When I try to connect to Facebook in my iOS application, the app redirects me to the Facebook app and then there is a loop between the two apps, meaning that the user is being sent back and forth between the two apps without being able to complete the login process. I suspect that there is something missing in my code to properly handle the redirect URLs for the PianoID SDK and I would like to know what needs to be done to fix this issue.
this is my appDelegate class :
#objc class AppDelegate: FlutterAppDelegate, PianoIDDelegate {
private var flutterResult: FlutterResult? = nil
#Published private(set) var initialized = false
#Published private(set) var token: PianoIDToken?
var cookiessseion = ""
var startdate = ""
var enddate = ""
var pianoToken=""
func pianoID(_ pianoID: PianoOAuth.PianoID, didSignInForToken token: PianoOAuth.PianoIDToken!, withError error: Error!) {}
func pianoID(_ pianoID: PianoOAuth.PianoID, didSignOutWithError error: Error!) {}
func pianoIDSignInDidCancel(_ pianoID: PianoOAuth.PianoID) {}
override func application(_ application: UIApplication,
didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
PianoID.shared.endpointUrl = Settings.endpoint.api
PianoID.shared.aid = Settings.aid
PianoID.shared.isSandbox = true
PianoID.shared.signUpEnabled = true
PianoID.shared.googleClientId = Settings.clientId
PianoID.shared.delegate = self
PianoOAuth.PianoIDApplicationDelegate.shared.application(application, didFinishLaunchingWithOptions: launchOptions)
GeneratedPluginRegistrant.register(with: self)
let name = Bundle.main.infoDictionary?["CFBundleName"]
let version = Bundle.main.infoDictionary?["CFBundleShortVersionString"]
GEMConfig.sharedInstance().setAppInfo(name as? String, version: version as? String)
//FirebaseApp.configure()
guard let controller = window?.rootViewController as? FlutterViewController else {
fatalError("rootViewController is not type FlutterViewController")
}
let Channel = FlutterMethodChannel(name: "flutter.native/helper", binaryMessenger: controller.binaryMessenger)
Channel.setMethodCallHandler({
[weak self] (call: FlutterMethodCall, result: #escaping FlutterResult) -> Void in
if(call.method == "testpiano"){
self?.initPianoID()
self?.flutterResult = result
} else {
result(FlutterMethodNotImplemented)
}
})
return super.application(application, didFinishLaunchingWithOptions: launchOptions)
}
/// Sign In callback
func signIn(result: PianoIDSignInResult!, withError error: Error!) {
if let r = result {
token = r.token
do {
let PianoIDTokenString = try JSONParserSwift.getJSON(object: token)
self.flutterResult?(PianoIDTokenString)
} catch {
print("Unexpected data error: \(error)")
}
} else {
}
}
/// Sign Out callback
func signOut(withError error: Error!) {
token = nil
}
/// Cancel callback
func cancel() {
}
private func initPianoID() {
PianoID.shared.signIn()
}
func openSettings(alert: UIAlertAction!) {
if let url = URL.init(string: UIApplication.openSettingsURLString) {
UIApplication.shared.open(url, options: [:], completionHandler: nil)
}
}
override public func applicationDidBecomeActive(_ application: UIApplication) {
debugPrint("applicationDidBecomeActive")
if #available(iOS 14, *) {
DispatchQueue.main.asyncAfter(deadline: .now() + 2) {
ATTrackingManager.requestTrackingAuthorization { status in
}
}
}
}
}
extension Date {
func currentTimeMillis() -> Int64 {
return Int64(self.timeIntervalSince1970)
}
}

How to solve this issue in swift. I have to check the network connection. If the internet is not connected to the device I have to show this offlineViewController. if it is connected then it shows Normal screen.
I am using this class to control network change -> Reachability.swift :
import Foundation
import SystemConfiguration
class Reachability {
var hostname: String?
var isRunning = false
var isReachableOnWWAN: Bool
var reachability: SCNetworkReachability?
var reachabilityFlags = SCNetworkReachabilityFlags()
let reachabilitySerialQueue = DispatchQueue(label: "ReachabilityQueue")
init?(hostname: String) throws {
guard let reachability = SCNetworkReachabilityCreateWithName(nil, hostname) else {
throw Network.Error.failedToCreateWith(hostname)
}
self.reachability = reachability
self.hostname = hostname
isReachableOnWWAN = true
}
init?() throws {
var zeroAddress = sockaddr_in()
zeroAddress.sin_len = UInt8(MemoryLayout<sockaddr_in>.size)
zeroAddress.sin_family = sa_family_t(AF_INET)
guard let reachability = withUnsafePointer(to: &zeroAddress, {
$0.withMemoryRebound(to: sockaddr.self, capacity: 1) {
SCNetworkReachabilityCreateWithAddress(nil, $0)
}}) else {
throw Network.Error.failedToInitializeWith(zeroAddress)
}
self.reachability = reachability
isReachableOnWWAN = true
}
var status: Network.Status {
return !isConnectedToNetwork ? .unreachable :
isReachableViaWiFi ? .wifi :
isRunningOnDevice ? .wwan : .unreachable
}
var isRunningOnDevice: Bool = {
#if (arch(i386) || arch(x86_64)) && os(iOS)
return false
#else
return true
#endif
}()
deinit { stop() }
}
extension Reachability {
func start() throws {
guard let reachability = reachability, !isRunning else { return }
var context = SCNetworkReachabilityContext(version: 0, info: nil, retain: nil, release: nil, copyDescription: nil)
context.info = Unmanaged<Reachability>.passUnretained(self).toOpaque()
guard SCNetworkReachabilitySetCallback(reachability, callout, &context) else { stop()
throw Network.Error.failedToSetCallout
}
guard SCNetworkReachabilitySetDispatchQueue(reachability, reachabilitySerialQueue) else { stop()
throw Network.Error.failedToSetDispatchQueue
}
reachabilitySerialQueue.async { self.flagsChanged() }
isRunning = true
}
func stop() {
defer { isRunning = false }
guard let reachability = reachability else { return }
SCNetworkReachabilitySetCallback(reachability, nil, nil)
SCNetworkReachabilitySetDispatchQueue(reachability, nil)
self.reachability = nil
}
var isConnectedToNetwork: Bool {
return isReachable &&
!isConnectionRequiredAndTransientConnection &&
!(isRunningOnDevice && isWWAN && !isReachableOnWWAN)
}
var isReachableViaWiFi: Bool {
return isReachable && isRunningOnDevice && !isWWAN
}
/// Flags that indicate the reachability of a network node name or address, including whether a connection is required, and whether some user intervention might be required when establishing a connection.
var flags: SCNetworkReachabilityFlags? {
guard let reachability = reachability else { return nil }
var flags = SCNetworkReachabilityFlags()
return withUnsafeMutablePointer(to: &flags) {
SCNetworkReachabilityGetFlags(reachability, UnsafeMutablePointer($0))
} ? flags : nil
}
/// compares the current flags with the previous flags and if changed posts a flagsChanged notification
func flagsChanged() {
guard let flags = flags, flags != reachabilityFlags else { return }
reachabilityFlags = flags
NotificationCenter.default.post(name: .flagsChanged, object: self)
}
/// The specified node name or address can be reached via a transient connection, such as PPP.
var transientConnection: Bool { return flags?.contains(.transientConnection) == true }
/// The specified node name or address can be reached using the current network configuration.
var isReachable: Bool { return flags?.contains(.reachable) == true }
/// The specified node name or address can be reached using the current network configuration, but a connection must first be established. If this flag is set, the kSCNetworkReachabilityFlagsConnectionOnTraffic flag, kSCNetworkReachabilityFlagsConnectionOnDemand flag, or kSCNetworkReachabilityFlagsIsWWAN flag is also typically set to indicate the type of connection required. If the user must manually make the connection, the kSCNetworkReachabilityFlagsInterventionRequired flag is also set.
var connectionRequired: Bool { return flags?.contains(.connectionRequired) == true }
/// The specified node name or address can be reached using the current network configuration, but a connection must first be established. Any traffic directed to the specified name or address will initiate the connection.
var connectionOnTraffic: Bool { return flags?.contains(.connectionOnTraffic) == true }
/// The specified node name or address can be reached using the current network configuration, but a connection must first be established.
var interventionRequired: Bool { return flags?.contains(.interventionRequired) == true }
/// The specified node name or address can be reached using the current network configuration, but a connection must first be established. The connection will be established "On Demand" by the CFSocketStream programming interface (see CFStream Socket Additions for information on this). Other functions will not establish the connection.
var connectionOnDemand: Bool { return flags?.contains(.connectionOnDemand) == true }
/// The specified node name or address is one that is associated with a network interface on the current system.
var isLocalAddress: Bool { return flags?.contains(.isLocalAddress) == true }
/// Network traffic to the specified node name or address will not go through a gateway, but is routed directly to one of the interfaces in the system.
var isDirect: Bool { return flags?.contains(.isDirect) == true }
/// The specified node name or address can be reached via a cellular connection, such as EDGE or GPRS.
var isWWAN: Bool { return flags?.contains(.isWWAN) == true }
/// The specified node name or address can be reached using the current network configuration, but a connection must first be established. If this flag is set
/// The specified node name or address can be reached via a transient connection, such as PPP.
var isConnectionRequiredAndTransientConnection: Bool {
return (flags?.intersection([.connectionRequired, .transientConnection]) == [.connectionRequired, .transientConnection]) == true
}
}
func callout(reachability: SCNetworkReachability, flags: SCNetworkReachabilityFlags, info: UnsafeMutableRawPointer?) {
guard let info = info else { return }
DispatchQueue.main.async {
Unmanaged<Reachability>.fromOpaque(info).takeUnretainedValue().flagsChanged()
}
}
extension Notification.Name {
static let flagsChanged = Notification.Name("FlagsChanged")
}
struct Network {
static var reachability: Reachability?
enum Status: String, CustomStringConvertible {
case unreachable, wifi, wwan
var description: String { return rawValue }
}
enum Error: Swift.Error {
case failedToSetCallout
case failedToSetDispatchQueue
case failedToCreateWith(String)
case failedToInitializeWith(sockaddr_in)
}
}
And I add this code to AppDelegate.swift :
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
do {
Network.reachability = try Reachability(hostname: "www.google.com")
do {
try Network.reachability?.start()
} catch let error as Network.Error {
print(error)
} catch {
print(error)
}
} catch {
print(error)
}
return true
}
And I add this code to viewDidLoad() in the class I want to control the network:
NotificationCenter.default.addObserver(self, selector: #selector(statusManager), name: .flagsChanged, object: Network.reachability)
You can make checks in this function when the network changes.
func statusManager(_ notification: NSNotification) {
guard let status = Network.reachability?.status else { return }
if status == .wifi || status == .wwan {
offlineViewController.dismiss(animated: true, completion: nil)
}
print("Status:", status)
print("HostName:", Network.reachability?.hostname ?? "nil")
print("Reachable:", Network.reachability?.isReachable ?? "nil")
print("Wifi:", Network.reachability?.isReachableViaWiFi ?? "nil")
}
import Alamofire
struct Connectivity {
static let sharedInstance = NetworkReachabilityManager()!
static var isConnectedToInternet:Bool {
return self.sharedInstance.isReachable
}
}
Usage :
if Connectivity.isConnectedToInternet {
return true
} else {
self.setErrorMessage(message: "No internet connection", view: view)
return false
}
NetworkManager Class
class NetworkManager {
//shared instance
static let shared = NetworkManager()
let reachabilityManager = Alamofire.NetworkReachabilityManager(host: "www.google.com")
let offlineViewController = OfflineViewController()
let currentViewController: UIViewController?
func startNetworkReachabilityObserver() {
reachabilityManager?.listener = { status in
switch status {
case .notReachable:
offlineViewController.dismiss(animated: false, completion: nil)
currentViewController.present(offlineViewController, animated: true, completion: nil)
print("The network is not reachable")
case .unknown :
print("It is unknown whether the network is reachable")
case .reachable(.ethernetOrWiFi):
offlineViewController.dismiss(animated: true, completion: nil)
print("The network is reachable over the WiFi connection")
case .reachable(.wwan):
offlineViewController.dismiss(animated: true, completion: nil)
print("The network is reachable over the WWAN connection")
}
}
// start listening
reachabilityManager?.startListening()
}
}
Start Network Reachability Observer
#UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// add network reachability observer on app start
NetworkManager.shared.startNetworkReachabilityObserver()
return true
}
}
On each ViewController need to detect network
override func viewDidLoad() {
super.viewDidLoad()
NetworkManager.shared.currentViewController = self
}
Here I use Alamofire version 5.2
NetworkReachabilityManager handler
import Alamofire
class NetworkReachability{
let sceneDelegate: SceneDelegate = {
let scene = UIApplication.shared.connectedScenes.first
let sd = scene?.delegate as? SceneDelegate
return sd ?? SceneDelegate()
}()
var manager:NetworkReachabilityManager?
init(
manager:NetworkReachabilityManager? = NetworkReachabilityManager()
) {
self.manager = manager
self.managerHandler()
}
private func managerHandler(){
self.manager?.startListening(onUpdatePerforming: { (status) in
switch status{
case .unknown:
self.sceneDelegate.showOfflineViewController()
case .notReachable:
print("Not Reachable")
self.sceneDelegate.showOfflineViewController()
case .reachable(.cellular),.reachable(.ethernetOrWiFi):
print("Reachable")
self.sceneDelegate.hideOfflineViewController()
}
})
}
}
SceneDelegate
import UIKit
class SceneDelegate: UIResponder, UIWindowSceneDelegate {
var window: UIWindow?
var offlineWindow:UIWindow?
private var networkReachability:NetworkReachability?
func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
guard let _ = (scene as? UIWindowScene) else { return }
self.networkReachability = NetworkReachability()
}
}
extension SceneDelegate{
func showOfflineViewController(){
guard let offlineWindow = window?.windowScene else { return }
let offlineViewController = OfflineViewController
self.offlineWindow = UIWindow(windowScene: offlineWindow)
self.offlineWindow?.rootViewController = offlineViewController
self.offlineWindow?.makeKeyAndVisible()
}
func hideOfflineViewController(){
UIView.animate(withDuration: 0.3) {
self.offlineWindow?.alpha = 0
} completion: { (_) in
self.offlineWindow?.isHidden = true
self.offlineWindow = nil
}
}
}
While trying to bind some protocols to various classes I have encountered a strange behaviour of getting nil in the protocols.
This is the dependency injector class:
class DependencyInjector: NSObject {
let container: Container
override init() {
container = Container()
super.init()
register()
}
}
extension DependencyInjector {
func register() {
container.register(NetworkProtocols.self) { _ in ApiManager() }.inObjectScope(.container)
container.register(ConnectivityManager.self) { r in
let controller = ConnectivityManager()
controller.network = r.resolve(NetworkProtocols.self)
return controller
}
container.storyboardInitCompleted(ChooseCameraViewController.self) {r,c in
c.network = r.resolve(NetworkProtocols.self)
}
container.storyboardInitCompleted(InstallationViewController.self) {r,c in
c.network = r.resolve(NetworkProtocols.self)
}
container.storyboardInitCompleted(CameraSetupViewController.self) {r,c in
c.network = r.resolve(NetworkProtocols.self)
}
container.storyboardInitCompleted(LoginViewController.self) { r,c in
c.network = r.resolve(NetworkProtocols.self)
}
}
}
This is the AppDelegate:
var dependencyInjector: DependencyInjector!
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
dependencyInjector = DependencyInjector()
let window = UIWindow(frame: UIScreen.main.bounds)
self.window = window
let bundle = Bundle(for: ViewController.self)
let storyboard = SwinjectStoryboard.create(name: "Main", bundle: bundle, container: dependencyInjector.container)
window.rootViewController = storyboard.instantiateInitialViewController()
return true
}
In the class below I get nil in the protocol property:
class ConnectivityManager: NSObject {
var network: NetworkProtocols!
func connectHotSpot() {
self.network.whoAmI(success: {
print("api succses")
}, failure: { (error) in
print(error.localizedDescription)
})
}
}
The network var is always nil while in the other classes that use storyboardInitCompleted the network var works.
What am I doing wrong?
As #JakubVano said I had to obtain an instance of ConnectivityManager:
container.register(ConnectivityManager.self) { r in
let controller = ConnectivityManager()
controller.network = r.resolve(NetworkProtocols.self)
return controller
}
container.storyboardInitCompleted(ChooseCameraViewController.self) {r,c in
c.connectivityManager = r.resolve(ConnectivityManager.self)!
}
I want to implement Stripe Payment gateway. And need to generate token and pass it to backend.
private func getToken(){
let cardParams = STPCardParams()
cardParams.number = paymentCardTextField?.cardNumber
cardParams.expMonth = (paymentCardTextField?.expirationMonth)!
cardParams.expYear = (paymentCardTextField?.expirationYear)!
cardParams.cvc = paymentCardTextField?.cvc
STPAPIClient.shared().createToken(withCard: cardParams) { (token: STPToken?, error: Error?) in
guard let token = token, error == nil else {
// Present error to user...
return
}
self.dictPayData["stripe_token"] = token.tokenId
print(self.dictPayData)
}
}
Make sure you need to add your Stripe publishableKey (live/test)
in AppDelegate.swift
import Stripe
class AppDelegate: UIResponder, UIApplicationDelegate{
// var navCon: UINavigationController?
var window: UIWindow?
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application la
STPPaymentConfiguration.shared().publishableKey = "pk_test_DSFDSFSDFDFSDFSDFDSDSF"
return true
}
}
in my PaymentView.swift
Note: Use STPPaymentCardTextFieldDelegate for card validation.
class PaymentView: UIViewController,STPPaymentCardTextFieldDelegate {
#IBOutlet weak var paymentCardTextField = STPPaymentCardTextField()
}
private func getToken(){
let cardParams = STPCardParams()
cardParams.number = paymentCardTextField?.cardNumber
cardParams.expMonth = (paymentCardTextField?.expirationMonth)!
cardParams.expYear = (paymentCardTextField?.expirationYear)!
cardParams.cvc = paymentCardTextField?.cvc
STPAPIClient.shared().createToken(withCard: cardParams) { (token: STPToken?, error: Error?) in
guard let token = token, error == nil else {
// Present error to user...
return
}
self.dictPayData["stripe_token"] = token.tokenId
print(self.dictPayData)
}
}
On the networking side, DNS Proxy is one of the biggest features of iOS 11. But they haven't provided much documentation or samples regarding it. There's a talk on it as well where they have just given a description of what is possible with DNS Proxy.
I want to create a working sample of it but didn't get success till now. So I have created a Network Extension with DNS Proxy entitlements and added a DNS Proxy Provider. Here's the code:
class DNSProxyProvider: NEDNSProxyProvider {
let defaults = UserDefaults(suiteName: "group.com.securly.dnsProxy")
override init() {
NSLog("QNEDNSProxy.Provider: init")
super.init()
// +++ might want to set up KVO on `systemDNSSettings`
}
override func startProxy(options:[String: Any]? = nil, completionHandler: #escaping (Error?) -> Void) {
NSLog("QNEDNSProxy.Provider: start")
// self.defaults?.set("DidStart", forKey: "DidStart")
completionHandler(nil)
}
override func stopProxy(with reason: NEProviderStopReason, completionHandler: #escaping () -> Void) {
NSLog("QNEDNSProxy.Provider: stop")
completionHandler()
}
override func handleNewFlow(_ flow: NEAppProxyFlow) -> Bool {
NSLog("QNEDNSProxy.Provider: new flow (denied)")
// self.defaults?.set("DidHandleNewFlow", forKey: "DidHandleNewFlow")
return true
}
}
Then in AppDelegate, I declare a NEDNSProxyManager and use it as:
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
let manager = NEDNSProxyManager.shared()
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
self.enable()
return true
}
private func enable() {
self.update {
self.manager.localizedDescription = "DNSProxySample"
let proto = NEDNSProxyProviderProtocol()
// proto.providerConfiguration = +++
proto.providerBundleIdentifier = "com.securly.dnsProxy"
self.manager.providerProtocol = proto
self.manager.isEnabled = true
}
}
private func disable() {
self.update {
self.manager.isEnabled = false
}
}
private func update(_ body: #escaping () -> Void) {
self.manager.loadFromPreferences { (error) in
guard error == nil else {
NSLog("DNSProxySample.App: load error")
return
}
body()
self.manager.saveToPreferences { (error) in
guard error == nil else {
NSLog("DNSProxySample.App: save error")
return
}
NSLog("DNSProxySample.App: saved")
}
}
}
}
Questions/Issues:
Why isn't startProxy or handleNewFlow called? Is there anything wrong in the setup?
How do I mention custom DNS address?
I managed to trigger startProxy and handleFlow on DNSProxyProvider by system. My configurations are like this:
Entitlements on app target
Entitlements on DNSProxy Extension
Red line is something similar to: group.com.xzy.project_name
Info.plist file on Extension
AppDelegate
import UIKit
import NetworkExtension
#UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
let manager = NEDNSProxyManager.shared()
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
self.enable()
return true
}
private func enable() {
self.update {
self.manager.localizedDescription = "DNS"
let proto = NEDNSProxyProviderProtocol()
proto.providerBundleIdentifier = "EXTENSION_BUNDLE_IDENTIFIER_WHICH_HAS_DNS_PROXY"
self.manager.providerProtocol = proto
self.manager.isEnabled = true
}
}
private func disable() {
self.update {
self.manager.isEnabled = false
}
}
private func update(_ body: #escaping () -> Void) {
self.manager.loadFromPreferences { (error) in
guard error == nil else {
NSLog("DNS Test App: load error")
return
}
body()
self.manager.saveToPreferences { (error) in
guard error == nil else {
NSLog("DNS Test App: save error")
return
}
NSLog("DNS Test App: saved")
}
}
}
}
DO NOT FORGET TO CHANGE BUNDLE IDENTIFIER at here proto.providerBundleIdentifier = "EXTENSION_BUNDLE_IDENTIFIER_WHICH_HAS_DNS_PROXY"

import NetworkExtension
class DNSProxyProvider: NEDNSProxyProvider {
override init() {

let localPort = (udpFlow.localEndpoint as! NWHostEndpoint).port
NSLog("DNSProxyProvider UDP HOST : \(localHost)")
NSLog("DNSProxyProvider UDP PORT : \(localPort)")
}
return true
}
}
As a last step run the app on a real iOS Device.
If you want to display extension logs open Console.app from your Mac.
To debug the extension: Your main app should be selected from run menu. Select Attach to Process by PID or Name... from Xcode's Debug menu and then type your extension's name, press Attach button. After you see the Waiting to attach to EXTENSION_NAME on XYZ's iPhone. Run your app target on a iOS device.
