英文:
Xamarin.Forms iOS DidReceiveNotificationResponse not called
问题
I am trying to use local notifications in my Xamarin.Forms iOS application. The notification is visible, but when I tap the notification, DidReceiveNotificationResponse is not called at all. The code that manages the authorization is not shown here but it is correct. I have read all the posts here and elsewhere about this problem that seams to be related to a delegate issue (not assigned). Here is my code:
[Register("AppDelegate")]
public partial class AppDelegate : global::Xamarin.Forms.Platform.iOS.FormsApplicationDelegate, IUNUserNotificationCenterDelegate
{
public override bool FinishedLaunching(UIApplication app, NSDictionary options)
{
Popup.Init();
global::Xamarin.Forms.Forms.Init();
UNUserNotificationCenter.Current.Delegate = this;...}[Export("userNotificationCenter:didReceiveNotificationResponse:withCompletionHandler:")]public void DidReceiveNotificationResponse(UNUserNotificationCenter center, UNNotificationResponse response, System.Action completionHandler){if (response.IsDefaultAction){if (response.Notification.Request.Content.UserInfo.ContainsKey(new NSString("remainingTime"))){Locator.GetSharedInstance<IAlertDelayedService>().RaiseOpenAlertDelayedPopupEvent();}}completionHandler();}[Export("userNotificationCenter:willPresentNotification:withCompletionHandler:")]public void WillPresentNotification(UNUserNotificationCenter center, UNNotification notification, System.Action<UNNotificationPresentationOptions> completionHandler){completionHandler(UNNotificationPresentationOptions.Alert);}
}

I have found a solution in a Xamarin.Forms notification sample here.
It uses a UNUserNotificationCenterDelegate derived class to handle the received and tapped notifications.
