Registering the iPhone application for push notification not working

Question

I have tried out the example found in the link http://www.raywenderlich.com/3443/apple-push-notification-services-tutorial-part-12 , for my iPhone push notification message. I could successfully run all steps except the steps for registering the app for push notification for the first time.

I have followed different variations of the code:

[[UIApplication sharedApplication] registerForRemoteNotificationTypes:
(UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)];

But none worked for me. I am testing it in my iPhone 4 and my Xode version is 4.2 , OS is Lion. Please advice.

Answer 1

You can try the following:

• Make sure your Xcode project is configured to use the explicit bundle ID from the provisioning portal
• Make sure you're not building the target with wildcard or team provisioning profile, check this on the project AND target settings
• If you created your provisioning profile before configuring the app ID for push, regenerate the provisioning profile

Also look at the error object in the UIApplicationDelegate method

application:didFailToRegisterForRemoteNotificationsWithError:

EDIT 1

Open your provisioning profile in a text editor and look for the string

<key>aps-environment</key>

If your profile does not contain this, it is not correctly set up for push.

Answer 2

Here is my workin code sample from application delegate (AppDelegate.m)

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    [application registerForRemoteNotificationTypes:UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound];
}

To check if registration went OK, implement these three methods

– application:didReceiveRemoteNotification:
– application:didRegisterForRemoteNotificationsWithDeviceToken:
– application:didFailToRegisterForRemoteNotificationsWithError:

http://developer.apple.com/library/ios/#documentation/uikit/reference/UIApplicationDelegate_Protocol/Reference/Reference.html

Or you can go to Settings to see if there is permissions settings available
