func rewardBasedVideoAd(_ rewardBasedVideoAd: GADRewardBasedVideoAd, didRewardUserWith reward: GADAdReward) {
currency += 100
currencyShower.text = String(currency)
}
}
You could save currency value to UserDefaults and then retrieve or update it when needed example in following link: example
PS! If you don't want to save strings to userDefaults you can also save numbers.

I have successfully implemented core data and UISteppers. Every time I try to edit a saved record the UI Stepper starts over from 0. Please help me to figure put what additional code I need to retain the already edited value.
// This function adds the stepper to a field
//issue: it does not remember the score when i edit it and starts over
#IBAction func counterStepperPressed(_ sender: UIStepper) {
counterTF.text = Int(sender.value).description
}
#IBAction func pointStepperPressed(_ sender: UIStepper) {
pointTF.text = Int(sender.value).description
}
#IBAction func savingsStepperPressed(_ sender: UIStepper) {
savingsTF.text = Int(sender.value).description
}
}
I have linked core data like so:
import CoreData
class AktieViewController: UIViewController {
#IBOutlet weak var counterStepper: UIStepper!
#IBOutlet weak var pointsStepper: UIStepper!
#IBOutlet weak var savingsStepper: UIStepper!
var selectedAktie: Aktie? = nil
override func viewDidLoad()
{
super.viewDidLoad()
if(selectedAktie != nil) {
savingsTF.text = selectedAktie?.saving
counterTF.text = selectedAktie?.counter
pointTF.text = selectedAktie?.point
}
}
#IBAction func saveAction(_ sender: Any) {
let appDelegate = UIApplication.shared.delegate as! AppDelegate
let context: NSManagedObjectContext = appDelegate.persistentContainer.viewContext
if(selectedAktie == nil)
{
let entity = NSEntityDescription.entity(forEntityName: "Aktie", in: context)
let newAktie = Aktie (entity: entity!, insertInto: context)
newAktie.saving = savingsTF.text
newAktie.point = pointTF.text
newAktie.counter = counterTF.text
do {
try context.save()
aktieList.append(newAktie)
navigationController?.popViewController(animated: true)
}
catch
{
print("context save error")
}
}
I also have an edit and delete function.
This function eventually solved my question:
#IBAction func counterStepperPressed(_ sender: UIStepper) {
let initialValue=Int(counterTF.text) ?? 0
let newValue=Int(sender.value)+initialValue
counterTF.text="\(newValue)"
}
I have managed to add the following code to remember the value in the stepper.
if let value=UserDefaults.standard.value(forKey: "counterStepper") as? Double {
counterStepper.value=value counterTF.text=String(describing: value)
And in the action I have added the following code.
#IBAction func counterStepperPressed(_ sender: UIStepper) {
counterTF.text=String(describing: sender.value)
UserDefaults.standard.setValue(sender.value, forKey: "counterStepper")
NotificationCenter.default.post(Notification.init(name: Notification.Name("StepperDidChangeValue")))
}
The only issue I have is that if I edit a second item it remembers the value of the first item. Somehow it is not remembering the original value of the item.
i am making an app Redmine, i have a website with a user with pass and there are issues. But i can't understand what i should do to make authorization.
Here I have Router, Request, AuthViewController. I also wanted to ask how i have to make AuthRequest? What has to be there?
AuthViewController
import UIKit
class AuthViewController: UIViewController {
#IBOutlet weak var emailField: UITextField!
#IBOutlet weak var passwordField: UITextField!
#IBOutlet weak var signInBotton: UIButton!
override func viewDidLoad() {
super.viewDidLoad()
}
#IBAction func signInDidTap(_ sender: Any) {
login()
}
fileprivate func login(){
AuthRequest.login(email: emailField.text!, password: passwordField.text!){(user, error) in DispatchQueue.main.async {
[unowned self] in self.openIssues()
}
}
}
}
//extension AuthViewController: Router{
// func prepare() {
// Here error with 'seque' if(seque.identifier = Seque.issues.rawValue){
// print("It's OK")
// guard let controller = seque.destination as? IssuesViewController else { print("Wrong destination"); return}
// //controller.presenter = IssuesPresenter();
// }
// }
//
// func openIssues() {
// print("kek")
// }
//
//
// enum Seque: String {
// case issues = "IssuesSeque"
// }
//
//}
There is also an error in if-block in extension.
I have seen some other questions asked but I am having trouble getting it to work. I have a Mac app coded in swift and it has a Firebase login but the user types a key in that is stored on Firebase, is there a way to automatically delete that key when the user has successfully used it?
This is my database.
This is the code that is used currently.
import Cocoa
import FirebaseAuth
import FirebaseDatabase
class LoginViewController: NSViewController {
#IBOutlet weak var textUsername: NSTextField!
#IBOutlet weak var textPassword: NSSecureTextFieldCell!
#IBOutlet weak var btnLogin: NSButton!
var keyArray = \[Int64\]()
override func viewDidLoad() {
super.viewDidLoad()
}
override func viewWillAppear() {
}
func getLoginState() -> Bool{
let state = UserDefaults.standard.bool(forKey: "isRegistered")
if (state) {
return true
} else {
return false
}
}
override func viewDidAppear() {
let state = self.getLoginState()
if (state){
self.performSegue(withIdentifier: NSStoryboardSegue.Identifier(rawValue: "loginsegue"), sender: nil)
self.view.window?.close()
}
var ref: DatabaseReference!
ref = Database.database().reference()
let keyRef = ref.child("key1")
keyRef.observe(DataEventType.childAdded, with: { (snapshot) in
// let postDict = snapshot.value as? \[String : AnyObject\] ?? \[:\]
let keyStr = snapshot.value as? Int64
if let actualPost = keyStr{
self.keyArray.append(actualPost)
}
})
}
#IBAction override func dismissViewController(_ viewController: NSViewController) {
dismiss(self)
}
#IBAction func close(sender: AnyObject) {
self.view.window?.close()
}
#IBAction func onSignup(_ sender: Any) {
// self.performSegue(withIdentifier: NSStoryboardSegue.Identifier(rawValue: "gotosignup"), sender: sender)
// self.view.window?.close()
}
func dialogOK(question: String, text: String) -> Void {
let alert: NSAlert = NSAlert()
alert.messageText = question
alert.informativeText = text
alert.alertStyle = NSAlert.Style.warning
alert.addButton(withTitle: "OK")
alert.runModal()
}
#IBAction func onLogin(_ sender: Any) {
//self.btnLogin.isEnabled = false
var isKey = false
if (!self.textUsername.stringValue.isEmpty) {
for key in keyArray{
if(Int64(self.textUsername.stringValue)! == key)
{
UserDefaults.standard.set(true, forKey:"isRegistered")
self.performSegue(withIdentifier: NSStoryboardSegue.Identifier(rawValue: "loginsegue"), sender: nil)
self.view.window?.close()
isKey = true
}
}
if (!isKey){
self.dialogOK(question: "Error", text: "Invalid Key")
}
} else {
self.dialogOK(question: "Error", text: "Please Input Key")
}
}
}
You can't sort your database like that and expect a working code, even if there's any. It will make a messy code:
You need to:
Sort your database like [1220:0]. the key first. 0 & 1 as an indicator if it's used or not.
Once the user taps onLogin() you need to set the used key value to 1
Setup Cloud Functions to check if the used key is equal to 1, if yes. then remove the key.
Do the rest of the work.

I am trying to stream a music from remote url. I am trying to run this in iOS 11 but it not play the music.

I installed FacebookSDK using Cocoapods, according to Terminal, I have installed FacebookSDK 4.8.0 (CoreKit, ShareKit and LoginKit), I imported the .h files in my BH-File.h, and already initialized everything in my AppDelegate.
For some reason, when trying to log in using a custom button, when I initialize FBLoginManager, I get an error Use of undeclared type "FBLoginManager".
this is my code
if (FBSDKAccessToken.currentAccessToken() == nil)
{
let fbLoginManager : FBSDKLoginManager =
fbLoginManager.logInWithReadPermissions(["public_profile", "email"], fromViewController: self, handler: { (loginResult, error) -> Void in
if error == nil {
print (FBSDKAccessToken.currentAccessToken().tokenString)
}
else {
print ("ERROR*****: \(error)")
}
})
}
What fixed to me was adding import FBSDKCoreKit and FBSDKLoginKit to my class, for some reason is not enough adding it in the BH-file.h
Try something like this, I just checked the code and it works (it's not exactly what you're looking for but I'm sure you can modify it as needed)
import UIKit
import FBSDKCoreKit
import FBSDKLoginKit
class ProfileViewController: UIViewController,FBSDKLoginButtonDelegate {
// #IBOutlet weak var nameLabel: UILabel!
#IBOutlet weak var nameLabel: UILabel!
#IBOutlet weak var imageView: UIImageView!
#IBOutlet weak var nextButton: UIButton!

override func viewDidLoad() {

self.fbLoginButton.delegate = self
self.fbLoginButton.readPermissions = ["public_profile"]
self.fbLoginButton.publishPermissions = ["publish_actions"]
NSNotificationCenter.defaultCenter().addObserver(
self,
selector: "fbProfileChanged:",
name: FBSDKProfileDidChangeNotification,
object: nil)
FBSDKProfile.enableUpdatesOnAccessTokenChange(true)
// If we have a current Facebook access token, force the profile change handler
if ((FBSDKAccessToken.currentAccessToken()) != nil)
{
self.fbProfileChanged(self)
} }

if (error != nil)
{
print( "\(error.localizedDescription)" )
}
else if (result.isCancelled)
{
// Logged out?
print( "Login Cancelled")
}
else
{
// Logged in?
print( "Logged in, segue now")
self.performSegueWithIdentifier("showHome", sender: self)
}
}
func loginButtonDidLogOut(loginButton: FBSDKLoginButton!) {
}
//see bitfountain

let fbProfile = FBSDKProfile.currentProfile()
if (fbProfile != nil)
{
// Fetch & format the profile picture
let strProfilePicURL = fbProfile.imagePathForPictureMode(FBSDKProfilePictureMode.Square, size: imageView.frame.size)
let url = NSURL(string: strProfilePicURL, relativeToURL: NSURL(string: "http://graph.facebook.com/"))
let imageData = NSData(contentsOfURL: url!)
let image = UIImage(data: imageData!)
self.nameLabel.text = fbProfile.name
