iOS FCM Messaging in Swift Initialize FCM in Swift
Example
follow below step to add FCM in your swift Project
1- If you don't have an Xcode project yet, create one now. Create a Podfile if you don't have one:
$ cd your-project directory
$ pod init
2- Add the pods that you want to install. You can include a Pod in your Podfile like this:
pod 'Firebase/Core'
pod 'Firebase/Messaging'
3- Install the pods and open the .xcworkspace file to see the project in Xcode.
$ pod install
$ open your-project.xcworkspace
4- Download a GoogleService-Info.plist file from plist and include it in your app.
5- Upload APNs certificate to Firebase. APN Cert
6- add "import Firebase" in your appDelegate file of project
7- add this "FIRApp.configure()" in your "application:didFinishLaunchingWithOptions"
8- register for remote notification
if #available(iOS 10.0, *) {
let authOptions : UNAuthorizationOptions = [.Alert, .Badge, .Sound]
UNUserNotificationCenter.currentNotificationCenter().requestAuthorizationWithOptions(
authOptions,
completionHandler: {_,_ in })
// For iOS 10 display notification (sent via APNS)
UNUserNotificationCenter.currentNotificationCenter().delegate = self
// For iOS 10 data message (sent via FCM)
FIRMessaging.messaging().remoteMessageDelegate = self
} else {
let settings: UIUserNotificationSettings =
UIUserNotificationSettings(forTypes: [.Alert, .Badge, .Sound], categories: nil)
application.registerUserNotificationSettings(settings)
}
application.registerForRemoteNotifications()
9- to get register token use
let token = FIRInstanceID.instanceID().token()!
10- and if u want monitor for token change use below code in appDelegate file
func tokenRefreshNotification(notification: NSNotification) {
if let refreshedToken = FIRInstanceID.instanceID().token() {
print("InstanceID token: \(refreshedToken)")
}
// Connect to FCM since connection may have failed when attempted before having a token.
connectToFcm()
}
11- to recieve message from fcm add below code in appDelegate
func connectToFcm() {
FIRMessaging.messaging().connectWithCompletion { (error) in
if (error != nil) {
print("Unable to connect with FCM. \(error)")
} else {
print("Connected to FCM.")
}
}
}
12- and for disconnect use
func applicationDidEnterBackground(application: UIApplication) {
FIRMessaging.messaging().disconnect()
print("Disconnected from FCM.")
}
in your appDelegate.
the initialization complete and client ready to recieve message from fcm panel or send by token from third party server
