didReceiveLocalNotification在使用UNUserNotificationCenter后未被调用

Question

我正在安排本地通知。它在iOS 9.x中工作，但从iOS 10开始

-(void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification

当应用程序在iOS 10上运行时不会被调用。

我知道iOS引入了新的UserNotifications框架，但这不应该停止iOS 9 API的工作。

我怎样才能解决这个问题？

如您所知，iOS 10引入了UNUserNotifications框架来处理本地和远程通知。使用此框架，您可以设置委托以检测通知何时出现或被窃听。

[UNUserNotificationCenter currentNotificationCenter].delegate = yourDelegate;

..。

// In your delegate ...

- (void)userNotificationCenter:(UNUserNotificationCenter *)center
       willPresentNotification:(UNNotification *)notification
         withCompletionHandler:(void (^)(UNNotificationPresentationOptions))completionHandler {

    // Notification arrived while the app was in foreground

    completionHandler(UNNotificationPresentationOptionAlert);
    // This argument will make the notification appear in foreground
}

- (void)userNotificationCenter:(UNUserNotificationCenter *)center
didReceiveNotificationResponse:(UNNotificationResponse *)response
         withCompletionHandler:(void (^)())completionHandler {

    // Notification was tapped.

    completionHandler();
}

现在，如果您仍然希望使用旧的(不推荐的) application:didReceiveLocalNotification和application:didReceiveRemoteNotification:fetchCompletionHandler，解决方案很简单:只是不将任何委托设置为UNUserNotificationCenter。

请注意，即使设置了委托，静默远程通知(那些包含content-available键而不包含alert、sound或badge的通知)始终由application:didReceiveRemoteNotification:fetchCompletionHandler处理。
