本地通知不适用于某些用户（iOS 8）

我有一个使用本地通知的应用程序和ti曾经在以前的版本中工作正常。 我已经更新了iOS 8的应用程序并进行了测试并且运行良好。 在向app store提交更新后，少数用户抱怨他们没有收到任何本地通知。 但是，我检查过的大量用户都很好，并且没有发现任何问题。

对于有错误的用户（至少其中一个），他们无法在“设置 – > myApp”屏幕中看到“通知”项目; 缺少整个选项而不是禁用它。 “位置”和“使用蜂窝数据”在该屏幕中，但不在通知中。 我试图更改“设置 – >通知 – > myApp”下的设置，它按预期工作。

有关如何调试此问题的任何建议都将非常有用。 谢谢！

尝试使用Objective-C：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions: (NSDictionary *)launchOptions { // are you running on iOS8? if ([application respondsToSelector:@selector(registerUserNotificationSettings:)]) { UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeBadge|UIUserNotificationTypeAlert|UIUserNotificationTypeSound) categories:nil]; [application registerUserNotificationSettings:settings]; } else // iOS 7 or earlier { UIRemoteNotificationType myTypes = UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound; [application registerForRemoteNotificationTypes:myTypes]; } } 

对于Swift：

 func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: NSDictionary?) -> Bool { // Override point for customization after application launch. if(UIApplication.instancesRespondToSelector(Selector("registerUserNotificationSettings:"))) { application.registerUserNotificationSettings(UIUserNotificationSettings(forTypes: UIUserNotificationType.Sound | UIUserNotificationType.Alert | UIUserNotificationType.Badge, categories: nil)) } else { // } return true }

首先，您必须注册使用本地推送通知

 UIApplication *application = [UIApplication sharedApplication]; if ([application respondsToSelector:@selector(registerUserNotificationSettings:)]) { [application registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert|UIUserNotificationTypeBadge|UIUserNotificationTypeSound categories:nil]]; } 

然后你可以发送本地推送通知

  UILocalNotification *notification = [UILocalNotification new]; notification.alertBody = @"Local Push !!!"; notification.applicationIconBadgeNumber=1; [[UIApplication sharedApplication] presentLocalNotificationNow:notification];

 void EnableLocalNotificationIOS8 { UIApplication *app = [UIApplication sharedApplication]; if ([app respondsToSelector:@selector(registerUserNotificationSettings:)]) { UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert | UIUserNotificationTypeBadge | UIUserNotificationTypeSound categories:nil]; [app registerUserNotificationSettings:settings]; [app registerForRemoteNotifications]; } }
