The user force killed the application and then receives 3 push notifications from the server.
When clicking on the push notification, the application will relaunch.
Is it possible to read user info dictionary of all push notifications available in the notification bar for that particular application?
No, it is not possible. You need to implement a web service.
The web service will provide all unread notifications.
If your application isn't running then only the notification that the user actually tapped on will be delivered to your application in didFinishLaunchingWithOptions. The content of the other notifications is not available.
If the user launches your application from the app icon rather than from the notification then no notification information is available.
Your app should retrieve any updates whenever it is launched, regardless of the availability of notification data in didFinishLaunchingWithOptions. The presence of notification data should act as a hint as to the behaviour the user is expecting from your app (for example, if they tapped a notification that they had received a message from a specific user they would probably expect the app to open to that message).
Yes it is possible to read the push notification by clicking it from the navigation controller.
First of all when application is open it comes in didFinishLaunching method. And if you trying to open application from the navigation push notification click then you can get the notification in launchOptions variable. It contains the dictionary regarding the Pushnotification.
You can find it by below code.
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
NSDictionary *userInfo = [launchOptions valueForKey:#"UIApplicationLaunchOptionsRemoteNotificationKey"];
NSDictionary *apsInfo = [userInfo objectForKey:#"aps"];
if(apsInfo) {
//there is some pending push notification, so do something
}
}

I am making a certain application.
Which has these functions.
1 This application has push notification.
2 This application can stock the push notification log when it is active.
3 This application can stock the push notification log when it is not active.
1,2 is OK for me. 1 is normal, 2 is accomplished by push notification callback.
However 3...?
I guess on Android background job works and get the notification.
but is it impossible on iOS?
In addition to the previous answer: about didFinishLaunchingWithOptions.
This only works when the program is launched by clicking on the notification/push message window. But if you run the app directly, by clicking on the app icon, even when the notification/push message arrives, you will not receive any data in launchOptions about push message.
So about the paragraph 3: you can know it only if user tap on push message window/bar.
When the application is not active, you can handle the push notification using didFinishLaunchingWithOptions delegate method:
UILocalNotification *localNotif = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
if (localNotif) {
NSString *json = [localNotif valueForKey:#"data"];
// Parse your string to dictionary
}
I have a problem with push notifications in iOS, in a similar scenary to this and this and another one.
Also, this post resume all possible situations.
In my case:
app is NOT RUNNING
content-available:1
UIBackgroundModes contains 'remote-notifications' and 'fetch'
If the user force-quit the app and receives a push notification, then it could open app from alert or from icon.
When the user tap on the notification the app will be opened and the following method will be executed:
- (BOOL) application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Handle for notifications when app is closed
if (launchOptions) {
NSDictionary *userInfo = [launchOptions valueForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
NSDictionary *apsInfo = [userInfo objectForKey:#"aps"];
if (apsInfo) {
// handle notification
}
}
No problem up to here, I have the payload to doing something with that info (for example to fetch new data from server).
But if the user open the app from the icon I don't have any way to handle the payload (Although didFinishLaunchingWithOptions is execute, I don't have the aps info, according to docs here).
So, the question is, there are any way to solve that?
For example, I made the test with WhatsApp, and they handle that situation, (probably they are using VOIP notifications instead of Remote Notifications)

You should never assume that state has remained consistent between the time the notification has been delivered and the time the user has launched the app. Nor, even, that it is the same device. I'll frequently get a "Hey! Do something!" notification on my phone and, if my iPad is handy, respond to it on my nice big iPad screen.
Instead, you should round trip to the server and grab the most up to date state for that user at the time of app launch or activation.
I’m able to send and receive the push notification…In the push notification i will be sending some json encoded data…
Once my device receives the push notification,then if the user taps on the notification banner device can get the json data received by the push notification.…But what if user clears the notification banner,how can the iOS device receive the json data?…Any suggestion guys?…
You can set the content-available flag to 1 and iOS will call your app's delegate.
There are just 2 ways to get push notification details, when application is not working. First one is not very reliable since it will provide you latest push notification only. Second one, you can't really use if you want banner and you want to notify user. Third one is just an alternate way to get latest updates from server.
Get details of last push notification in application Launch method :
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
NSDictionary *dicAPNS = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
Use silent Push notification, where user wont get any notification but you will be able to get notified. This is done by sending "content-available:1" in APNS Payload.
Call an server call to check if you have any update. So you can grab data from server what you might have received in missed push notification.
I think iOS push notification fully depends on user's wish.I think the another web service needs to load all the content of data in push notification, if push notification is disabled or deleted by user.
I have received push notification, if i open the push notification then didReceiveRemoteNotification is calling and i am getting the notification information, instead of if i clear the notifications and open the app then didReceiveRemoteNotification is not getting called. How to resolve this?
If you open the app from the launch icon (instead of opening it from the push notification), didReceiveRemoteNotification will not be called and you'll have no way to access the notification data. It doesn't matter if you clear the notifications or not.
If the action button is tapped (on a device running iOS), the system launches the application and the application calls its delegate’s application:didFinishLaunchingWithOptions: method (if implemented); it passes in the notification payload (for remote notifications) or the local-notification object (for local notifications).
If the application icon is tapped on a device running iOS, the application calls the same method, but furnishes no information about the notification.
As Eran pointed out, if You're opening the app from the Icon that callback will not be called. I don't know if the notification is totally removed when You delete it from the notification center list, but if the app is not running and has been launched by tapping on the notification, you can check for the notification in the launchOptions at the startup:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary
*)launchOptions {
NSDictionary *notif = [launchOptions objectForKey: UIApplicationLaunchOptionsRemoteNotificationKey];
if (notif) {
//handle your notification here
}
return YES;
}
I'm setting up Apple push notification for my iOS app.
If several notification are received when the app is not running (or in background), how can all received notifications be taken into account when the app (re)starts ?
In iOS 5 the push notifications accumulate in the tray.
In application:didFinishLaunchingWithOptions:
use UIApplicationLaunchOptionsRemoteNotificationKey. This will give you the notification dictionary.
May be this can help you -
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
NSDictionary* dictionary = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
}
There is no way of getting push notifications programmatically.
The only way to handle these notifications is to implement application:didFinishLaunchingWithOptions: which will contain data about the notification that the user tapped.
The good way to achieve what you want is to have a web service of your own that you call when your application enters foreground.
