I have a question related to handling notifications but in case of application is closed. In my iOS application I schedule the local notifications, and I successfully handle them when application is either in foreground or background. But when application is closed and I get local notification I can't handle it. I mean after pressing "show" button I have to move the user to a specific window. But I don't know where to put the part of the code which deals with handling.
Any idea???
Thanks in advance.

Check - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions in your app delegate, you should receive dictionary from your notification as launching options, as far as I know.
Try this
I could post some code hear but i think the better way is no copy/paste work. So here is the link after they show single notification, they explain how to handle notifications. tutorial about handling notifications

I am working in XMPP Application.
When I terminate and kill My Application than,
1)User is Not Connected In XMPP Server. User is Offline. But I want User is Connected and Online. Like Whats App(Appliction).
2)I can't get Any Messages From XMPP Server Side at that time,
- (void)xmppStream:(XMPPStream *)sender didReceiveMessage:(XMPPMessage *)message
This method is not call. So, How Can I get Messages ?
And i also implement Pushnotification but in this way same issue Like,When app is Kill and Terminate than,This method is not call,
- (void)application:(UIApplication )application didReceiveRemoteNotification:(NSDictionary )userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult result))handler
So, Please Guide me In Proper Way and Suggest me How to work as like same Whats App(Application).
Also, We can't set VOIP Flag In .plist file Because this way is not Proper and reject by the apple.
My Goal is Only Notification Work As like Whats App.
1)User is Not Connected In XMPP Server. User is Offline. But I want
User is Connected and Online. Like Whats App(Appliction).
Once you closed or minimized WhatsApp the user gets offline (tested on iPhone4s), and messages received in this state are as push notifications.
2)I can't get Any Messages From XMPP Server Side at that time,
(void)xmppStream:(XMPPStream *)sender didReceiveMessage:(XMPPMessage *)message
This method get called only when application is active. So you can not get messages here after you killed your application.
- (void)application:(UIApplication )application didReceiveRemoteNotification:(NSDictionary )userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult result))handler
This method will get called in following scenarios
If your app is active and you got any new push notification.
If your app is in background or killed or not started then system will show only notification on the top bar, once user tapped on notification it will open your application and then the method will get called.
And of course you can not use VOIP.
WhatsApp shows custom notification when user is active in WhatsApp.
You need to send push notification for every message of your conversation. In this case
If user is active then show your custom notification in app.
If user is inactive (i.e. killed or minimized app) then system will show Notification in notification center.
When user taps on notification, system will launch application, and you have to check for app launching conditions (from which source app launched) and according to conditions join server/chat (or groups if you are using group chat).
Once you joined server with your name/nickname, you will get recent chats. You can also get history, you need to specify while joining chat server / group.
Make sure you are disconnecting from server and also from group when your app is getting minimized or killed. Use following methods to disconnect and/or related changes
1. - (void)applicationDidEnterBackground:(UIApplication *)application
2. - (void)applicationWillTerminate:(UIApplication *)application
Hope this will help you, I have implemented same to achieve expected results as WhatsApp.
When your app kill, that time XMPP Deactivate all service.So, you can send webservice to server which can tell - you are offline.
Then after sever can send you Push notification all chat content.
First of all, If your application is terminated then you will receive Push Notification data in
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
in launchOptions dictionary with key
if (launchOptions)
{
if ([launchOptions valueForKey:UIApplicationLaunchOptionsRemoteNotificationKey])
{
// Your code
}
}
Second, you can use background fetch for retrieving user's message, While background fetch you can connect your stream and fetch messages from XMPP server.
NOTE: WhatsApp's (iOS) version, fetches the message as soon as you open the app, it is connecting to the stream and then fetches the messages.
However you can implement your own logic to customize your functionality.
Read the following document it will help you.
http://xmpp.org/extensions/xep-0168.html
We ned to add priority when the presence of user is set as below:
-(void)GoOnline{
XMPPPresence *goOnline = [XMPPPresence presence];
NSXMLElement *priority = [NSXMLElement elementWithName:#"priority" stringValue:#"-1"];
[goOnline addChild:priority];
[xmppStream sendElement:goOnline];
}
Now to know more about priority, it's role and how it works, read the document from above link.
Hope it may help you :)
Check this link and read the Remote Notifications (iOS 7 and Greater) section which is combining the Background Modes and Remote notifications to download content before launching the app.
You will get the idea and you can implement in your preferred language obj-c or swift.
I want to know that if my app is not running in background and push notification arrives then my app will automatically start.
It is kind of emergency message that arrive and open my app even if app is not running in background.
Please refer this link, it is working for me
Implement PushKit and test in development behavior
This link contains all steps to create VoIP notification and please note that this will work on ios 8 and above.
:)
If the app is NOT RUNNING, this is not possible without user intervention.
As i understand a question.
If you want to handle when notification reaches your app insert this method to appdelegate
- (void)application:(UIApplication *)application didReceiveRemoteNotification: (NSDictionary *)userInfo {
//notification reached. open app or do something
}
Yes It is possible. You should use PushKit Voip Push notification and CallKit together. When notification came to device, you can show the IOS default call screen. Then when user answer the call, open your uicontrollerview.
I also want to implement same thing and I searched for this question and I got to know that this kind of facility is available in ios8 and allow us to use pushkit.frame work to do this. Below link is I found some what useful plz refer it and I also referring the same but I m not sure about the result ;)

My understanding is that both local and remote notification in iOS will not be displayed if the application is in the foreground.
However if I open the mail app on my iPhone and check my email, then on some occasions i get a banner shown to tell me I have received emails. This occurs when the email app is in the foreground.
Does anyone know how this is done (preferably on Swift)? Or is this privilege only available for Apple written applications.
Any help would be appreciated.
You should implement - (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo method in your AppDelegate.
If you want to handle them by inflating views or whathaveyou, you need to do it in that particular method.
Hi I am looking for a way to read the Remote PushNotification without the function
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo;
The contra of this function is, I have to click on the Notification, then will call this function, but how can I read the Message if I am clicking the App icon from the Homescreen?
Have someone an Idea?
Many Thanks
Greetings
Simon
There's no way to read push notification data when user touched app icon on home screen.
I wrote a simple messaging system, which allows sending brief messages from web interface to devices, in form of push notification.
On android, everything went well, once device receives notification is sends delivery confirmation receipt back to server, then read acknowledgement. Obviously, delivery confirmation often happens while app is running in background or phone is asleep.
I wrote similar app for iOS. How surprised I was that application: didReceiveRemoteNotification is not called when app is not active!
Is it really impossible to track message delivery without user interaction when app is not active? Others have suggested keeping log of messages on server and sending them when app opens, but this still requires user interaction.
Is there a way around apple restriction on background services? Can I somehow make my app use sound or location service, to allow simple POST request while in background?
In iOS7 you can use push notifications with background fetch, which is a remote notification with the content-available flag set. Example payload: {aps: {content-available: 1}}.
In this case iOS will wake up your app (there are some limitations see: Will iOS launch my app into the background if it was force-quit by the user?).
After your app is woken up you have 30 seconds to send to your server the push notification receipt confirmation.
You'll also have to enable the "Background fetch" capability in the Target background modes and update the AppDelegate to include this method:
- (void)application: (UIApplication *)application didReceiveRemoteNotification:
(NSDictionary *)userInfo fetchCompletionHandler:
(void (^)(UIBackgroundFetchResult))completionHandler
So this requires a bit of work from your side.
I hope this helps.
For iOS there isn't any direct way that provides any info regarding the actual delivery, but I found one workaround which I tried and it is working fine.
Use "Notification service extension", the main use of this is to provide rich notification, so it basically wakes our app whenever new push comes and gives around 30 seconds of time perform our task like download an image to show in the notification. We can use this app wake up feature to call our backend.
So send some unique id with payload and from this method call your backend server with the push id, by this way you can be sure that push notification is delivered into the device.
This will work all state of the application, even in the killed state, so this is full proof and we can rely on this workaround for delivery info.
Reference link: https://developer.apple.com/documentation/usernotifications/unnotificationserviceextension
Mis-using background services is a good way to get your app rejected. Apple are pretty strict on what an app can do in the background.
As a user, if I found out that an app I'd installed was making web requests in the background with no good reason, it would be swiftly deleted!
Push notifications are a one-way message - there is no guarantee that a notification has even been delivered, never mind read. I suggest you read up on the APNS here.
When application is not in Active state application: didReceiveRemoteNotification method won't be called .
If you want track the notification information when application is not in active state follow the below procedure.
application didFinishLaunchingWithOptions: method will be called every time when we open the application
from this method we are getting NSDictionary object called launchOptions. From this launchOptions dictionary we will get the notification data in the form of dictionary for the key UIApplicationLaunchOptionsRemoteNotificationKey
find the code from below:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{
NSDictionary *remoteNotify = [launchOptions objectForKey: UIApplicationLaunchOptionsRemoteNotificationKey];
//Accept push notification when app is not open
if (remoteNotify) // it is only true when you get the notification{
// use the remoteNotify dictionary for notification data}}

Check that out, for th source, click on Developers Page.
If its not apples way, there is no way.
That's where jailbreaking comes in. You might have to make your app jailbreak compatible and take advantage of a lot more power.
I'd say for what your looking for, make a new version of Backgrounder that works they way you need it.
