使用UNUserNotificationCenter后未调用didReceiveLocalNotification
我正在安排本地通知。 它适用于iOS 9.x但是从iOS 10开始
-(void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification 应用程序在iOS 10上运行时不会调用。
我知道iOS已经引入了新的UserNotifications框架，但不应该停止使用iOS 9 API。
我该如何解决这个问题？
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何时显示或点击通知。
[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，如果您仍想使用旧的（已弃用的） application:didReceiveLocalNotification application:didReceiveRemoteNotification:fetchCompletionHandler和application:didReceiveRemoteNotification:fetchCompletionHandler ，解决方案很简单：只是不要将任何委托设置为UNUserNotificationCenter 。
请注意，静默远程通知（包含content-available密钥且没有alert ， sound或badge alert ）始终由application:didReceiveRemoteNotification:fetchCompletionHandler处理application:didReceiveRemoteNotification:fetchCompletionHandler ，即使您已设置委托。
