制作本地警报通知

Question

我正在使用Xamarin和iOS,但是在通知方面我遇到了很多麻烦.我可以创建一个发送到通知中心的本地推送通知,但没有声音或指示通知实际到达.如何使通知成为警报通知,以便在进入通知中心之前显示在屏幕上？

这是我正在生成通知的代码:

//create notification
var notification = new UILocalNotification ();
notification.AlertAction = "Open App";
notification.AlertTitle = "App";
notification.AlertBody = "There has been activity in the app";
notification.SoundName = UILocalNotification.DefaultSoundName;

//display notification
UIApplication.SharedApplication.ScheduleLocalNotification (notification);

编辑:问题不仅仅是声音,而是没有收到警报的反馈,它只是静默地出现在通知中心.我也要求使用此代码的权限:

var settings = UIUserNotificationSettings.GetSettingsForTypes(
                UIUserNotificationType.Alert
                | UIUserNotificationType.Badge
                | UIUserNotificationType.Sound,
                new NSSet());

            UIApplication.SharedApplication.RegisterUserNotificationSettings(settings);
            UIApplication.SharedApplication.RegisterForRemoteNotifications();

使用[notification setSoundName:UILocalNotificationDefaultSoundName]; 它会工作正常.
