public interface UIGestureRecognizerDelegate

UIGestureRecognizerDelegate interface is the delegate responsible for the communication between UIGestureRecognizer concrete objects and related objects.

Method Summary

Modifier and Type	Method and Description
default boolean	shouldBegin(UIGestureRecognizer recognizer) Returns a Boolean (default true) that indicates whether the beginning of touch interpretation by the gesture recognizer is permitted.
default boolean	shouldReceiveTouch(UIGestureRecognizer recognizer, UITouch touch) Returns a Boolean (default true) that indicates whether the gesture recognizer is permitted to receive an object that represents a touch.
default boolean	shouldRecognizeSimultaneouslyWithGestureRecognizer(UIGestureRecognizer recognizer, UIGestureRecognizer otherGestureRecognizer) Returns a Boolean (default true) that indicates whether the concurrent recognition of two gestures is permitted.

Method Detail

shouldBegin

default boolean shouldBegin(UIGestureRecognizer recognizer)

Returns a Boolean (default true) that indicates whether the beginning of touch interpretation by the gesture recognizer is permitted.

Parameters:

recognizer - The gesture recognizer that corresponds to this delegate.

Returns:

Boolean (default true) that defines whether the beginning of touch interpretation is permitted.

shouldRecognizeSimultaneouslyWithGestureRecognizer

default boolean shouldRecognizeSimultaneouslyWithGestureRecognizer(UIGestureRecognizer recognizer,
                                                                   UIGestureRecognizer otherGestureRecognizer)

Returns a Boolean (default true) that indicates whether the concurrent recognition of two gestures is permitted.

Parameters:

recognizer - The gesture recognizer that corresponds to this delegate.

otherGestureRecognizer - The other gesture recognizer.

Returns:

Boolean (default true) that indicates whether the concurrent recognition of two gestures is permitted.

shouldReceiveTouch

default boolean shouldReceiveTouch(UIGestureRecognizer recognizer,
                                   UITouch touch)

Returns a Boolean (default true) that indicates whether the gesture recognizer is permitted to receive an object that represents a touch.

Parameters:

recognizer - The gesture recognizer that asks for permission.

touch - The touch object that is to be received.

Returns:

Boolean (default true) that indicates whether the gesture recognizer is permitted to receive an object that represents a touch.
