来自本地通知的iOS打开页面 [英] iOS open page from local notification

问题描述

我目前使用UNUserNotificationCenter从OS10中的指定时间触发本地通知. 我试图弄清楚当用户点击本地通知时如何在我的应用程序中打开特定页面.

I currently have a local notification firing from a specified time in OS10 using the UNUserNotificationCenter. I'm trying to figure out how to open a specific page in my app when the user taps on the local notification.

任何人如何做到这一点，我对于使用C#进行iOS编程确实是新手，而且我敢肯定，这样做并不是一件罕见的事情.

Anyone how to do this I'm really new to programming for iOS in C# and I'm sure its not that uncommon of a thing to do.

推荐答案

    UNDelegate _delegate;

    public override UIWindow Window
    {
        get;
        set;
    }

    public override bool FinishedLaunching(UIApplication application, NSDictionary launchOptions)
    {

        UNUserNotificationCenter center = UNUserNotificationCenter.Current;
        _delegate = new UNDelegate();
        center.Delegate = _delegate;
        center.RequestAuthorization(UNAuthorizationOptions.Alert, (bool a, NSError error) => { });
        center.GetNotificationSettings((UNNotificationSettings setting) => {});
        registerNotification();
        return true; 
    }

    public void registerNotification()
    {

        UNMutableNotificationContent content = new UNMutableNotificationContent();
        content.Body = "body";
        content.Title = "title";
        content.Sound = UNNotificationSound.Default;

        NSDateComponents components = new NSDateComponents();
        components.Weekday = 2;
        components.Hour = 8;
        UNCalendarNotificationTrigger trigger = UNCalendarNotificationTrigger.CreateTrigger(components, true);

        UNNotificationRequest request = UNNotificationRequest.FromIdentifier("ABC", content, trigger);

        UNUserNotificationCenter.Current.AddNotificationRequest(request, (NSError error) => {
            
        });
    }


    public class UNDelegate : UNUserNotificationCenterDelegate
    {
        public override void WillPresentNotification(UNUserNotificationCenter center, UNNotification notification, Action<UNNotificationPresentationOptions> completionHandler)
        {
            completionHandler(UNNotificationPresentationOptions.Sound | UNNotificationPresentationOptions.Alert);
        }

        public override void DidReceiveNotificationResponse(UNUserNotificationCenter center, UNNotificationResponse response,  Action completionHandler)
        {
            AppDelegate app = (AppDelegate)UIApplication.SharedApplication.Delegate;
            app.Window.RootViewController.PresentViewController(new ViewController1(), true, null);
        }
    }
