iOS 8 推送通知在真实设备上不起作用

Question

我有一个通用应用程序我想将 APN 与 iOS 推送通知一起使用。我的推送通知与 ios 8 及更低版本兼容。当我在模拟器上启动时，推送通知权限对话框可以正常工作。但是当在真实设备上启动时它说；

"Attempting to badge the application icon but haven't received permission from the user to badge the application"

AppDelegate

[[NotificationManager sharedInstance] requestPushNotificationIfNeeded];

NotificationManager - requestPushNotificationIfNeeded

// Refresh the token.
    #if __IPHONE_OS_VERSION_MAX_ALLOWED >= 80000
    if([[UIApplication sharedApplication] respondsToSelector:@selector(registerUserNotificationSettings:)]){
        // iOS 8 Notification
        UIUserNotificationType types = UIUserNotificationTypeSound | UIUserNotificationTypeBadge | UIUserNotificationTypeAlert;
        UIUserNotificationSettings *notificationSettings = [UIUserNotificationSettings settingsForTypes:types categories:nil];
        [[UIApplication sharedApplication] registerUserNotificationSettings:notificationSettings];
    }
    else {
        // Less then iOS 8
        [[UIApplication sharedApplication] registerForRemoteNotificationTypes:
         UIRemoteNotificationTypeAlert |
         UIRemoteNotificationTypeBadge |
         UIRemoteNotificationTypeSound];
    }
#else
    [[UIApplication sharedApplication] registerForRemoteNotificationTypes:
     UIRemoteNotificationTypeAlert |
     UIRemoteNotificationTypeBadge |
     UIRemoteNotificationTypeSound];
#endif

应用程序委托方法

#ifdef __IPHONE_8_0
- (void)application:(UIApplication *)application didRegisterUserNotificationSettings:   (UIUserNotificationSettings *)notificationSettings
{
    TRACE(@"Delegate did");
    //register to receive notifications
    [application registerForRemoteNotifications];
}
#endif

- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
{
    // Using parse.com save push notification token
}

问题

这段代码有什么问题？我尝试了好几天，但徒劳无功。你能指导我解决这个错误吗？怎么了，或者我错过了一些必要的东西？非常感谢。

顺便说一句，我注销了委托方法，只注册了 UIUserNotificationTypeAlert 像这样;

Delegate didRegisterUserNotificationSettings: <UIUserNotificationSettings: 0x17422e2c0; types: (UIUserNotificationTypeAlert);>

您的应用似乎没有适当的 permissions 来生成 push notifications。
根据苹果在这种情况下的建议，我也曾经不得不遵循。请按照以下步骤操作：
1) 卸载应用程序，然后重新启动您的 phone.
2) 转到设置 -> 日期和时间并将日期设置为至少比当前日期提前 1 天。
3) 再次重启您的设备。
4) 现在进入设置，将时间恢复正常。
5) 重启设备。 6) 现在安装应用程序，它会询问您推送通知的权限。如果它仍然不请求权限，请再次重复上述步骤，但在第 4 步之后不要重新启动，只需安装应用程序然后重新启动即可。
我希望这能解决您的问题。
