Displaying Callouts Directly from the Feature Service Layer

MasonMalcik

I'm a newbie at developing iOS applications with the ArcGIS SDK, and so far, my application has running smoothly, apart from the lack of callouts.  I have several dynamic feature service layers that I am using, which are displaying in the map view without any problems. However I cannot find any information on how to display the callouts directly from the feature layers displayed.  Is there a way to do this? 
Every tutorial and reference guide I see seems to suggest I have to create a separate graphics layer for the features first, then run a task in order to get information for the callout.  I would much appreciate a way of getting around this, if that is even possible.

For those of you who may be interested, I figured it out.

First, I adopted these delegates in my interface file:

<AGSMapViewLayerDelegate> <AGSMapViewCalloutDelegate> < AGSMapViewTouchDelegate>

Then, I set the delegates, added the Feature Layer, created a template for the title and detail text in the callout, and assigned the template to the feature layer

// Set the Layer Delegate self.mapView.layerDelegate = self;      // Set the Callout Delegate self.mapView.calloutDelegate = self;      // Set the Touch Delegate self.mapView.touchDelegate = self;   //-----------------Create and Add Feature Layer-------------------------     NSURL* myUrl = [NSURL URLWithString: @<place feature service URL here>];       AGSFeatureLayer* myLayer = [AGSFeatureLayer featureServiceLayerWithURL: myUrl mode: AGSFeatureLayerModeOnDemand];          // Add My Dynamic Feature Layer to Map View     [self.mapView addMapLayer:myLayer withName:@My Layer];              // Create Info Template Delegate for My Dynamic Feature Layer     AGSCalloutTemplate* myTemplate = [[AGSCalloutTemplate alloc] init] ;     myTemplate.titleTemplate = @${Field Value for Title Text};       myTemplate.detailTemplate = @${Field Value for Detail Text};            // Assign Template to My Dynamic Feature Layer     myLayer.infoTemplateDelegate = myTemplate;

I hope this helps anyone having a similar issue
