方法未被调用： - （void）application：（UIApplication *）application didRegisterForRemoteNotificationsWithDeviceToken：（NSData *）deviceToken

Question

永远坚持这个，但无法调用以下方法。我可以让手机要求许可，但之后就会卡住。

- (void)application:(UIApplication*)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData*)deviceToken
{
    NSLog(@"My token is: %@", deviceToken);
}

- (void)application:(UIApplication*)application didFailToRegisterForRemoteNotificationsWithError:(NSError*)error
{
    NSLog(@"Failed to get token, error: %@", error);
}

我尝试了很多事情，包括：

1）以下stackoverflow帖子中提供的所有内容：why didRegisterForRemoteNotificationsWithDeviceToken is not called

2）查看Apple的技术说明：https://developer.apple.com/library/ios/technotes/tn2265/_index.html

3）整个教程：http://www.raywenderlich.com/32960/apple-push-notification-services-in-ios-6-tutorial-part-1（希望我的证书都很好）

4）（是的，我有互联网连接）

有没有人有任何可能的解决方案？在过去的2-3天里我一直在绞尽脑汁，并且已经出厂两次重置我的手机，以及更改手机上的日期N ^ e次数以便让通知弹出显示为一遍又一遍地测试。

会喜欢任何帮助！谢谢！

以下是我用来调用...（尝试过其他一些版本）：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    //other stuff not related

    if ([application respondsToSelector:@selector(registerUserNotificationSettings:)]) {
    #ifdef __IPHONE_8_0
        UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:(UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert) categories:nil];
        [application registerUserNotificationSettings:settings];
        [application registerForRemoteNotifications];
    #endif
    } else {
        UIRemoteNotificationType myTypes = UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound;
        [application registerForRemoteNotificationTypes:myTypes];
    }

    return YES;
}

iOS 8引入了注册流程的变更，需要在获得用户许可后明确要求注册远程通知。

您正在调用此代码吗？

[[UIApplication sharedApplication] registerUserNotificationSettings: settings];

在你的应用程序代表中实现这个？

- (void) application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings
{
    [application registerForRemoteNotifications];
}

也就是说，旧的API现已弃用，但如果您计划支持iOS 7，则仍然需要这些API。要支持两者，您可以检查UIApplication是否响应新的选择器：

if ([[UIApplication sharedApplication] respondsToSelector:@SEL(registerUserNotificationSettings:)]) {
    // iOS 8
    [[UIApplication sharedApplication] registerUserNotificationSettings: settings];

    // [[UIApplication sharedApplication] registerForRemoteNotifications] 
    // will be called in your UIApplicationDelegate callback
} else {
    // iOS 7
    [[UIApplication sharedApplication] registerForRemoteNotifications];
}
