I have a tableView that holds an array of records that correspond with AGSGraphics which are in a mapView. The tableView and mapView are separate views. The goal here is to allow the user to tap the tableView's accessoryButton then the view changes to the mapView and a callout for the corresponding AGSGraphic shows. I can step through the code until I get to the first method in the infoTemplateDelegate. It is here that the Xcode gives the error message: "CALayer position contains NaN: [nan nan]". I am listing the code below in the order that it is stepped through. I have two graphics layers - one that holds the graphics on the map (myGraphicsLayer) and another that is used to show the callout (popupGraphicsLayer). This seems odd so perhaps this is where I have messed up. pointsTableController.m - (void)tableView:(UITableView *)tableView accessoryButtonTappedForRowWithIndexPath: (NSIndexPath *)indexPath {         GPS1AppDelegate *delegate = (GPS1AppDelegate *)[[UIApplication sharedApplication] delegate];     mapViewController = [[MapView alloc] init];     [delegate.navController pushViewController:mapViewController animated:YES];         NSUInteger matchingObjectID;     for ( NSMutableDictionary *dict1 in pointRows )     {         if ( [[dict1 valueForKey:@"dict_objectid"] isEqual: [[pointRows objectAtIndex:indexPath.row] valueForKey:@"dict_objectid"]] )         {             matchingObjectID = [[dict1 valueForKey:@"dict_objectid"] intValue];         }     }            [mapViewController selectThePoint:matchingObjectID]; } MapView.m -(void)selectThePoint:(NSUInteger)objectID {         self.popupGraphicsLayer = [AGSGraphicsLayer graphicsLayer];         [self.mapView addMapLayer:self.popupGraphicsLayer withName:@"Popup Layer"];         AGSGraphic *foundAGSGraphic;     foundAGSGraphic = [[AGSGraphic alloc] init];     for ( AGSGraphic *graphicItem in self.myGraphicsLayer.graphics )     {         if ( [[graphicItem.attributes valueForKey:@"dict_objectid"] intValue] == objectID )         {             foundAGSGraphic = graphicItem;         }     }     [self.popupGraphicsLayer addGraphic:foundAGSGraphic];         [self.popupGraphicsLayer dataChanged];         [self.mapView showCalloutAtPoint:nil forGraphic:foundAGSGraphic animated:YES]; } infoTemplateDelegate.m @implementation infoTemplateDelegate -(NSString *)titleForGraphic:(AGSGraphic *)graphic screenPoint:(CGPoint)screen mapPoint:(AGSPoint *)map {                 // when this is called from selectThePoint, Xcode returns                 // "CALayer position contains NaN:   [nan nan]" when                 //  the next line is stepped through.   return [graphic.attributes valueForKey:@"dict_point_number"]; } -(NSString *)detailForGraphic:(AGSGraphic *)graphic screenPoint:(CGPoint)screen mapPoint:(AGSPoint *)map {   return [graphic.attributes valueForKey:@"dict_comment"]; } @end Thanks for any help, Paul Lohr ...

I have a bit of code that does the following. Push an AGSGraphic into an array. Push each AGSGraphic item from the array into an AGSGraphicsLayer. I have a tableView whose cells correspond with the AGSGraphics shown on the map. After I tap the point to get the callout, I would like to tap the accessoryButton which calls the tableView with the related cell highlighted. The problem is establishing a relationship between the AGSGraphics and the UITableView cells. I am looking for a way to uniquely identify an AGSGraphic, preferably the same way array items are identified. I would think AGSGraphicsLayer holds an array of AGSGraphics. Perhaps there is a way similar to [array1 objectAtIndex:indexPath.row]; which can be used against an AGSGraphicsLayer? A statement such as this one would have to be called in mapView:didClickCalloutAccessoryButtonForGraphic (I assume). Thanks for any help, Paul Lohr ... View more

I have a problem with the way I've setup the pushing of attributes into an AGSGraphic. Here is what I am doing:     NSMutableArray *myGraphicArray = [[NSMutableArray alloc] init];         // myMarkerPointArray is an NSMutableArray of AGSPoint objects.     for ( AGSPoint *item in myMarkerPointArray )         {                        // textFileMgmt1.points contains an NSMutableArray containing three NSMutableDictionaries of attributes    for ( NSMutableDictionary *itemDictionary in textFileMgmt1.points )                                 {                 AGSGraphic *myGraphic = [[AGSGraphic alloc] initWithGeometry:item                                                                 symbol:myMarkerSymbol                                                             attributes:itemDictionary                                                   infoTemplateDelegate:self.template];     [myGraphicArray addObject:myGraphic];     [myGraphic release];                                 }                           } The result of this code is each AGSPoint gets assigned attributes three times (currently there are three objects in myMarkerPointArray). Of course the attributes should only be assigned once. Being that I have to parse two arrays at once and I'm an amateur, I don't know how to handle this. I looked for a solution in the GraphicsDemo sample but did not find anything. Thank you for any help, Paul Lohr ... View more
