ios10, Swift 3 and Firebase Push Notifications (FCM)
Inside method didRegisterForRemoteNotificationsWithDeviceToken, add the following code:
func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {
let tokenChars = UnsafePointer<CChar>(deviceToken.bytes)
var tokenString = ""
for i in 0..<deviceToken.length {
tokenString += String(format: "%02.2hhx", arguments: [tokenChars[i]])
}
FIRInstanceID.instanceID().setAPNSToken(deviceToken, type: FIRInstanceIDAPNSTokenType.Unknown)
print("tokenString: \(tokenString)")
}
And do not forget to enable Push Notifications inside Capabilities.
Push Notifications not being received on iOS 10, but working on iOS 9 and before
Ok I have figured it out. I now have my original Push Notifications that was working on iOS 9 working on iOS 10 with Xcode 8 and Swift 2.3.
I implemented this by making the following changes to my AppDelegate:
1) On my project settings, under the Capabilities Tab, I scroll down to "Push Notifications" and turn it to "ON". This automatically generates an entitlements file that contains the key "APS Environment" and with value "development".
2) In AppDelegate.swift I make several code changes. I start by importing the UserNotifications framework:
import UserNotifications
Then I have AppDelegate implement the UNUserNotificationCenterDelegate protocol:
class AppDelegate: /*Some other protocols I am extending...*/, UNUserNotificationCenterDelegate {
Then I add the following method:
func registerForPushNotifications(application: UIApplication) {
if #available(iOS 10.0, *){
UNUserNotificationCenter.currentNotificationCenter().delegate = self
UNUserNotificationCenter.currentNotificationCenter().requestAuthorizationWithOptions([.Badge, .Sound, .Alert], completionHandler: {(granted, error) in
if (granted)
{
UIApplication.sharedApplication().registerForRemoteNotifications()
}
else{
//Do stuff if unsuccessful...
}
})
}
else{ //If user is not on iOS 10 use the old methods we've been using
let notificationSettings = UIUserNotificationSettings(
forTypes: [.Badge, .Sound, .Alert], categories: nil)
application.registerUserNotificationSettings(notificationSettings)
}
}
Then I call this newly created function inside didFinishLaunchingWithOptions:
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
...
registerForPushNotifications(application)
...
}
I leave my didRegisterForRemoteNotificationsWithDeviceToken method unchanged:
func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {
//Implement this. Do something with the token I receive. Send it to my push notification server to register the device or something else I'd like to do with the token.
}
Now I implement two new methods for iOS 10 to handle the receiving of Push Notifications:
@available(iOS 10.0, *)
func userNotificationCenter(center: UNUserNotificationCenter, willPresentNotification notification: UNNotification, withCompletionHandler completionHandler: (UNNotificationPresentationOptions) -> Void) {
//Handle the notification
}
@available(iOS 10.0, *)
func userNotificationCenter(center: UNUserNotificationCenter, didReceiveNotificationResponse response: UNNotificationResponse, withCompletionHandler completionHandler: () -> Void) {
//Handle the notification
}
I did not remove any of the methods I have previously implemented for Push Notifications in iOS 9.
APNS Firebase Notification failed to fetch token
1.Set Notification Observer in didFinishLaunchingWithOptions Method
2.And Set tokenRefreshNotification method then u get Token in this method.
See below Code
import Firebase
import FirebaseMessaging
override func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
FIRApp.configure()
NotificationCenter.default.addObserver(self,
selector: #selector(self.tokenRefreshNotification(notification:)),
name: NSNotification.Name.firInstanceIDTokenRefresh,
object: nil)
}
// NOTE: Need to use this when swizzling is disabled
public func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {
FIRInstanceID.instanceID().setAPNSToken(deviceToken, type: FIRInstanceIDAPNSTokenType.Sandbox)
}
func tokenRefreshNotification(notification: NSNotification) {
// NOTE: It can be nil here
let refreshedToken = FIRInstanceID.instanceID().token()
print("InstanceID token: \(refreshedToken)")
connectToFcm()
}
func connectToFcm() {
FIRMessaging.messaging().connectWithCompletion { (error) in
if (error != nil) {
print("Unable to connect with FCM. \(error)")
} else {
print("Connected to FCM.")
}
}
}
public func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject]) {
print(userInfo)
}
Get push notification while App in foreground iOS
If the application is running in the foreground, iOS won't show a notification banner/alert. That's by design. But we can achieve it by using UILocalNotification
as follows
Check whether application is in active state on receiving a remote
notification. If in active state fire a UILocalNotification.if (application.applicationState == UIApplicationStateActive ) {
UILocalNotification *localNotification = [[UILocalNotification alloc] init];
localNotification.userInfo = userInfo;
localNotification.soundName = UILocalNotificationDefaultSoundName;
localNotification.alertBody = message;
localNotification.fireDate = [NSDate date];
[[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
}
SWIFT:
if application.applicationState == .active {
var localNotification = UILocalNotification()
localNotification.userInfo = userInfo
localNotification.soundName = UILocalNotificationDefaultSoundName
localNotification.alertBody = message
localNotification.fireDate = Date()
UIApplication.shared.scheduleLocalNotification(localNotification)
}
Cloud messaging handing terminate app
Here is the solution,
First Upload the necessary certificates in Firebase Console Then in your app enable Push Notifications and Background Modes -> Remote Notifications
After that in App Delegate use the code below(I specify the tricky line) :
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
registerForPushNotifications(application)
// Override point for customization after application launch.
// Use Firebase library to configure APIs
FIRApp.configure()
return true
}
func registerForPushNotifications(application: UIApplication) {
let notificationSettings = UIUserNotificationSettings(
forTypes: [.Badge, .Sound, .Alert], categories: nil)
application.registerUserNotificationSettings(notificationSettings)
}
func application(application: UIApplication, didRegisterUserNotificationSettings notificationSettings: UIUserNotificationSettings) {
if notificationSettings.types != .None {
application.registerForRemoteNotifications()
}
}
func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {
let tokenChars = UnsafePointer<CChar>(deviceToken.bytes)
var tokenString = ""
for i in 0..<deviceToken.length {
tokenString += String(format: "%02.2hhx", arguments: [tokenChars[i]])
}
//Tricky line
FIRInstanceID.instanceID().setAPNSToken(deviceToken, type: FIRInstanceIDAPNSTokenType.Unknown)
print("Device Token:", tokenString)
}
UNUserNotificationCenter did receive response with completion handler is never called iOS10, swift 2.3
Request identifier is not the notification category.
Just add this line:
content.categoryIdentifier = identifier
Update:
Just made a simple app. Everything seems to working fine:
class AppDelegate: UIResponder, UIApplicationDelegate, UNUserNotificationCenterDelegate {
var window: UIWindow?
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
UNUserNotificationCenter.current().delegate = self
UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .badge, .sound]) { (granted, error) in
if granted {
self.registerCategory()
self.scheduleNotification(event: "test", interval: 3)
self.scheduleNotification(event: "test2", interval: 5)
}
}
return true
}
func registerCategory() -> Void{
let callNow = UNNotificationAction(identifier: "call", title: "Call now", options: [])
let clear = UNNotificationAction(identifier: "clear", title: "Clear", options: [])
let category : UNNotificationCategory = UNNotificationCategory.init(identifier: "CALLINNOTIFICATION", actions: [callNow, clear], intentIdentifiers: [], options: [])
let center = UNUserNotificationCenter.current()
center.setNotificationCategories([category])
}
func scheduleNotification (event : String, interval: TimeInterval) {
let content = UNMutableNotificationContent()
content.title = event
content.body = "body"
content.categoryIdentifier = "CALLINNOTIFICATION"
let trigger = UNTimeIntervalNotificationTrigger.init(timeInterval: interval, repeats: false)
let identifier = "id_"+event
let request = UNNotificationRequest.init(identifier: identifier, content: content, trigger: trigger)
let center = UNUserNotificationCenter.current()
center.add(request, withCompletionHandler: { (error) in
})
}
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
print("didReceive")
completionHandler()
}
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
print("willPresent")
completionHandler([.badge, .alert, .sound])
}
}
Update 2: Rewritten in Swift 2.3
class AppDelegate: UIResponder, UIApplicationDelegate, UNUserNotificationCenterDelegate {
var window: UIWindow?
func applicationDidFinishLaunching(application: UIApplication) {
UNUserNotificationCenter.currentNotificationCenter().delegate = self
UNUserNotificationCenter.currentNotificationCenter().requestAuthorizationWithOptions([.Badge, .Sound, .Alert]) { (granted, error) in
if granted {
self.registerCategory()
self.scheduleNotification("test", interval: 3)
self.scheduleNotification("test2", interval: 5)
}
}
}
func registerCategory() -> Void{
let callNow = UNNotificationAction(identifier: "call", title: "Call now", options: [])
let clear = UNNotificationAction(identifier: "clear", title: "Clear", options: [])
let category : UNNotificationCategory = UNNotificationCategory.init(identifier: "CALLINNOTIFICATION", actions: [callNow, clear], intentIdentifiers: [], options: [])
let center = UNUserNotificationCenter.currentNotificationCenter()
center.setNotificationCategories([category])
}
func scheduleNotification(event : String, interval: NSTimeInterval) {
let content = UNMutableNotificationContent()
content.title = event
content.body = "body"
content.categoryIdentifier = "CALLINNOTIFICATION"
let trigger = UNTimeIntervalNotificationTrigger.init(timeInterval: interval, repeats: false)
let identifier = "id_"+event
let request = UNNotificationRequest.init(identifier: identifier, content: content, trigger: trigger)
let center = UNUserNotificationCenter.currentNotificationCenter()
center.addNotificationRequest(request) { (error) in
}
}
func userNotificationCenter(center: UNUserNotificationCenter, willPresentNotification notification: UNNotification, withCompletionHandler completionHandler: (UNNotificationPresentationOptions) -> Void) {
print("willPresent")
completionHandler([.Badge, .Alert, .Sound])
}
func userNotificationCenter(center: UNUserNotificationCenter, didReceiveNotificationResponse response: UNNotificationResponse, withCompletionHandler completionHandler: () -> Void) {
print("didReceive")
completionHandler()
}
}
