Excellent! Thank you very much. UIGetScreenImage() worked for me too. ... View more

Hey Guys, I have followed the above example and tried moving the renderers around.  Like some of the other comments the code works great in the simulator but when I put it onto my iPad, I get a black image.  Has anyone figured this out?  I am sure I am just doing something wrong. Cheers, Jeff On the device, try sending the app to the background and bringing it back to the foreground. For some reason, it starts working after bringing the app back from the background.. I am looking forward to get an answer/comment from ArcGIS team on this issue. ... View more

I use the getImage method from bernese. I use it in this manner: //export image of mapView        UIImage *screenshot = [[UIImage alloc] initWithData:[self getImage]]; //save image to photo album UIImageWriteToSavedPhotosAlbum(screenshot,self,@selector(image:didFinishSavingWithError:contextInfo:),nil); Edit: I do not have any code similar to the DrawableProperty snippet you included. Thank you very much for your reply. I noticed that the code starts working if you send the app to the background and bring it back. It is weird but it starts working correctly after sending the app to the background and getting it back to the foreground but it does not work before doing it, it just shows blank image.. ...

Thanks a lot for this... However this only works in the simulator but the same code returns a blank screen in the device. Any idea why this might be.\ Thanks again Have you solved this problem? I am facing the same issue (not working on the device) and moving the following code did not help as suggested:     CAEAGLLayer *eaglLayer = (CAEAGLLayer *) theMap.layer;     eaglLayer.drawableProperties = @{                                      kEAGLDrawablePropertyRetainedBacking: [NSNumber numberWithBool:YES],                                      kEAGLDrawablePropertyColorFormat: kEAGLColorFormatRGBA8                                      }; I would appreciate if you could share your solution. Thanks. ... View more

Hi Divesh, Do you know any ideas or a solution for this. Can we expect a fix soon for this or do we need to use AGSSimpleMarkerSymbol instead of AGSPictureMarkerSymbol for now? Thanks, Oguzhan. ... View more

That's it! It worked.. You are the MAN! 🙂 Much appreciated, Regards. Okay, what is the spatial reference of the map (self.mapView.spatialReference)? What is the spatial reference of the geometries returned by query task? If they are different then you should set out spatial reference to self.mapView.spatialReference of the query so server return geometries in map's spatial reference. query.outSpatialReference = self.mapView.spatialReference; Regards, Nimesh ...

Thanks again for your answer. I read the documentation and I think everything I do (with your help) looks correct. However, it still do not work. I tried so many things.. To see if I can draw a line on the graphics layer, I tried the following and it worked. But it does not work with the graphics from queryTask.                 AGSMutablePolyline *polyline = [[AGSMutablePolyline alloc] initWithSpatialReference:self.mapView.spatialReference];         [polyline addPathToPolyline];         [polyline addPointToPath:myPoint1];         [polyline addPointToPath:myPoint2];         AGSGraphic *poly = [[AGSGraphic alloc] initWithGeometry:polyline                                                          symbol:[AGSSimpleLineSymbol simpleLineSymbolWithColor:[UIColor blackColor]]                                                      attributes:nil                                            infoTemplateDelegate:nil];         [self.graphicsLayer addGraphic:poly];         [poly release]; Thanks for you time, Regards. I said, "If returned graphics has polygon geometry then do this." but since geometry is polyline you should create simple line symbol. Just use below code and it will handle all type of geometry. - (void)queryTask:(AGSQueryTask *)queryTask operation:(NSOperation *)op didExecuteWithFeatureSetResult:(AGSFeatureSet *)featureSet {            [self.graphicsLayer removeAllGraphics];                 AGSSimpleFillSymbol *simpleFillSymbol = [AGSSimpleFillSymbol simpleFillSymbol]; for (AGSGraphic *graphic in featureSet.features) {                                     if ([graphic.geometry isKindOfClass:[AGSPoint class]] || [graphic.geometry isKindOfClass:[AGSMultipoint class]]) {                          graphic.symbol = [AGSSimpleMarkerSymbol simpleMarkerSymbol];                     }                     else if ([graphic.geometry isKindOfClass:[AGSPolyline class]]) {                          graphic.symbol = [AGSSimpleLineSymbol simpleLineSymbol];                     }                     else if ([graphic.geometry isKindOfClass:[AGSPolygon class]]) {                          graphic.symbol = [AGSSimpleFillSymbol simpleFillSymbol];                     }                                    graphic.visible = YES;                     [self.graphicsLayer addGraphic:graphic]; } [self.graphicsLayer dataChanged]; } Also, go through working with symbols and renderer documentation. That'll help you understand everything. Regards, Nimesh ... View more

Thanks for your reply. The geometry is esriGeometryPolyline. I tried what you recommended but it didn't work. Then I checked graphicsLayer's renderer. It is null. Even though I tried the following to set the renderer, my self.graphicsLayer.renderer is still null.     self.graphicsLayer.renderer = [[AGSSimpleRenderer simpleRendererWithSymbol:[AGSSimpleFillSymbol simpleFillSymbol]] retain]; Now my code is as follows: - (void)queryTask:(AGSQueryTask *)queryTask operation:(NSOperation *)op didExecuteWithFeatureSetResult:(AGSFeatureSet *)featureSet {     NSLog ( @"Renderer: %@", [self.graphicsLayer.renderer description]);     NSLog( @" featureSet: %@", [featureSet description]);     [self.graphicsLayer removeAllGraphics];     AGSSimpleFillSymbol *simpleFillSymbol = [AGSSimpleFillSymbol simpleFillSymbol]; for (AGSGraphic *graphic in featureSet.features) {         graphic.visible = YES;         graphic.symbol = simpleFillSymbol;   [self.graphicsLayer addGraphic:graphic];         NSLog(@" graphic: %@", [graphic description]); } [self.graphicsLayer dataChanged]; } I get the following output: Renderer: (null) featureSet: AGSFeatureSet: display name: SEGMENT_PREFIX geometry type: esriGeometryPolyline num features: 100 spatial reference: AGSSpatialReference: wkid = 4326, wkt = null graphic: geometry: AGSPolyline: [envelope: AGSEnvelope: xmin = -83.691725, ymin = 36.763704, xmax = -83.378514, ymax = 36.886530, spatial reference: [AGSSpatialReference: wkid = 4326, wkt = null]], symbol: <AGSSimpleFillSymbol: 0xacc3110>, attributes: {     "ENG_REGION" = SOUTH;     OBJECTID = 25;     "SEGMENT_PREFIX" = 0SC;     "SHAPE.LEN" = "41502.858489515296"; }, visible: 1 Any suggestions? What type of renderer is set for the graphics layer? The returned graphics from query task ash which type of geometry? If render set on the graphics layer does not support geometry returned by query task then you should set symbol on each graphic before adding them to the graphics layer and it should draw it. If returned graphics has polygon geometry then do this. - (void)queryTask:(AGSQueryTask *)queryTask operation:(NSOperation *)op didExecuteWithFeatureSetResult:(AGSFeatureSet *)featureSet {            [self.graphicsLayer removeAllGraphics];                 AGSSimpleFillSymbol *simpleFillSymbol = [AGSSimpleFillSymbol simpleFillSymbol]; for (AGSGraphic *graphic in featureSet.features) {                 graphic.visible = YES;                 graphic.symbol = simpleFillSymbol;   [self.graphicsLayer addGraphic:graphic]; } [self.graphicsLayer dataChanged]; } Hope this helps!
