Using GCM for push notification in iOS. Everything is set up nicely. I'm getting registrationToken value & also subscribeToTopic successfully. Connected to GCM. didRegisterForRemoteNotificationsWithDeviceToken method also called. But not getting push notification. didReceiveRemoteNotification method never called. On my android app I'm getting the push notification without any problem. But in iOS notification never received. Here is the source code:
class AppDelegate: UIResponder, UIApplicationDelegate, GGLInstanceIDDelegate, GCMReceiverDelegate{
var gcmSenderID: String?
var registrationToken: String?
let registrationKey = "onRegistrationCompleted"
let messageKey = "onMessageReceived"
var registrationOptions = [String: AnyObject]()
var connectedToGCM = false
let subscriptionTopic = "/topics/global"
var subscribedToTopic = false
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
var configureError:NSError?
GGLContext.sharedInstance().configureWithError(&configureError)
gcmSenderID = GGLContext.sharedInstance().configuration.gcmSenderID
if application.respondsToSelector("registerUserNotificationSettings:") {
let types:UIUserNotificationType = (.Alert | .Badge | .Sound)
let settings:UIUserNotificationSettings = UIUserNotificationSettings(forTypes: types, categories: nil)
application.registerUserNotificationSettings(settings)
application.registerForRemoteNotifications()
} else {
// Register for Push Notifications before iOS 8
application.registerForRemoteNotificationTypes(.Alert | .Badge | .Sound)
}
let gcmConfig = GCMConfig.defaultConfig()
gcmConfig.receiverDelegate = self
GCMService.sharedInstance().startWithConfig(gcmConfig)
return true
}
func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject]) {
print("remote notification")
GCMService.sharedInstance().appDidReceiveMessage(userInfo);
}
func application( application: UIApplication,
didReceiveRemoteNotification userInfo: [NSObject : AnyObject],
fetchCompletionHandler handler: (UIBackgroundFetchResult) -> Void) {
GCMService.sharedInstance().appDidReceiveMessage(userInfo);
NSNotificationCenter.defaultCenter().postNotificationName(messageKey, object: nil,
userInfo: userInfo)
handler(UIBackgroundFetchResult.NoData);
}
func application( application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken
deviceToken: NSData ) {
let instanceIDConfig = GGLInstanceIDConfig.defaultConfig()
instanceIDConfig.delegate = self
GGLInstanceID.sharedInstance().startWithConfig(instanceIDConfig)
registrationOptions = [kGGLInstanceIDRegisterAPNSOption:deviceToken,
kGGLInstanceIDAPNSServerTypeSandboxOption:true]
GGLInstanceID.sharedInstance().tokenWithAuthorizedEntity(gcmSenderID,
scope: kGGLInstanceIDScopeGCM, options: registrationOptions, handler: registrationHandler)
// [END get_gcm_reg_token]
}
func onTokenRefresh() {
// A rotation of the registration tokens is happening, so the app needs to request a new token.
print("The GCM registration token needs to be changed.")
GGLInstanceID.sharedInstance().tokenWithAuthorizedEntity(gcmSenderID,
scope: kGGLInstanceIDScopeGCM, options: registrationOptions, handler: registrationHandler)
}
func registrationHandler(registrationToken: String!, error: NSError!) {
if (registrationToken != nil) {
self.registrationToken = registrationToken
print("Registration Token: \(registrationToken)")
self.subscribeToTopic()
let userInfo = ["registrationToken": registrationToken]
NSNotificationCenter.defaultCenter().postNotificationName(
self.registrationKey, object: nil, userInfo: userInfo)
} else {
print("Registration to GCM failed with error: \(error.localizedDescription)")
let userInfo = ["error": error.localizedDescription]
NSNotificationCenter.defaultCenter().postNotificationName(
self.registrationKey, object: nil, userInfo: userInfo)
}
}
func subscribeToTopic() {
// topic
if(registrationToken != nil && connectedToGCM) {
GCMPubSub.sharedInstance().subscribeWithToken(self.registrationToken, topic: subscriptionTopic,
options: nil, handler: {(NSError error) -> Void in
if (error != nil) {
// Treat the "already subscribed" error more gently
if error.code == 3001 {
print("Already subscribed to \(self.subscriptionTopic)")
} else {
print("Subscription failed: \(error.localizedDescription)");
}
} else {
self.subscribedToTopic = true;
NSLog("Subscribed to \(self.subscriptionTopic)");
}
})
}
}
func applicationDidBecomeActive(application: UIApplication) {
print("applicationDidBecomeActive")
self.globalPrice = CartLocalData.getTotalPrice()
GCMService.sharedInstance().connectWithHandler({
(NSError error) -> Void in
if error != nil {
print("Could not connect to GCM: \(error.localizedDescription)")
} else {
self.connectedToGCM = true
self.subscribeToTopic()
print("Connected to GCM")
// ...
}
})
}
}
What am I doing wrong. Can anyone suggest??
