Hi all, I'm adding some graphics manually to the map, with the following code:         double lat = [(NSNumber *) [colleague objectForKey: @"Latitude"] doubleValue];         double lon = [(NSNumber *) [colleague objectForKey: @"Longitude"] doubleValue];                 if ( !(lat == 0.00 && lon == 0.00))         {             AGSSimpleMarkerSymbol *pointMarker = [AGSSimpleMarkerSymbol simpleMarkerSymbolWithColor:[UIColor orangeColor]];             pointMarker.size = 15; //[(NSNumber *) [colleague objectForKey: @"Precision"] intValue];             pointMarker.style = AGSSimpleMarkerSymbolStyleCircle;                            AGSPoint *wgspoint = [AGSPoint pointWithX:lon y:lat spatialReference:[AGSSpatialReference spatialReferenceWithWKID:4326]];             AGSGeometry *mapPoint = [_geometryEngine projectGeometry:wgspoint toSpatialReference:self.mapView.spatialReference];             //            LocationInfoTemplate * template = [[LocationInfoTemplate alloc] init];             AGSCalloutTemplate* template = [[AGSCalloutTemplate alloc] init] ;             template.titleTemplate = @"${Username}";             template.detailTemplate = @"${TimeStamp}";                         AGSGraphic *location = [[AGSGraphic alloc] initWithGeometry: mapPoint                                                                  symbol: pointMarker                                                              attributes: [colleague mutableCopy]                                                    infoTemplateDelegate: template]; //template];             [_trackLayer addGraphic:location];             //template = Nil;         } I've got the following issue. When the user taps on the graphic, the callout is supposed to be shown. But the application crashes in some SDK assembly, to be specific: 0x0011bed8  <+0052>  tst.w r0, #255 ; 0xff in the [AGSMapView setupCalloutUiForGraphic:mapPoint] I've tried to use my own TemplateClass (LocationInfoTemplate) and the AGSCalloutTemplate class, both had the same result. To debug this, i've added the following function: - (BOOL)mapView:(AGSMapView *)mapView shouldShowCalloutForGraphic:(AGSGraphic *)graphic {     NSLog(@"Click");         return true; } Just to see what's in the Graphic object. And i was surprised: First run: _infoTemplateDelegate UIImage * 0xde9ad50 Second run: _infoTemplateDelegate __NSCFNumber * 0xde9acd0 I think i can say that the infoTemplate is NOT retained! What's the problem here? I'm using the 2.1 SDK, i'm using the latest Xcode (With ARC) and the latest iOS.... --Edit-- Updated tot 2.2.1 SDK, same behavior. ... View more

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! ... View more

Hi, We were using the legend example from the website (http://www.arcgis.com/home/item.html?id=901ca5cbcc6e4fe9bee960136c5971ba) This worked like a charm, but when we enabled the authentication on the mapserver (HTTP authentication), it stopped working. Why? In the statement AGSMapServiceInfo* msi = ((AGSDynamicMapServiceLayer*)layer).mapServiceInfo; is the MapServiceInfo allocated, but there are no credentials available! These are not copied from the layer itself, nor is done when the DynamicMapServiceLayer from the mapview is used to retrieve the MapServiceInfo. Is this wanted? Because it is NOT possible to set the credentials, without recreating the whole object... The quick and dirty fix i've used now is: AGSMapServiceInfo* msi = [[AGSMapServiceInfo alloc] initWithURL:self.mapView.dynamicLayer.URL credential:self.mapView.dynamicLayer.credential error:&error]; This works, because there is only one dynamic layer, and only one layer (the dynamic layer) which uses the legend. It's still work in progress, but this is the code as used:         NSError* error = nil;         AGSMapServiceInfo* msi;         if (((AGSDynamicMapServiceLayer*)layer).credential.authType == AGSAuthenticationTypeNone){             msi = ((AGSDynamicMapServiceLayer*)layer).mapServiceInfo;         } else {             msi = [[[AGSMapServiceInfo alloc] initWithURL:self.mapView.dynamicLayer.URL credential:self.mapView.dynamicLayer.credential error:&error] autorelease];         }         if (error)             NSLog(@"Error encountered while fetching legend : %@",error);                 if(msi.version>=10.01){    msi.delegate = self;    [msi retrieveLegendInfo];   }else {    NSLog(@"Skipping layer [%@]. ArcGIS Service must be version 10 SP1 or above",msi.URL );   } But, it didn't work in the beginning as expected. The application gave JSON paring errors, which didn't make sense. After a lot of research, we've found the reason: There was an "#" in the password. The legend is retrieved through http://user:password@url/MapServer/layers?f=json Because of the # the application couldn't find the used mapserver. I guess the same is applicable for the "/" or "\", and maybe even "&" The strange part is: With the same authentication, the mapserver itself (The map data) can be loaded... I guess this last one is a bug... It's rather dirty anyway to put the credentials in an url.. Anyway, i really want to know if my findings are correct, and if it's a bug, or something else. Many Thanks ... View more

Hi, I'm using an identifylayer, with the controller. The identify itself works, the object is highlighted with a color, but... I have to tap the object twice before the callout is shown. So, summarized: First tap: Object is selected (Highlighted) Second tap: Callout is shown I want to skip the second step, but i have no idea how. I looked into the class reference, but... couldn't find anything... The code I use: - (void)mapView:(AGSMapView *)mapView didClickAtPoint:(CGPoint)screen mapPoint:(AGSPoint *)mappoint graphics:(NSDictionary *)graphics { self.identifyParams.tolerance = 7; self.identifyParams.geometry = mappoint; self.identifyParams.size = mapViewController.mapView.bounds.size; self.identifyParams.mapEnvelope = mapViewController.mapView.envelope; self.identifyParams.returnGeometry = YES; self.identifyParams.layerOption = AGSIdentifyParametersLayerOptionAll; self.identifyParams.spatialReference = mapViewController.mapView.spatialReference;         //execute the task [self.identifyTask executeWithParameters:self.identifyParams]; } //results are returned - (void)identifyTask:(AGSIdentifyTask *)identifyTask operation:(NSOperation *)op didExecuteWithIdentifyResults:(NSArray *)results {     //clear previous results     [mapViewController.identifyLayer removeAllGraphics];     _identifyInfoTemplate = [[IdentifyInfoTemplate alloc] init];         for (AGSIdentifyResult* result in results) {         result.feature.symbol = [self determineAndReturnSymbol:AGSGeometryTypeForGeometry(result.feature.geometry)];         result.feature.infoTemplateDelegate = _identifyInfoTemplate;                 [mapViewController.identifyLayer addGraphic:result.feature];     }         //call dataChanged on the graphics layer to redraw the graphics     [mapViewController.identifyLayer dataChanged];         } ...

Hi, I'm using a dynamiclayer with a bunch of sublayers. When i change the visibillity of the sublayers (through the self.dynamicLayer.visibleLayers variable) the mapview (and thereby the dynamiclayer) doesnt change. The selected or deselected objects arent (dis)appearing, not even when the dynamiclayer datachanged method is called. Only when the map is moved the data changed (due reload of the data)... Is this wanted behaviour? It's kinda annoying that it doesnt change on the datachanged call... For now i implemented a work-around:     [self.mapView zoomToEnvelope:self.mapView.envelope animated:true]; Many thanks. ... View more
