I'm developing a chat application, i want to rewrite Push Notification Content (alert) in iOS.
Suppose the alert came is: +911234567890 : Hi how are you
In this alert +911234567890 is the contact number in my phone named My Tester, i just want to rewrite the push notification to: My Tester : Hi how are you
How it can be implemented
This needs to work if the app is not running also.
May sample code is below for process push:
(void)application:(UIApplication )application didReceiveRemoteNotification:(NSDictionary )userInfo fetchCompletionHandler:
(void (^)(UIBackgroundFetchResult))completionHandler
In push notification you can display those content that is received by the push notification. If you want display name with push notification then you have to send it from server.Even you can show in Whats App, Whats App notification doesn't show actual name we have store in phone book.It only show the name which is send by the server

I am sending remote push notifications using APNS. The requirement is when the notification is delivered to the app user (even if the user did not tapped on the notification or even seen it) , send a delivery receipt to the web server (i.e. call a web service) according to the notification id i received.
APNS did not have a provision of delivery reports. Their is a feedback service of APNS, however that does not offer delivery report either.
So i would like to know what are the possible ways to get a delivery report of remote push notifications. If i am able to execute a custom method in APP deligate or any other when a remote push notification arrives even when the APP is in background or terminated by user then it will solve my problem.
Any help will be highly appreciated.
Below is the code i am using currently and it is not working when the app is in background.
I wrote a custom method in
-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
to send confirmation to the server that the notification is received. When the application is in foreground all functions execute perfectly. But the problem arise when the application is in background. The custom method which is written in
-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
does not execute until the user open the application by tapping the notification bar and never execute if the user open the application by tapping the app icon not by the notification bar.
Since Apple doesn't provides any method to know when a Push Notification has delivered to user's device. Here is what you can do,
1) Add "Notification Service Extension" to your app.
2) Now add your code for calling webservice to report to your server about the Notification being received, in didReceiveNotificationRequest.
3) Now go to Capabilities of your app and enable "Background fetch" in "Background Modes".
4) Now with the notification you are sending, pass "content-available = 1", This will wake up your app for 30 sec and it can execute the code written in didReceiveNotificationRequest.
It worked for me.
Why do you need to know this? What purpose does it serve you to know whether or not they actually received the notification on their device?
In any case, use: https://developer.apple.com/library/content/documentation/NetworkingInternet/Conceptual/RemoteNotificationsPG/CreatingtheNotificationPayload.html#//apple_ref/doc/uid/TP40008194-CH10-SW8
It will wake your app for 30 seconds in the background to handle it. You need to add the RemoteNotifications background capability.
If too many are sent per hour, Apple will throttle them or just not deliver them.
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.
When the push notification arrived, user click the app directly , the push notification remain in notification center. how can i get the message from notification center ? i want to get it and save it locally so users can view them later.
I can save the push notification if i click the alert from the notification center when the push notification arrived. or i can save the push notification when the app is running.
in AppDelegate.m
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
[PFPush handlePush:userInfo];
//save the alert
[FunctionNSObject savePushNotification:userInfo];
}
in MyTableViewController.m
- (void)viewDidLoad
{
[super viewDidLoad];
//load push notification from file
sortedMessages = [FunctionNSObject loadPushNotification];
}
you can add below code in didFinishLaunchingWithOptions
if ([[launchOptions allKeys] containsObject:UIApplicationLaunchOptionsRemoteNotificationKey]) {
id userInfo=[launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
}
this method call when application is close and click on notification and you only get this notification info
Your reasoning is flawed--push notifications are meant to be transient, they can be tied to an event (such as an email being received) but they are not the event itself. In the email example, all the push is supposed to do is to tell the email app that there is a new email and maybe contain some content that will give a hint to the email content, but the actual content of the email is not the job of the notification to deliver--that needs to be fetched separately. APNS is a system for sending events to remote clients, it is not the content system itself.
The way systems like Facebook or whatsapp deal with this is that they have their own message system and they use APNS to inform the applications that there is a new message in the inbox, then the app will fetch the content for the user by pulling it from the server.
If you want to build a system like this then you can still use APNS but APNS should inform your client that there is new content available to fetch and you will need a server that manages the cloud inbox.
I am working on a app, where I need to send a push notification to the app to start processing data as needed.
How do I send a push notification to the device so that instead of showing the alert message, the notification is forwarded to the app - whether the app is in the foreground or background..
I did implement the delegate method :
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler
however this is called only when the app is in the foreground. When the app is in the background the notification shows up on the notification center.
Please advice.
To make this works you need to do few step:
set background mode remote-notification
implement application:didReceiveRemoteNotification:fetchCompletionHandler: method in app delegate
and make sure push notification payload contains key "content-available" : 1

Is your application using a backend? An example would be Parse or another to store your data.
Parse, for example, allows you to add push notifications that can be customized and changed to get the most out of your application.
I installed Parse sdk on my iphone app. This is for xcode 4.5.
I get the modal request to enable push notifications.
The subscription is successful. The token shows up on the parse web app.
Says 1 user subscribed.
But I dont get a notification from the web app.
I just cant understand what to do here.
All the provisioning madness should be correct.
Was done for development.
I am using the below code to listen for the notifications.
But never gets fired. What am i doing wrong here???
- (void)application:(UIApplication *)application
didReceiveRemoteNotification:(NSDictionary *)userInfo {
NSLog(#"received push %#", userInfo);
[PFPush handlePush:userInfo];
}
Check your app's push notification page in the Parse dashboard, which should be at https://www.parse.com/apps/(your app)/push_notifications. If the push notification doesn't appear there, then your notification didn't get sent, and the problem is on the web app's side.
Try sending the push notification while your app isn't running. If you get the notification, then it's something in your app. If you don't get the notification, then you must have set up the push notification incorrectly somewhere.
Also, Parse has a pretty detailed tutorial.
