I have several apps that were written in Swift 2.2, compiled with Xcode 7.3 and is live on the App Store. The apps utilize Push Notifications and is working fine in iOS 9.3 and earlier.
On devices that have been upgraded to iOS 10, however, my apps don't receive any Push Notifications. Devices that are still running iOS 9 are still receiving notifications.
Thinking it might be a certificate or entitlement issue, I have tried the following: Upgraded one of my apps to Swift 2.3, added the APS Environment Entitlement and compiled it in Xcode 8 but this made no difference.
In my AppDelegate I still have the existing methods to register for push notifications that includes:
let notificationSettings = UIUserNotificationSettings(forTypes: [.Badge, .Sound, .Alert], categories:nil) application.registerUserNotificationSettings(notificationSettings)
This registration seems to be successful even on iOS 10 since Application didRegisterForRemoteNotificationsWithDeviceToken is then called, so I am receiving a token from APNS.
The problem is that when I send a push notification to this device, Application didReceiveRemoteNotification is never called.
Now, here it is said that the methods on UIApplicationDelegate is deprecated on iOS 10 and I should implement userNotificationCenter(:didReceive:withCompletionHandler:) and userNotificationCenter(:willPresent:withCompletionHandler:)
The problem is that I am not ONLY targeting iOS 10. I still need the app to work on iOS 8 and 9 so I doubt that it's the correct approach to implement those methods.
How do I get push notifications for an existing app to continue working on devices that have been upgraded to iOS 10? Do I need to rewrite code? Do I just need to update some certificates or entitlements and recompile in Xcode 8 with some "new" settings?
You can fix an iPhone that's not getting notifications by restarting it or making sure notifications are turned on. You should also make sure your iPhone is connected to the internet so apps can receive notifications. If all else fails, you should try resetting the iPhone — just make sure to back it up first.
Settings > Sounds & Vibration > Do Not Disturb: if this setting is enabled, Push Notifications will not be received. Make sure this is disabled. Settings > General > Background App Refresh: this setting allows the app to run in the background and must be turned on.
An iOS push notification is a message that pops up on an Apple device such as an iPhone. Before receiving push notifications from an app, iOS device users must explicitly give permission. Once a user opts-in, mobile app publishers can send push notifications to the users' mobile devices.
You need a stable internet connection to support all your Apps and their push notifications. Until and unless your iPhone is connected to a strong Wi-Fi network or cellular data, you will not receive notifications instantly.
If you still don't get notifications for a specific app, try these steps: Make sure that the app supports notifications. Go to Settings > Notifications, select the app, and make sure that Allow Notifications is on. If you have notifications turned on for an app but you're not receiving alerts, you might not have Banners selected.
[Solution] Notifications not Working on iPhone 7 1 Simply restart your iPhone. 2 Check if your iPhone is in Silent Mode. 3 Update iOS on iPhone. 4 Check whether or not Do Not Disturb is activated. 5 Check App Notifications. 6 Connect to a stable network. 7 Restore iPhone. See More....
Note: To view the notification setting for all apps at once, you can go to Settings → Notifications → scroll to the Notification Style section. Tap any app to alter the setting.
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.
