clusterlayer-plugin-ios

A cluster layer extension to the ArcGIS Runtime for iOS.

The gridding code is based heavily on Leaflet.markercluster

##Usage

1. Import AGSClusterLayer.h
2. Add an AGSFeatureLayer to the AGSMapView
3. Create an AGSClusterLayer with the AGSFeatureLayer and add it to the AGSMapView

#import "AGSClusterLayer.h"

#define kGreyBasemap @"http://services.arcgisonline.com/ArcGIS/rest/services/Canvas/World_Light_Gray_Base/MapServer"
#define kGreyBasemapRef @"http://services.arcgisonline.com/ArcGIS/rest/services/Canvas/World_Light_Gray_Reference/MapServer"

- (void)viewDidLoad
{
    [super viewDidLoad];

    [self.mapView addMapLayer:[AGSTiledMapServiceLayer tiledMapServiceLayerWithURL:[NSURL URLWithString:kGreyBasemap]]];

    AGSFeatureLayer *featureLayer = [AGSFeatureLayer featureServiceLayerWithURL:[NSURL URLWithString:kFeatureLayerURL] mode:AGSFeatureLayerModeOnDemand];
    [self.mapView addMapLayer:featureLayer];
    
    self.clusterLayer = [AGSClusterLayer clusterLayerForFeatureLayer:featureLayer];
    [self.mapView addMapLayer:self.clusterLayer];

    self.clusterLayer.showClusterCoverages = self.coverageSwitch.on; // By default, coverages are not shown
}
