ASControlNode(Subclassing) Category Reference

Declared in	ASControlNode+Subclasses.h

Overview

The subclass header ASControlNode+Subclasses defines methods to be overridden by custom nodes that subclass ASControlNode.

These methods should never be called directly by other classes.

`– sendActionsForControlEvents:withEvent:`

Sends action messages for the given control events.

- (void)sendActionsForControlEvents:(ASControlNodeEvent)controlEvents withEvent:(nullable UIEvent *)touchEvent

Parameters

`controlEvents`	A bitmask whose set flags specify the control events for which action messages are sent. See “Control Events” in ASControlNode.h for bitmask constants.
`touchEvent`	An event object encapsulating the information specific to the user event.

Discussion

ASControlNode implements this method to send all action messages associated with controlEvents. The list of targets is constructed from prior invocations of addTarget:action:forControlEvents:.
