Я реализовал push-уведомление в своем проекте xamarin forms ios. Теперь я могу получать уведомления на мои айфоны, которые отправляются от почтальона. Но при нажатии на уведомление, как я могу прочитать данные моей модели из уведомления и загрузить PCL App.xaml.cs?
При нажатии на уведомление на устройстве ios мне нужно открыть страницу контента (страницу со списком сообщений) в моем проекте PCL. Я реализовал это в своем проекте PCL App.xaml.cs. Для этого мне нужно загрузить App.xaml.cs из AppDelegate.cs с данными модели, полученными из уведомления.
Следующим способом я загружаю App.xaml.cs с Android MainActivity
LoadApplication(new App(notificationdata));
В ios DidReceiveRemoteNotification вызывается при получении уведомления для фонового и переднего режимов, но не вызывается при нажатии на уведомление.
Мое уведомление: webContentList - это данные моей модели.

webContentList - это данные моей модели, эти данные мне нужны при загрузке файла App.xaml.cs. Как я могу проанализировать эти данные из DidReceiveRemoteNotification userInfo и загрузить App.xaml.cs?
