Hi, Michael - You're right, the SDK does not give you access to the GlobalID field. We originally made that field inaccessible because it is something that is managed by the underlying geodatabase model, and we didn't think it would be useful to application developers. But as you described, there valid cases where one needs it to manually establish relationships, or uniquely query features. The GlobalID field will be accessible in the next release of the SDK. _ Divesh ... View more

Unfortunately, there isn't a way to get the layer ID currently. We can look into adding it for an upcoming release. How do you plan to use it? If you used the AGSGDBSyncTask to generate the geodatabase, the task has a property called featureServiceInfo, which in turn has an array of layer infos for each layer in the service. This layer info contains both name and ID of the sub layers. In the meantime, if you already happen to have the layer ID and want to get the corresponding feature table,  you can use [AGSGDBGeodatabase featureTableForLayerID:]‌ ... View more

The feature layer has a property called graphics (that it inherits from the graphics layer). This property contains all the features that are currently being displayed on the map. Since you say your features will not be drawn on the map, the property is understandably empty. The only way to get features that are not drawn on the map is to query. ... View more

My question is what does this setting do exactly?  It shouldnt change the edit settings of the layer itself right? This setting stores some information in the webmap saying that the author has disabled editing on the layer. The iOS SDK, when opening the webmap, honors this setting and creates a feature layer which reports that it doesn't support editing (the canCreate, canUpdate, and canDelete properties on AGSFeatureLayer returns NO). Of course, the backend feature service still supports editing (it remains unmodified), but since the feature layer chooses to not expose this onwards, things like popups (which inspect the feature layer's properties) don't provide the option to edit features in that layer. If you were to not use the feature layer instance returned by the web map in  webMap:didLoadLayer: delegate method, and instead create your own feature layer pointing to the URL of the feature service directly, your layer would report that it IS capable of editing. ...

Unfortunately, the API does not provide the ability to discard local edits on a feature by feature basis. A good one for ideas.arcgis.com though ... View more

Yes, you can modify the geometry of that feature using AGSGeometryEngine cutGeometry:withCutter: ... View more

The esri elevation services are free (they don't utilize credits) but they can only be accessed through an ArcGIS Online Organization subscription. More details in this blog post - Introducing Esri’s World Elevation Services | ArcGIS Blog‌ If your apps user has an org subscription account, you can use the AGSOAuthLoginViewController class in the SDK to allow the end user to log in to their account. This class returns to you an AGSCredential object when the user successfully logs in. See OAuth Login Sample Once you have the credential,  you can use it to open web maps that contain elevation layers, or you can load the elevation layers directly and add them to the map view as AGSImageServiceLayer objects ...

Yes, it is possible, although some things might be easier if the layer was added to the map view. If you don't add it to the map, you will probably need to instantiate the feature layer in either snapshot mode, or selection mode. This doc, ArcGIS Feature layer , contains some information about the different modes.(In contrast, the OnDemand mode is better suited for when you add the layer to the map, in which case the layer will retrieve features from the service that fall within the map's view extent.) Without adding the layer to the map, the features won't display, and users won't be able to tap on a feature to begin editing. Your app will need to handle this workflow a different way or write some code to provide this experience. To edit a specific feature, you will first need to query it using [AGSFeatureLayer queryFeatures:]. Once you have a reference to the feature, you can modify its attributes/attachments/geometry, and then send the updates back to the service using [AGSFeatureLayer applyEditsWithFeaturesToAdd:toUpdate:toDelete: ] This sample (RelatedRecordEditingSample) uses this pattern to edit records (incident notes) that are related to a feature layer (incidents). The incident notes are pure tabular data and cannot be visualized on a map, hence the feature layer that is used to edit them is not added to a map. (See NotesViewController.m ) ... View more
