I have a map service published to ArcGIS Server 10, with a point feature class in SDE that has 2 ole db tables related in the map document. I have successfully queried these tables through the REST interface, and gotten the expected results, but once in a while the relate query stops working but I can still retrieve the features from the point feature class. I have to restart the service in order to get the related tables query working again. The server manager logs do not show anything unusual besides hitting the max record count limit, but this does not seem to correlate with the query breaking. Also, I have seen other threads regarding related records not working if there is a join on any of the tables. I have confirmed that I do not have any joins in the map doc. ... View more

I am having trouble implementing AGSRelationshipQuery, I get a successful response, but the data returned id not what I expect and I am not sure if I am setting up my query the correct way. What I am trying to do is query related records from a point feature class (through a map service) that has a relationship set up with a table. Here is code: (the names of the server and services have been changed to protect the innocent, and unfortunately, this server is not public so i can't point anybody to it) - (void)mapView:(AGSMapView *)mapView didClickCalloutAccessoryButtonForGraphic:(AGSGraphic *)graphic {     self.queryTask = [AGSQueryTask queryTaskWithURL:[NSURL URLWithString:@"http://<myServer>/arcgis/rest/services/<myFolder>/<myService>/MapServer/0"]];     self.queryTask.delegate = self;        self.relQuery = [AGSRelationshipQuery relationshipQuery];     self.relQuery.objectIds = [NSArray arrayWithObject:[graphic.attributes objectForKey:@"OBJECTID"]];     self.relQuery.outFields = [NSArray arrayWithObject :@"*"];     self.relQuery.relationshipId = 0;     [self.queryTask executeWithRelationshipQuery:self.relQuery]; { - (void) queryTask:(AGSQueryTask *)queryTask operation:(NSOperation*)op didExecuteWithRelatedFeatures:(NSDictionary *)relatedFeatures {    NSLog(@"relatedFeatures: %@", relatedFeatures); } The response I get back from the NSLog on related Features is: relatedFeatures: (     "AGSFeatureSet: display name: (null) \ngeometry type: esriGeometryPoint \nnum features: 1 \nspatial reference: (null)" ) I have confirmed the parameters in my query are valid using the rest/services web page, and there I get a json object that has the data I expect. But I am not sure what to make of the response I am getting through the iOS API. I have also tested the a regular http request using the direct URL for the REST query, and I do get back the proper response,     NSString *relatedQueryString = @"http://<myServer>/ArcGIS/rest/services/<myFolder>/<myService>/MapServer/0/queryRelatedRecords?objectIds=1&relationshipId=0&definitionExpression=&returnGeometry=false&maxAllowableOffset=&outSR=&outFields=*&f=pjson";     NSError *theError = nil;     NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:relatedQueryString]];     NSURLResponse *theResponse = [[NSURLResponse alloc] init];     NSData *data = [NSURLConnection sendSynchronousRequest:request returningResponse:&theResponse error:&theError];     NSString *string = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];     NSDictionary *jsonDict = [string AGSJSONValue]; so I am figuring I am just not setting up the related request correctly.

I know you can't set the spatial reference directly for the mapView, but is there something out there that let's me instantiate a mapView with a certain spatial reference and extents with loading a layer first? I am trying to develop an app that can function entirely offline if need be, but so far the only way i can get that to work is by using the cached map way, as illustrated in the CustomTileOverlay sample app. Unfortunately, I don't intend to load my basemaps this way, so i would have to just have dummy tile in order to get the map view to load properly. I have tried loading layers using the decodeFromJSON method and a local file, but it doesn't seem to work unless i also have a local cache as well. ... View more

I am trying to label a polygon graphics layer. I am able to either symbolize the graphic or the label through the renderer, but I can't figure out how to do both at the same time. I see that the AGSFeatureLayer has a labeling functionality, but I am using an AGSGraphicsLayer because I am loading data locally. ... View more

I am trying to get a notification message for when the map has zoomed, to then fire off another method to do something. I read in the API docs that there is a notification sent out from AGSMapView for "MapDidEndZooming": "The map component broadcasts four notifications - MapViewDidLoad, MapTimeExtentChanged, MapDidEndPanning and MapDidEndZooming. Observers interested in these notifications can register for them using the default NSNotificationCenter." I have tried this in my viewController implementation: self.mapView.layerDelegate = self; [[NSNotificationCenter defaultCenter] addObserver:self   selector:@selector(didReceiveZoomMessage: ) name:MapDidEndZooming object:nil]; but I keep getting error stating the "MapDidEndZooming" is undeclared. ...

The management of annotation has always been a bit frustrating as in order to manage it, you have to go into the data frame properties dialog. I would really like to see the annotation moved into it's own layer in the table of contents, whether that could be a seperate tab in the TOC or if there could be an option to auto create a new feature layer for the annotation without having to associate the annotation with an existing feature layer. ...
