Edit features (connected)

Description

This sample demonstrates how you can use popups to edit features in a feature layer.

Browse feature: Click on a feature to display the popup. The popup may contain information about a number of features depending on the density of features at the clicked location. It lists the attributes and attachments for each feature. You can enable the editing mode by clicking on the Edit button. In this mode you can edit attribute values, change geometry, add or view or delete attachments or delete the feature. To exit the editing mode you can either click on Cancel, which would ignore all the changes, or click on Finish, which would save all the changes you made during the edit session.

Add feature: Click on the Add feature to initiate adding a feature. You would be shown a list of feature templates, already available. Picking one would open the popup for the new feature in the editing mode. You can use the geometry button the on bottom left to specify the location for the new feature. Once you are finished updating the attributes or attachments you can click on the Finish button to save the feature or on Cancel button to discard.

How it works

The sample uses the AGSPopupsContainerViewController to display the container view controller and AGSPopup objects to populate the container. The map view controller conforms to the AGSPopupsContainerDelegate for events like interaction or editing or deletion. For feature templates or feature types it uses the featureTemplates and featureTypes property on the AGSServiceFeatureTable associated with the feature layer. To create a feature from selected template it uses the createFeatureWithTemplate:, addFeature:completion:, applyEditsWithCompletion: methods, again on the service feature table.
