Adding graphics to AGSWebMap

[s26761]

Hello

I've created an AGSWebMap and displayed it in an AGSMapView. However, I've problems now to add AGSGrpahic objects to the map view. No problem if I were to use AGSTiledMapServiceLayer instead of AGSWebMap. Is this the expected behaviour with using AGSWebMap ?

Thanks.

What all layers are available in the AGSWebMap?

Hello

Got it now. Need to set up (i.e. add AGSGraphicsLayer and other stuff) in didOpenWebMap as follows:

- (void)didOpenWebMapAGSWebMap *)webMap intoMapViewAGSMapView *)mapView
{
// Once all the layers in web map are loaded
// Add AGSGraphicslayer on top
NSLog(@"didOpenWebMap");

[self setUpAfterOpenWebMap];
}

- (void)webMapDidLoadAGSWebMap *)webMap
{
NSLog(@"webMapDidLoad");

for (AGSWebMapLayerInfo *li in webMap.operationalLayers)
{
NSLog(@"title %@; layerId %@; layerType %@; mode %d; layers count %d", li.title, li.layerId, li.layerType, li.mode, [li.layers count]);
AGSPopupInfo *pi = li.popupInfo;
NSLog(@"title %@; description %@; allowEdit %@", pi.title, pi.description, pi.allowEdit);
for (AGSPopupFieldInfo *fi in pi.fieldInfos)
{
NSLog(@"fieldName %@", fi.fieldName);
}
}
}

Also, I've tried the following:

1. Set up web map with id = c14cef13d247471da5c0262db843c09e (my own web map)
Added a shapefile (SP_BDY_polyline) and configured pop-up
However, webMapDidLoad does not show AGSPopupInfo and AGSPopupFieldInfo as configured

2. For web map with id = b31153c71c6c429a8b24c1751a50d3ad (from Feature Editing sample)
webMapDidLoad shows AGSPopupInfo and AGSPopupFieldInfo as configured

Questions:

1. Any way for web map to treat my shapefile as a Feature Layer?

2. Is it necessary for web map to be based on a Feature Layer from a Feature Server for AGSPopupInfo and AGSPopupFieldInfo to be configured properly?

Thanks.

1. Any way for web map to treat my shapefile as a Feature Layer?

The shape file added to the web map is being treated as feature collection (ultimately, it is a feature layer but in this case all features resided in the web map and not in the server like a feature layer from a feature server).

2. Is it necessary for web map to be based on a Feature Layer from a Feature Server for AGSPopupInfo and AGSPopupFieldInfo to be configured properly?

No, you can configure popupInfo for the layer based on a shape file (feature collection). You are not able to find the popup info because you are looking at a wrong place. Just change your code like below and you'll see what you want to

   for (AGSWebMapLayerInfo *li in webMap.operationalLayers)
    {
        NSLog(@"title %@; layerId %@; layerType %@; mode %d; layers count %d", li.title, li.layerId, li.layerType, li.mode, [li.layers count]);
        
        if(li.featureCollection) {
           
            AGSWebMapFeatureCollection *wmfc = li.featureCollection;
            for (AGSWebMapLayerInfo *fcli in wmfc.layers)
            {
                AGSPopupInfo *pi = fcli.popupInfo;
                NSLog(@"title %@; description %@; allowEdit %@", pi.title, pi.description, pi.allowEdit);
                for (AGSPopupFieldInfo *fi in pi.fieldInfos)
                {
                    NSLog(@"fieldName %@", fi.fieldName); 
                }
            }
        }
    }

Hi Nimesh

Thanks for your reply. Yes, now I can see the AGSPopupInfo and AGSPopupFieldInfo details for the shapefile's featureCollection.

Next, I set up the delegate method below so that when I click on the accessory button for the graphic, I can see the fieldNames and their values in the popupVC.

- (void)mapViewAGSMapView *)mapView didClickCalloutAccessoryButtonForGraphicAGSGraphic *)graphic
{
NSLog(@"didClickCalloutAccessoryButtonForGraphic");

AGSPopupInfo *info = [AGSPopupInfo popupInfoForGraphic:graphic];
for (AGSPopupFieldInfo *fieldInfo in info.fieldInfos)
{
NSLog(@"fieldName = %@; label = %@", fieldInfo.fieldName, fieldInfo.label);
}

self.popupVC = [[AGSPopupsContainerViewController alloc] initWithWebMap:self.webmap forFeature:graphic usingNavigationControllerStack:NO];
self.popupVC.delegate = self;
}

However, I don't see the AGSPopupInfo stuff based on the graphic selected using NSLog. In that case, how do I then set the AGSPopupInfo's properties to allow editing and so on?

Thanks.

You should find the popupInfo like this,

AGSPopupInfo *popupInfo = [self.webMap popupInfoForFeatureLayer:(AGSFeatureLayer *)graphic.layer];

You can edit feature collections only on arcgis.com not on any mobile clients like iOS, android etc. Hence, editing will be FALSE by default. If you want to you can set 'popupInfo.allowEdit = TRUE;' explicitly after creating a popupInfo but you won't be able to save the edits.

Hi Nimesh

Thanks for your reply. I'm now able to edit the feature attribute values on the client side. You're right that the edits remain locally and are not updated to the web map hosted on ArcGIS.com. Is there a way to overcome this? Such as to save the web map from the client side after updating like what's done at ArcGIS.com. I've created the web map based on credentials as those to sign-in to ArcGIS.com.

Does it mean that edits can only be updated for features hosted on a Feature Server?

Thanks.

Unfortunately, there is not way to over come this. The feature collections can be edited only on arcgis.com.

Yes!

Hi Nimesh

I'm coming back to this thread with the release of Version 2.3. That is, can the limitation as discussed above be overcome with Version 2.3? Would it work if the webmap is hosted via ArcGIS on-line subscription?

Thanks.

Unfortunately, No, there is no way to overcome that limitation, not with v2.3 or ArcGIS Online subscription.
