Push notifications are not working in iOS 9

问题

I have upgraded my devices to iOS 9 and my Xcode environment to 7.0 beta. Push notifications are not working in iOS 9?

Here is my code:

  float ver = [[[UIDevice currentDevice] systemVersion] floatValue];

    if(ver >= 8 && ver<9)
    {
        if ([[UIApplication sharedApplication] respondsToSelector:@selector(registerUserNotificationSettings:)])
        {
            [[UIApplication sharedApplication] registerForRemoteNotifications];
            UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert) categories:nil];
            [[UIApplication sharedApplication] registerUserNotificationSettings:settings];

        }
    }else if (ver >=9){

        [[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];

        [[UIApplication sharedApplication] registerForRemoteNotifications];


    }
    else{
        //iOS6 and iOS7 specific code
        [[UIApplication sharedApplication] registerForRemoteNotificationTypes:UIRemoteNotificationTypeBadge|UIRemoteNotificationTypeAlert];
    }

Push notifications are working fine on iOS 8 to 8.3 built with Xcode 6.4.

After adding the code in your project and creating the certificate and Ad-Hoc Profile -

*Just enable this from your X-code*

I ran into the same problem. I solved it by creating an Ad-Hoc Profile. I noticed push is not happening when I use a development profile. And the other thing I noticed was the Device Token gets changed for every fresh install which is kind of weird as we have to update the server for every new instance.

You can go through this article for a better understanding : iOS 9 Push Notifications

write this code in didFinishLaunchingWithOptions

 UIUserNotificationType userNotificationTypes = (UIUserNotificationTypeAlert |
                                                UIUserNotificationTypeBadge |
                                                UIUserNotificationTypeSound);
UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:userNotificationTypes
                                                                         categories:nil];
[application registerUserNotificationSettings:settings];
[application registerForRemoteNotifications];

and add this method to AppDelegate as i have used for parse push notification service

 - (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
  // Store the deviceToken in the current installation and save it to Parse.
PFInstallation *currentInstallation = [PFInstallation currentInstallation];
[currentInstallation setDeviceTokenFromData:deviceToken];
currentInstallation.channels = @[ @"global" ];
[currentInstallation saveInBackground];
}

Please try this code as its working for my IOS 9 application

Write a Code in AppDelegate DidFinishLaunchWithOption

if([[UIApplication sharedApplication] respondsToSelector:@selector(isRegisteredForRemoteNotifications)])
{
    [[UIApplication sharedApplication] registerUserNotificationSettings:  [UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeAlert | UIUserNotificationTypeBadge | UIUserNotificationTypeSound) categories:nil]];

    [[UIApplication sharedApplication] registerForRemoteNotifications];
}
else
{
   #if __IPHONE_OS_VERSION_MIN_REQUIRED < __IPHONE_8_0
    [[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIUserNotificationTypeAlert | UIUserNotificationTypeBadge |    UIUserNotificationTypeSound)]; #endif
}

Make sure the following items are well checked for the Push notification on the server

PEM File generated with selecting the Cert & Private key from the originator
Apple service enabled and pointing to Sandbox/Live correctly
Push notification token is received in below function and not any Error is returned which is well send to the server (LAMP service) that is sending the APNS Push notification to device Token.
Check the Apple APNS response code in the server with the Push send to the token.

Enabled Push notification in the settings as if you do any goof up in the '|' symbol code you may see the sound, badge options not shown in Apple General Notification settings

-(void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
    {
        NSString *devicetokenString = [[[[deviceToken description] stringByReplacingOccurrencesOfString: @"<" withString: @""] stringByReplacingOccurrencesOfString: @">" withString: @""] stringByReplacingOccurrencesOfString: @" " withString: @""]; 

        DLog(@"Did Register for Remote Notifications with Device Token DATA (%@) \n STRING token (%@)", deviceToken,devicetokenString);

        //If Same token received again dont take any action else save in NSUserdefaults or system and send to server to register against this device to send push notification on the token specified here.
    }

-(void)application:(UIApplication *)application    didFailToRegisterForRemoteNotificationsWithError:(NSError *)error 
    {
        DLog(@"Did Fail to Register for Remote Notifications");
        DLog(@"%s:%@, %@",__PRETTY_FUNCTION__,error, error.localizedDescription);
    }

-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
    {
        DLog(@"Did Receive for Remote Notifications with UserInfo:%@", userInfo);
    }

Hope this is well explained if any help do post your updated code so we can help you.
