What are the steps in implementing Apple Push Notification?

Question

I am new to this topic and require some guidance in implementing Apple Push Notification in my application. I have created my appID and also configured Apple Push Notification for the same. I have downloaded the provisioning profile and installed the app on the iphone. I have also written the following code provided by Apple documentation

- (void)application:(UIApplication *)app didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)devToken
{
    const void *devTokenBytes = [devToken bytes];
    NSLog(@"devToken=%@",devTokenBytes);
    //self.registered = YES;
    //[self sendProviderDeviceToken:devTokenBytes]; // custom method
}

- (void)application:(UIApplication *)app didFailToRegisterForRemoteNotificationsWithError:(NSError *)err
{
    NSLog(@"Error in registration. Error: %@", err);
}

I want to know what I have to write on the server side. When I run the code it says that the device is not registered. How can I register my application for the push notification.

Can anyone help me with this...

Any code will be very helpful...

Thanx in advance...

Answer 1

You need to tell your server about the device token returned by Apple when you register for notifications from the device, so that the server can present the same token and app id when it tells the apple server that there's a new notification. Have you done that? I believe the device token could change each time you register, so you'll need to keep track of that on your server (and tell the server each time).

You've shown the callbacks involved in device registration, but have you actually called the registration method itself?

You also got to listen to didReceiveRemoteNotification in case you want to know when notifications arrive also when the app is in foreground. You might also want to clear the badge number set on the app icon when the user has read the notification it was sent.
