voltmx.actionExtension Namespace

The voltmx.actionExtension Namespace provides support for the iOS Action extension, which is a kind of iOS app extension.

An Action extension helps users view or update content originating in a host app. For example, an Action extension might help users edit an image in a document that they're viewing in a document editor. For more information about what Action extensions are and what you can use them for, please see the Apple developer documentation.

You add an Action extension to your app in the same way that you add any other type of iOS app extension. For more details, refer App Extension API for iOS.

Before your Action extension can be used, your app must set the callback functions that provide the Action extension with its functionality. It does this by invoking the voltmx.actionExtension.setExtensionsCallbacks function.

The voltmx.actionExtension Namespace contains the following API elements.
