What to do if extension parameters for iOS notifications cannot be retrieved

The following examples show how to retrieve notification extension parameters from the iOS notification payload.

1. // Push an iOS notification using the advanced OpenAPI interface.

2. PushRequest pushRequest = new PushRequest();

3. pushRequest.setAppKey(appKey);

4. pushRequest.setTarget("DEVICE");

5. pushRequest.setTargetValue("xxxxxx");

6. pushRequest.setPushType("NOTICE");

7. pushRequest.setDeviceType("iOS");

8. pushRequest.setTitle("Push Title");

9. pushRequest.setBody("Push Body");

10. // Pass the notification extension properties in a JSON map format.

11. // In this example, the extension properties are key1=value1 and key2=value2.

12. pushRequest.setiOSExtParameters("{\"key1\":\"value1\",\"key2\":\"value2\"}")

The following examples show how to retrieve the extension parameters on the client.

For devices running iOS 10 or later:

1. - (void)handleiOS10Notification:(UNNotification *)notification {

2. UNNotificationRequest *request = notification.request;

3. UNNotificationContent *content = request.content;

4. NSDictionary *userInfo = content.userInfo;

5. // Notification time

6. NSDate *noticeDate = notification.date;

7. // Title

8. NSString *title = content.title;

9. // Subtitle

10. NSString *subtitle = content.subtitle;

11. // content

12. NSString *body = content.body;

13. // Badge

14. int badge = [content.badge intValue];

15. // Retrieve the content of custom notification fields. For example, retrieve the content for the keys "key1" and "key2".

16. NSString *extKey1 = @"key1";

17. NSString *extKey2 = @"key2";

18. NSString *extValue1 = [userInfo valueForKey:extKey1];

19. NSString *extValue1 = [userInfo valueForKey:extKey1];

20. // Report that the notification was opened.

21. [CloudPushSDK sendNotificationAck:userInfo];

22. NSLog(@"Notification, date: %@, title: %@, subtitle: %@, body: %@, badge: %d, extras: [%@ = %@, %@ = %@].", noticeDate, title, subtitle, body, badge, extKey1, extValue1, extKey2, extValue2);

23. }

iOS 10

1. - (void)application:(UIApplication*)application didReceiveRemoteNotification:(NSDictionary*)userInfo {

2. NSLog(@"Receive one notification.");

3. // Retrieve the Apple Push Notification service (APNS) notification content.

4. NSDictionary *aps = [userInfo valueForKey:@"aps"];

5. // content

6. NSString *content = [aps valueForKey:@"alert"];

7. // Badge count

8. NSInteger badge = [[aps valueForKey:@"badge"] integerValue];

9. // Play sound.

10. NSString *sound = [aps valueForKey:@"sound"];

11. // Retrieve the content of custom notification fields. For example, retrieve the content for the keys "key1" and "key2".

12. NSString *extKey1 = @"key1";

13. NSString *extKey2 = @"key2";

14. NSString *extValue1 = [userInfo valueForKey:extKey1];

15. NSString *extValue1 = [userInfo valueForKey:extKey1];

16. NSLog(@"content = [%@], badge = [%ld], sound = [%@], Extras = [%@ = %@, %@ = %@]", content, (long)badge, sound, extKey1, extValue1, extKey2, extValue2);

17. // Clear the iOS badge.

18. application.applicationIconBadgeNumber = 0;

19. // Report that the notification was opened.

20. // [CloudPushSDK handleReceiveRemoteNotification:userInfo]; // Deprecated since v1.8.1

21. [CloudPushSDK sendNotificationAck:userInfo];
