public interface NSExtensionRequestHandling

The basic NSExtensionRequestHandling protocol defines a lifecycle hook into the extension. Non view-controller-based services might keep track of the current request using this method. Implemented by the principal object of the extension.

Method Summary

Modifier and Type	Method and Description
void	beginRequestWithExtensionContext(NSExtensionContext context) Tells the extension to prepare its interface for the requesting context, and request related data items.

Method Detail

beginRequestWithExtensionContext

void beginRequestWithExtensionContext(NSExtensionContext context)

Tells the extension to prepare its interface for the requesting context, and request related data items. At this point [(NS|UI)ViewController extensionContext] returns a non-nil value. This message is delivered after initialization, but before the conforming object will be asked to "do something" with the context (i.e. before -[(NS|UI)ViewController loadView]). Subclasses of classes conforming to this protocol are expected to call [super beginRequestWithExtensionContext:] if this method is overridden.
