为推送通知注册 iPhone 应用程序不起作用

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.

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

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.

Answer 4

Go to Capabilities -> Push Notifications . If there are errors then try out this solution!

If Xcode version was changed from 7 to 8 then try out this solution!

Xcode 7 copies the aps-environment entitlement from your provisioning profile. Turning on push notifications on Xcode 8 adds the entitlement both to your provisioning profile and the entitlements file.

Try adding the aps-environment entitlement to your app's entitlements file, or switch the notification capability off and on again.

Answer 5

iOS 14 ?

For those who faced with inability to get token, and double checked all the things mentioned above, and developed on iOS 14, and if you have non-english app title, go to Project - Target - Product Name and replace name by $(TARGET_NAME).

I spent entire week on this bug.

Once again: if your app receives token on iOS12, but can not on iOS14, get rid of non-latin chars in names. They say, including entitlements, but as for me, I've managed to make it work and with cyrillic entitlements. To change Product name was enough.

Answer 6

Have you ever seen the push notification dialog in your app? If you dismiss the dialog it takes 24 hours to reshow. Check this by setting the time on your iPhone ahead by 2 days and see if it shows.

Also have you implemented the delegate methods:

- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {

- (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error {

- (void) application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {

Try putting an NSLog(@"") in the didRegisterForRemoteNotificationsWithDeviceToken and didFailToRegisterForRemoteNotificationsWithError and see it is is getting in there?

Also you require an App Id that is setup for Push notification and you need to have generated the Push notification certificates to send the messages.
