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.

Solution 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.

Solution 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

like this:

Solution 3

If this problem appears in production (with your application on the appStore), it's very likely because you created/enabled the APNS production mode of your application AFTER having created the distribution profile.

In this case, no other option but to submit again with a correct certificate...

Rule of thumb: ALWAYS enable/create production certificate for your application BEFORE creating the distribution profile.

You can use the method described by 'nduplessis' (see below) to manually check if you application will run notification once approved.

yes,I have these methods. And also, I have app id with push notification services enabled.

[Vinod]

I have set push notification services under my app id.

[Vinod]

I have added above 3 methods, then I am getting the error in the console "Failed to get token, error: Error Domain=NSCocoaErrorDomain Code=3000 "no valid 'aps-environment' entitlement string found for application" UserInfo=0x143bc0 {NSLocalizedDescription=no valid 'aps-environment' entitlement string found for application}" But the app is running on iPhone with a blank white screen. Also, I have not started the payload/php part of the code.

[Vinod]

1) yes, I have the explicit bundle id 2) I am not using wild cards, 3) I have regenerated provision profile and tried to run the app again.

[Vinod]

I have added NSlog printing for each method, I could get the output from the method "didFinishLaunchingWithOptions" only, and then the above error.

[Vinod]

I am getting the NSlog output for the method "didFinishLaunchingWithOptions" not for others . Now I am getting the error Failed to get token, error: Error Domain=NSCocoaErrorDomain Code=3000 "no valid 'aps-environment' entitlement string found for application" UserInfo=0x1657c0 {NSLocalizedDescription=no valid 'aps-environment' entitlement string found for application}

[nduplessis]

What error are you getting in the delegate method mentioned above?

[Marek Sebera]

@Vinod great, now when you do have error response, you can find where the problem is. Read this: stackoverflow.com/questions/5681172/…

[jodm]

Check you are building against the correct provisioning file. Sounds like the problem to me. You would have had to create a provisioning file against the app Id with push notifications.

[Vinod]

Thank for your point, I have opened the file with extension .mobileprovision, It do not have the line "<key>aps-environment</key>", I think I have to redo the steps and check again.

[Vinod]

Hi Marek, thanks for the link. This is my first app in Iphone. I have one question. I have created a CSR for my first Hello world app for the device. But at that time I have ticked the checkbox "Key pair information" under Certificate assistant. But push notification tutorials do not show it as checked. Should I ticke that checkbox? Should I create separate CSR for each app ?

[Vinod]

Should I create separate CSR for each iphone app ?

[Vinod]

I have recreated the provisioning profile and its working fine now. As you told the problem was with this file. Thanks all.

[nduplessis]

Happy to hear it. If you find that this answer was the one that solved your problem, please consider accepting it as the correct answer

[Marek Sebera]

@Vinod you're super brave, if your first application ever should use APNS. But really, this question is out of scope of this thread. Create another question, if you're having difficulties with APNS.

[zirinisp]

In my case I was using the wildcard provisioning profile and that was the problem. Apple can be very complicated some times.

[AVEbrahimi]

@Vinod No, one CSR is enough
