How to handle remote notifications when the app is not running - ios

Question

If my app is running on foreground or background this working fine. I am receiving the notifications and save it on the local database. But if the app killed from the background it receives the remote notifications but the following method is not called. And the issue is if I tap any one of the notification,only that notification will saved on the local database.
- (void)application:(UIApplication *)application
didReceiveRemoteNotification:(NSDictionary *)userInfo
fetchCompletionHandler:(void (^)(UIBackgroundFetchResult result))handler
{
[PFPush handlePush:userInfo];
NSLog(#"Received notification: %#", userInfo);
NSString *alertString = [[userInfo objectForKey:#"aps"]valueForKey:#"alert"];
NSLog(#"%#",alertString);
NSString *msgType = [userInfo objectForKey:#"messageType"];
NSString *senderId = [userInfo objectForKey:#"senderId"];
NSString *receverId = [userInfo objectForKey:#"receverId"];
NSString *msg = [userInfo objectForKey:#"message"];
NSString *timeStr = [userInfo objectForKey:#"Time"];
NSLog(#"msg type%# senderId %# receverId %# message %#",msgType,senderId,receverId,msg);
if ([AppDelegate isNetworkReachable]){
if ([msgType isEqualToString:#"CHAT"]) {
Chatmessage *Cmsg=[[Chatmessage alloc]init];
Cmsg.chat_date =timeStr;
Cmsg.chat_image =#"";
Cmsg.chat_message = msg;
Cmsg.chat_Receiver_Id = receverId;
Cmsg.chat_Sender_Id = senderId;
NSLog(#"recid%#",Cmsg.chat_Receiver_Id);
NSMutableArray *arryMsg = [[NSMutableArray alloc]init];
arryMsg = [[DBModelNew database]getChatMessageBasedOnTime:receverId SenId:senderId time_stamp:timeStr message:msg];
if (arryMsg.count == 0) {
[[DBModelNew database]insertmsg:Cmsg];
}
[[NSNotificationCenter defaultCenter]postNotificationName:#"receivedmessage" object:nil];
chatHistory *chatObj = [[chatHistory alloc]init];
chatObj.chat_meta_id = [NSString stringWithFormat:#"%#",senderId];
chatObj.last_send_message = msg;
NSDateFormatter* dateFormatter = [[NSDateFormatter alloc] init];
dateFormatter.dateFormat = #"yyyy-MM-dd HH:mm:ss";
NSString *str=[dateFormatter stringFromDate:[NSDate date]];
chatObj.last_time_stamp = [self dateformat:str];
PFQuery *query = [PFUser query];
[query whereKey:#"objectId" equalTo:senderId];
[query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
if (!error) {
for (NSDictionary *dict in objects) {
[[dict objectForKey:#"ProfilePic"] getDataInBackgroundWithBlock:^(NSData *data, NSError *error) {
if (!error) {
if (data) {
UIImage *image = [UIImage imageWithData:data];
if (image) {
chatObj.fndimage = image;
chatObj.name = [dict objectForKey:#"name"];
[[DBModelNew database]insertChat:chatObj];
[[NSNotificationCenter defaultCenter]postNotificationName:#"receivedNewMessage" object:nil];
}
}
}
}];
}
}
}];
}
}
}

From the Apple docs, if the user hard closes the app it does not call the method.
In addition, if you enabled the remote notifications background mode,
the system launches your app (or wakes it from the suspended state)
and puts it in the background state when a remote notification
arrives. However, the system does not automatically launch your app if
the user has force-quit it. In that situation, the user must relaunch
your app or restart the device before the system attempts to launch
your app automatically again.

If you want to launch specific payload dictionary from viewDidLoad then you simply call the following :
UILocalNotification *localNotif =
[launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];
And you get the userInfo this way:
NSString *msgType = [localNotif objectForKey:#"messageType"];
And now you can act accordingly. This is just for the circumstances you stated in your title. When the app is not 'running' (terminated)
