CCHMapClusterController Xamarin

Mono port of the excellent CCHMapClusterController library.

Guide

Installation

Using NuGet

• A NuGet package is available in nuget.org. Simply search for CCHMapClusterController.

Downloading the DLL

• The DLL is released using Github Release. Follow this link to find the version you want.

Building the DLL

1. Open the CCHMapClusterController-Mono.sln solution.
2. Build in Release (or Debug if you want the symbolication).
3. Copy the created DLL in the CCHMapClusterController-Mono/bin/{Debug|Release} folder to your project.
4. You're done !

Sample usage

Important note

When the MKMapView request annotation views, the given IMKAnnotation may be wrapped in a MKAnnotationWrapper object (see issue #2). The workaround consists of calling the runtime to get the underlying NSObject, see below.

using CCH.MapClusterController;

namespace MyNamespace
{
	public partial class MapViewController : UIViewController
	{
		CCHMapClusterController _mapClusterController;

		public MapViewController() : base("MapViewController", null)
		{
		}

		public override void ViewDidLoad()
		{
			base.ViewDidLoad();
			
			var annotations = /* Get annotations */;
			_mapClusterController = new CCHMapClusterController(MapView);
			_mapClusterController.AddAnnotations(annotations, null);

			MapView.Delegate = new MapDelegate();
		}
	}

	internal class MapDelegate : MKMapViewDelegate
	{
		public MapDelegate() : base()
		{
		}

		public override MKAnnotationView GetViewForAnnotation(MKMapView mapView, IMKAnnotation anno)
		{
			var annotation = ObjCRuntime.Runtime.GetNSObject(anno.Handle) as CCHMapClusterAnnotation; // this is required to get the underlying annotation object

			return null;
		}
	}
}
