Identify & mapView:didClickCalloutAccessoryButtonForGraphic

JeffPapirtis

Has anyone figured out the proper way to set up a table push with attributes after performing an Identify Task?

I have been able to do this with AGSQueryTask, but would like to know how I can acheive this using the Identify Task. 

My code reads as follows:

//when a user clicks the detail disclosure button on the call out
-(void)mapView:(AGSMapView *)mapView didClickCalloutAccessoryButtonForGraphic:(AGSGraphic *)graphic {

//lazily create the view for the feature details
    FeatureDetailsController *featureDetailViewController = [[FeatureDetailsController alloc] initWithNibName:@FeaturesDetailViewController
                                                                                                      bundle:nil];
if ([identifyPicker selectedRowInComponent:0] == 0){
    //give feature info to details view and push on to stack (i.e. make it visible)
featureDetailViewController.feature = graphic;
featureDetailViewController.displayFieldName = @wellname;
    [self.navigationController pushViewController:featureDetailViewController animated:YES];
    [featureDetailViewController release];
}
}
//Creates the Graphics when an Item is selected.
- (void)identifyTask:(AGSIdentifyTask *)identifyTask operation:(NSOperation *)op didExecuteWithIdentifyResults:(NSArray *)results {

if ([identifyPicker selectedRowInComponent:0] == 0){
 
//Turn off network activity indicator
    [AGSMapView showNetworkActivityIndicator:FALSE];

    //clear previous results
    [self.graphicsLayer removeAllGraphics];
 
  wellViewInfoTemplate *wellTemplate =[[wellViewInfoTemplate alloc] init];

 
    //add new results

  AGSSymbol* symbol = [AGSSimpleMarkerSymbol simpleMarkerSymbol];
  symbol.color = [UIColor colorWithRed:0 green:0 blue:1 alpha:0.5];
  for (AGSIdentifyResult* result in results) {
   result.feature.symbol = symbol;
   result.feature.infoTemplate = wellTemplate;
   [self.graphicsLayer addGraphic:result.feature];
  }
  [self.graphicsLayer dataChanged];



featureDetailViewController.feature = graphic;
This seems to be the problem.  When it is commented out it pushes to the Tableview, but no attributes are present.  When it is not commented out as soon as I hit the graphic button the application will crash without any errors or exceptions.

So has anyone got any pointers for me, or solutions!  Any help would be greatly appreciated!

Hi,
When your app crashes on the simulator without any error messages , this means that you are over releasing an object or you are calling a function or variable on a deallocated instance.

When you are going through such a scenario , do this

1) On Xcode top bar click on Project - > Edit Active Executable
2) Now you will get a window with two textboxes , the second textbox name is "Variables to be set in the environment"
3) Click on "+" button below , now you will have to add a new field
4) Now type the name entry as NSZombieEnabled and put its value as YES , ensure this entry is ticked
5) Clean your project and build, just before crash you will the object which is getting deallocated.

if u cant follow the above instructions just search for NSZombieEnabled in google 😛

I have not worked with identity results , but i can say that your graphics object whose reference u stored may be getting released.

Do something like this
AGSSymbol* symbol = [AGSSimpleMarkerSymbol simpleMarkerSymbol];
symbol.color = [UIColor colorWithRed:0 green:0 blue:1 alpha:0.5];
for (AGSIdentifyResult* result in results) {
result.feature.symbol = symbol;
result.feature.infoTemplate = wellTemplate;
[self.graphicsLayer addGraphic:result.feature];
featureDetailViewController.feature = result.feature ; // try adding this statement in here
}
[self.graphicsLayer dataChanged];

Get back to me if u have any problems
