Hi all,I retrieve some data from a webserver, through JSON. This works flawless.In this data is the latitude, longitude and a name.I want to add this data to my mapview, i've added a AGSGraphicsLayer to do this.I add the graphics layer with the following code:
self.trackLayer = [AGSGraphicsLayer graphicsLayer];
[self.mapView addMapLayer:self.trackLayer withName:@"trackLayer"];
This works. As expected.When i push a button the data is received, and added to the map:
NSArray *locations = [_locationService getLocations];
for (NSDictionary* loc in locations) {
NSLog(@"%@", loc);
float lat = [[loc objectForKey:@"lat"] floatValue];
float lon = [[loc objectForKey:@"lon"] floatValue];
AGSSimpleMarkerSymbol *pointMarker = [AGSSimpleMarkerSymbol simpleMarkerSymbolWithColor:[UIColor redColor]];
pointMarker.size = 10.00;
pointMarker.style = AGSSimpleMarkerSymbolStyleCircle;
AGSPoint *point = [AGSPoint pointWithX:lat y:lon spatialReference:self.mapView.spatialReference];
AGSGraphic *location = [[AGSGraphic alloc] initWithGeometry:point symbol:pointMarker attributes:Nil infoTemplateDelegate:Nil];
NSLog(@"%@", location);
[_trackLayer addGraphic:location];
}
[_trackLayer dataChanged];
The NSLog produces the following:geometry: AGSPoint: x = 52.322800, y = 4.879720, spatial reference: [AGSSpatialReference: wkid = 102100, wkt = null], symbol: { AGSSimpleMarkerSymbol: style: esriSMSCircle, size: 10.000000, outline: <AGSSimpleLineSymbol: 0x8c0b50> }, attributes: (null)When i print the description of the geometry within the Graphics layer:AGSPoint: x = 52.317799, y = 4.879200, spatial reference: [AGSSpatialReference: wkid = 102100, wkt = null]So, the coordinates are in the point. For all the testdata. But they are still shown at 0,0! Whats wrong here? The only thing i saw was that the renderer and initialEnvelope of the GraphicsLayer is 0x0...Many thanks!
