content = new UNMutableNotificationContent();
content.Title = "Notification Title";
content.Subtitle = "Notification Subtitle";
content.Body = "This is the message body of the notification.";
content.Badge = 1;
content.CategoryIdentifier = "message";
var trigger = UNTimeIntervalNotificationTrigger.CreateTrigger(60, true);
var requestID = "sampleRequest";
var request = UNNotificationRequest.FromIdentifier(requestID, content, trigger);
UNUserNotificationCenter.Current.AddNotificationRequest(request, (err) =>
{
if (err != null)
{
// Do something with error...
}
});

Here is my code for generating a local notification on iOS
var alertsAllowed = false;
UNUserNotificationCenter.Current.GetNotificationSettings((settings) =>
{
alertsAllowed = (settings.AlertSetting == UNNotificationSetting.Enabled);
});
if (alertsAllowed)
{
var content = new UNMutableNotificationContent();
content.Title = "Incident Recorder";
content.Subtitle = "Not Synchronised";
content.Body = "There are one or more new incidents that have not been synchronised to the server.";
var trigger = UNTimeIntervalNotificationTrigger.CreateTrigger(5, false);
var requestID = "sampleRequest";
var request = UNNotificationRequest.FromIdentifier(requestID, content, trigger);
UNUserNotificationCenter.Current.AddNotificationRequest(request, (err) =>
{
if (err != null)
{
Console.WriteLine(err.LocalizedFailureReason);
}
});
}
The first parameter in CreateTrigger is how long before the notification is generated. I notice you have 60 in yours. Also bear in mind a notification will not appear if your app is foregrounded.
