Question

我只是想在我的多平台应用程序中找到一个非常简单的POC，在跨平台的xamarin解决方案中找到ibeacons。我已经掌握了Android方面的事情，但只是遇到iOS方面的问题。

我在AppDelegate类中得到了以下被黑客攻击的代码（这只是为了第一次使用它，我意识到这不应该存在于其中）：

[Register("AppDelegate")]
public partial class AppDelegate : UIApplicationDelegate
{
    UIWindow window;

    static readonly string uuid = "B9407F30-F5F8-466E-AFF9-25556B57FE6D";
    static readonly string monkeyId = "Monkey";

    CBPeripheralManager peripheralMgr;
    BTPeripheralDelegate peripheralDelegate;
    CLLocationManager locationMgr;

    public override bool FinishedLaunching(UIApplication app, NSDictionary options)
    {
        window = new UIWindow(UIScreen.MainScreen.Bounds);

        myAppManagerApp.Init(typeof(myAppManagerApp).Assembly);
        Forms.Init();
       // FormsMaps.Init();            

        UINavigationBar.Appearance.BackgroundColor = UIColor.FromRGBA(0, 0, 0, 0);
        UINavigationBar.Appearance.TintColor = UIColor.Blue;          
        UINavigationBar.Appearance.SetTitleTextAttributes(new UITextAttributes()
        {
            TextColor = UIColor.White
        });

        window.RootViewController = BuildView();
        window.MakeKeyAndVisible();

        var monkeyUUID = new NSUuid(uuid);
        var beaconRegion = new CLBeaconRegion(monkeyUUID, monkeyId);
        //power - the received signal strength indicator (RSSI) value (measured in decibels) of the beacon from one meter away
        var power = new NSNumber(-59);
        NSMutableDictionary peripheralData = beaconRegion.GetPeripheralData(power);
        peripheralDelegate = new BTPeripheralDelegate();
        peripheralMgr = new CBPeripheralManager(peripheralDelegate, DispatchQueue.DefaultGlobalQueue);
        peripheralMgr.StartAdvertising(peripheralData);

        locationMgr = new CLLocationManager();
        locationMgr.RegionEntered += (object sender, CLRegionEventArgs e) =>
        {
            if (e.Region.Identifier == monkeyId)
            {
                var notification = new UILocalNotification() { AlertBody = "There's a monkey hiding nearby!" };
                UIApplication.SharedApplication.PresentLocationNotificationNow(notification);
            }
        };

        locationMgr.DidStartMonitoringForRegion += locationMgr_DidStartMonitoringForRegion;
        locationMgr.MonitoringFailed += locationMgr_MonitoringFailed;

        locationMgr.StartMonitoring(beaconRegion);
        locationMgr.StartRangingBeacons(beaconRegion);

        locationMgr.DidRangeBeacons +=locationMgr_DidRangeBeacons;

        return true;
    }

    private void locationMgr_DidRangeBeacons(object sender, CLRegionBeaconsRangedEventArgs e)
    {
            throw new NotImplementedException();
    }

    private void locationMgr_MonitoringFailed(object sender, CLRegionErrorEventArgs e)
    {
        throw new NotImplementedException();
    }

    private void locationMgr_DidStartMonitoringForRegion(object sender, CLRegionEventArgs e)
    {
        int i = 0;
        //throw new NotImplementedException();
    }

    static UIViewController BuildView()
    {
        var root = new pgeRoot();
        var controller = root.CreateViewController();
        return controller;
    }

我已经将大部分代码从查找猴子样本中删除了。无论哪种方式，DidRangeBeacons或RegionEntered事件都不会触发。我正在使用estimote iBeacons，所以我不知道这是否有所作为？

关于我在这里缺少什么的任何想法？是否有需要放入plist的权限或设置？

在iOS 8中，您需要明确要求使用位置服务的权限 - 它是CLLocationManager＆＃39; RequestAlwaysAuthorization（用于监控）和RequestWhenInUseAuthorization（用于测距）方法。您还需要在iOS应用的Info.plist文件中输入相应的（NSLocationAlwaysUsageDescription和NSLocationWhenInUseUsageDescription）条目，但我并不完全确定如何在Xamarin中执行此操作。

Xamarin Estimote没有找到iOS的信标
