can you answer a push notification with your voice? So when you iPhone is locked and you get a push notification, can you react to it with you voice?
You're not registered for audio push notifications in your app. Just register for it like this in your App Delegate:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
//Whatever you have already in your app delegate...
// Let device know you're going to be sending one of these types of notifications.
[[UIApplication sharedApplication] registerForRemoteNotificationTypes:
(UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)];
return YES;
}
The 5 types are:
UIRemoteNotificationTypeBadge
UIRemoteNotificationTypeSound
UIRemoteNotificationTypeAlert
UIRemoteNotificationTypeNone
UIRemoteNotificationTypeNewsstandContentAvailability
Here's the documentation: Registering for Remote Notifications

Hope that helps!
You can not play voice in push notification.Push notification Payload not contain your voice.
Users see notifications in the following ways:
Displaying an alert or banner
Badging the app’s icon
Playing a sound.

I was trying to fetch remote notification info when the app was not running,so I was told that I can get from :
UILocalNotification *localNotification = [launchOptions
objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey]
in method:
- (BOOL)application:(UIApplication *)application
didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
,but still can't get info.
Then I use alertView to show the info on iPhone(launch without Xcode),still can't get the info.
Any other issue would cause this? Please let me know if you have any ideas.
How to retrieve and handle remote notifications:
app is running
The userInfo in below method already includes the push notification
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
{
}
app not running
The value for key in launchOptions includes the push notification,under two circumstance:
1.screen is locked,when receive the remote push notification,screen is lighted and user unlock the screen then directly launch the app.
2.user tap on the notification on the drop-down menu to launch the app.
If user tap on the app directly,then the notification will be gone and missed.
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
[launchOptions valueForKey:UIApplicationLaunchOptionsRemoteNotificationKey] description];
}
That key is only in the launch options when the user starts your app from the notification (e.g. taps on it in notification center). Incidentally, I don't think a remote notification would be the class you're using (UILocalNotification).
If your app wasn't in the foreground when the device received the push, and the user didn't launch your app from the notification, the notification is gone. You have to check your own servers to see if you missed anything.
Is there a way to update the number in the badge without showing an alert or opening the app?
I am writing an app that should always display the current number of unread messages in the icon badge, but I want to do so without displaying any alerts to the user.
I am developing for iOS 5.0+.
EDIT: To be more clear, I am asking about a way to do this when the app is not running. I want the server to push a new badge number without showing an alert.. Is this possible?
You can do it.
It is possible to send a push notification without an alert.
You can even register your application just to badge notifications, in which case the provider server won't even be able to send alerts or sounds.
The Notification Payload
Each push notification carries with it a payload. The payload
specifies how users are to be alerted to the data waiting to be
downloaded to the client application. The maximum size allowed for a
notification payload is 256 bytes; Apple Push Notification Service
refuses any notification that exceeds this limit. Remember that
delivery of notifications is “best effort” and is not guaranteed.
For each notification, providers must compose a JSON dictionary object
that strictly adheres to RFC 4627. This dictionary must contain
another dictionary identified by the key aps. The aps dictionary
contains one or more properties that specify the following actions:
An alert message to display to the user
A number to badge the application icon with
A sound to play
Note that it says one or more of the properties. The alert property is optional. You can even send a notification with an empty aps dictionary (i.e. send only custom properties).
Example 5. The following example shows an empty aps dictionary;
because the badge property is missing, any current badge number shown
on the application icon is removed. The acme2 custom property is an
array of two integers.
{
"aps" : {
},
"acme2" : [ 5, 8 ]
}
The only alert the user will see it the alert that asks him/her whether to allow push notifications. That alert will only be displayed the first time the app is launched after installation.
In this example you register to non alert notifications (badges and sounds only) :
Listing 2-3 Registering for remote notifications
- (void)applicationDidFinishLaunching:(UIApplication *)app {
// other setup tasks here....
[[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound)];
}
// Delegation methods
- (void)application:(UIApplication *)app didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)devToken {
const void *devTokenBytes = [devToken bytes];
self.registered = YES;
[self sendProviderDeviceToken:devTokenBytes]; // custom method
}
- (void)application:(UIApplication *)app didFailToRegisterForRemoteNotificationsWithError:(NSError *)err {
NSLog(#"Error in registration. Error: %#", err);
}
All quotes are taken from the Apple Local and Push notifications programming guide.
you should use applicationIconBadgeNumber for locally handling your app badge number
[UIApplication sharedApplication].applicationIconBadgeNumber = number_of_notifications;
I don't think it is possible to do without alert as far as adding badge counter from remote notification. You should read about APN Service, in your case you might register for UIRemoteNotificationTypeBadge you should read about Local & Push Notification Programming guide
You can use
[UIApplication sharedApplication].applicationIconBadgeNumber = aNumber;
-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
{
[[UIApplication sharedApplication] setApplicationIconBadgeNumber:0];
}
use this method....this will help u.
I am working on one iPhone app which involves a push notification. As I have seen in many documents and tutorials it suggests to register for push notification with in
application:(UIApplication *)application
didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
like the following:
- (BOOL)application:(UIApplication *)application
didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
[[UIApplication sharedApplication] registerForRemoteNotificationTypes:UIRemoteNotificationTypeAlert| UIRemoteNotificationTypeBadge| UIRemoteNotificationTypeSound];
...
}
now the question is, if the app was not running (even in background), when the push come, it cant process the push message, but if I use the push message again from the notification area and lunch the app again, I can get my message.
what I need to do to make my app get the push message even when it lunch for the first time?
You might be conflating the notion of registering for and receiving notifications. It is impossible for an app to receive a push notification before the registerForRemoteNotificationTypes: method is called the first time, since this method provides the push token that is used to send push notifications in the first place.
So, you must be talking about receiving notifications under the two separate situations in which they can be delivered: upon initial app launch, and during the execution of the program.
In order to handle notifications of the first type, you must inspect the options dictionary sent to application:didFinishLaunchingWithOptions:. The following code shows how to route a notification received at launch to the delegate method that is called when a push notification arrives while the app is already running.
Place this in your application:didFinishLaunchingWithOptions: override:
NSDictionary *pushNotificationPayload = [launchOptions valueForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
if(pushNotificationPayload) {
[self application:application didReceiveRemoteNotification:pushNotificationPayload];
}
I am implementing push notification for a client. I have followed all the steps of push notifications setup on device (including certificate generation and everything).
I have used following links as reference:
Apple Push Notification Services Tutorial
Programming Apple Push Notification Services
I call this function in app delegates didFinishLaunchingWithOptions
[[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)];
After setup, i run the app i get the Blue Push notification warning dialogue but after I press Ok the delegates are not called.
- (void)application:(UIApplication*)application didFailToRegisterForRemoteNotificationsWithError:(NSError*)error
- (void)application:(UIApplication*)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData*)deviceToken
None of these delegates are called ever. I am stuck here as i cannot proceed further as none of the delegates is called.
If any of you has faced a similar issue i would be very very thankful if you can help me out here.
I have seen this before, you need to just add [application registerForRemoteNotifications]; to your code, where application is the instance of UIApplication inside the didFinishLaunchingWithOptions method of the app delegate. Make sure you add this once you have set up your UINotificationType, and UIUserNotificationSettings
As i said in the title of this thread, I have a problem with Push notification of my application.
There is 2 cases :
When the app asks you if you want push notification and you push OK, it's working great.
This function :
- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)devToken
is called when registerForRemoteNotificationTypes is called :
- (void)applicationDidFinishLaunching:(UIApplication *)application {
// Add registration for remote notifications
[[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound)];
...
}
But when you select NO at the beginning, and then you change your settings to accept push notification, nothing append and this function didRegisterForRemoteNotificationsWithDeviceToken is never called.
Please help me, i'm getting crazy!
I see you register for remote notifications in:
- (void)applicationDidFinishLaunching:(UIApplication *)application
If your application is running on a iOS device with support for multitasking that might not be the right place.
The above method is called when you initially launch your app from cold. This is when you are prompted to accept or decline Push Notifications - and in your case decline.
When you later exit the application to change the settings in the device wide control panel the application is not quit - it is merely resigning as the foreground application. When you have enabled Push Notifications in the control panel and return to your application - the application is not launched again but moves from being backgrounded to the foreground.
Your application delegate will at this point receive an:
- (void) applicationDidBecomeActive:(UIApplication *)application
try registering for Push Notifications there instead using:
- (void)registerForRemoteNotificationTypes:(UIRemoteNotificationType)types
You could also prevent backgrounding by setting the “Application does not run in background” property in the application’s Info.plist file (UIApplicationExitsOnSuspend).
