Quickblox 'automatic push notifications for offline user' not working - ios

Question

I have following scenario.
User A sends message to User B in foreground -- this is working
Send push notification to User B, when app is in background, from 'Messages' console -- this is working
I want to send notification alert to User B when app is in background. I read that this is done automatically by quickblox, but is not happening for me.
I have followed instructions on this link
I am using 'Starter' account in development mode. Do we need account with ' server side history' for this functionality?
Edit 1:
Clarification: I want to send 'automatic push notifications for offline user' and not notification from app. I am also sending 'save_to_history' flag as mentioned on the link.

Answer 1

for Sending push notification use below code
-(void)applicationDidEnterBackground:(UIApplication *)application
{
[self sendMessageNotification:#"Hello Push notification" :1234 ];
}
-(void)sendMessageNotification:(NSInteger)recipientID message:(NSString*)message
{
isSentPushNotification = YES;
//[self sendPushNotificationToUser:message ids:#"1" audioFileName:#"default"];
NSMutableDictionary *payload = [NSMutableDictionary dictionary];
NSMutableDictionary *aps = [NSMutableDictionary dictionary];
[aps setObject:#"default" forKey:QBMPushMessageSoundKey];
[aps setObject:message forKey:QBMPushMessageAlertKey];
[aps setObject:#"1" forKey:QBMPushMessageAlertLocArgsKey];
[payload setObject:aps forKey:QBMPushMessageApsKey];
QBMPushMessage *pushMessage = [[QBMPushMessage alloc] initWithPayload:payload];
// Send push to users with ids 292,300,1395
[QBRequest sendPush:pushMessage toUsers:[NSString stringWithFormat:#"%lu",(long)recipientID]successBlock:^(QBResponse *response, QBMEvent *event) {
NSLog(#"Successfully dilivered push notification");
} errorBlock:^(QBError *error) {
NSLog(#"Fail to diliver push notification %#",error);
}];
}
But you should first Subscribe User to receive Push Notifications
- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
{
// Register subscription with device token
[QBRequest registerSubscriptionForDeviceToken:deviceToken successBlock:^(QBResponse *response, NSArray *subscriptions) {
// Registration succeded
} errorBlock:^(QBError *error) {
// Handle error
}];
}
for more detail please have a look of this

Answer 2

Found the problem.
We have to logout from the the chat when the app enters background.
I think, this might be required to let server know that we are actually offline and it should send us push notification instead. (just a guess!!)
I think logout thing was mentioned in documentation as well but I didn't know that it was so important.
