Application crash on drowing Picture Marker Symbol

FaisalSabri

Hi ,

i'm using "did click at point" to draw my Picture Symbol on the clicked point ,

my problem is the following :

- if i clicked anywhere in the map , i add the symbol to graphic layer and draw it without any problem , but if i clicked at the same location that i have already clicked before the application will crash ,

- some times before the application crash , a small dialog with a blue arrow shows up on the picture symbol , how to disable that dialog and why the application is crashing ??

below is my code and attached image for the blue arrow :



if (Clicked == NO)
{
self.view.userInteractionEnabled = FALSE;

HUD = [[MBProgressHUD alloc] initWithView:self.view];
[self.view addSubview:HUD];

HUD.delegate = self;
HUD.labelText = @Ù?رجÙ? اÙ?اÙ?تظار;

[HUD showWhileExecuting:@selector(myTask) onTarget:self withObject:nil animated:YES];


[myGraphicsLayer removeAllGraphics];

AppDataObjectHelper* theDataObject = [self theAppDataObject];

point = mappoint;

theDataObject.XPoint = [NSString stringWithFormat:@%.11lf,mappoint.x];
theDataObject.YPoint = [NSString stringWithFormat:@%.11lf,mappoint.y];

url = [NSURL URLWithString:theDataObject.StreetLayerIndex];

IsStreetLayer = YES;

[self GetQuery:url mapPoint:point];


NSLog(@touchesBegan);

//create the callout template, used when the user displays the callout
AGSCalloutTemplate *calloutTemp = [[AGSCalloutTemplate alloc]init];

marker = [AGSPictureMarkerSymbol pictureMarkerSymbolWithImageNamed:@pushpin.png];

marker.xoffset = 5;
marker.yoffset = 5;
marker.hotspot = CGPointMake(-9, -11);

//create the graphic
AGSGraphic *graphic = [[AGSGraphic alloc] initWithGeometry:mappoint symbol:marker
attributes:nil infoTemplateDelegate:calloutTemp];

[calloutTemp release];


[myGraphicsLayer addGraphic:graphic];


self.mapView.callout.width = 250;

[graphic release];

[myGraphicsLayer dataChanged];

Clicked = YES;
}

//create the callout template, used when the user displays the callout
AGSCalloutTemplate *calloutTemp = [[AGSCalloutTemplate alloc]init];
.....
//create the graphic
AGSGraphic *graphic = [[AGSGraphic alloc] initWithGeometry:mappoint symbol:marker
attributes:nil infoTemplateDelegate:calloutTemp];

This small dialog is callout (see more information on http://help.arcgis.com/en/arcgismobile/10.0/apis/ios/1.8/concepts/index.html#/Displaying_a_Callout/00pw0000004t000000/)

If you set nil instead of calloutTemp then (I think) graphic will be without callout functionality (user cannot see any callout after touch graphic on map)

//create the graphic without callout functionality
AGSGraphic *graphic = [[AGSGraphic alloc] initWithGeometry:mappoint symbol:marker
attributes:nil infoTemplateDelegate:calloutTemp];
