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.

You should create a retain property for  AGSCalloutTemplate *template.

I've added the following to my header file:


    LocationInfoTemplate *_locationInfoTemplate;

@property (nonatomic, retain) LocationInfoTemplate * locationInfoTemplate;


But it still fails.

I miss the old-skool Retain command, but i can't use it when using ARC.. 😞

Did you do following? And it still crashing?
           
self.locationInfoTemplate * template = [[LocationInfoTemplate alloc] init];
//AGSCalloutTemplate* template = [[AGSCalloutTemplate alloc] init] ;
self.template.titleTemplate = @"${Username}"; 
self.template.detailTemplate = @"${TimeStamp}"; 
            
AGSGraphic *location = [[AGSGraphic alloc] initWithGeometry: mapPoint 
                                                                 symbol: pointMarker 
                                                             attributes: [colleague mutableCopy]
                                                   infoTemplateDelegate:self.template]; //template];


Also, you're using geometry engine in following code line. I hope you are initializing it. Like, AGSGeometryEngine *_geometryEngine = [AGSGeometryEngine defaultGeometryEngine];

AGSGeometry *mapPoint = [_geometryEngine projectGeometry:wgspoint toSpatialReference:self.mapView.spatialReference];


If you are doing all above then please attach your sample project so I can have a look at it.

I'm looping through a dictionary while executing the above code.... (I'm adding a couple of graphics to the layer)

hello,

im facing the same problem after converting the project to ARC, im adding AGSGraphic to the graphics layer in a loop, when i click on the graphics point to show the callout, it gives this error

AGSCalloutTemplate respondsToSelector:]: message sent to deallocated instance 0xfd807a0


thanks for any help

Did you create a strong property for AGSCalloutTemplate?

in .h file
@property (nonatomic, strong) AGSCalloutTemplate *calloutTemplate;

in .m file
@synthesize calloutTemplate;
self.calloutTemplate=[[AGSCalloutTemplate alloc]init];

If you loop through a dictionary and create multiple AGSInfoTemplate objects, be sure to put them in a retained (strong) NSMutableArray or some other data structure. That should keep them around when the graphic is tapped.
