UIGestureRecognizer

extension UIGestureRecognizer

Delegate Overrides

  • Equivalent to implementing UIGestureRecognizerDelegate’s gestureRecognizerShouldBegin(:) method

    Declaration

    Swift

    @discardableResult
public func shouldBegin(handler: @escaping () -> Bool) -> Self

    Parameters

    handler

    The closure that will be called in place of its equivalent delegate method

    Return Value

    itself so you can daisy chain the other delegate calls

  • Equivalent to implementing UIGestureRecognizerDelegate’s gestureRecognizer(:shouldRecognizeSimultaneouslyWith:) method

    Declaration

    Swift

    @discardableResult
public func shouldRecognizeSimultaneouslyWith(handler: @escaping (_ otherGestureRecognizer: UIGestureRecognizer) -> Bool) -> Self

    Parameters

    handler

    The closure that will be called in place of its equivalent delegate method

    Return Value

    itself so you can daisy chain the other delegate calls

  • Equivalent to implementing UIGestureRecognizerDelegate’s gestureRecognizer(:shouldRequireFailureOf:) method

    Declaration

    Swift

    @discardableResult
public func shouldRequireFailureOf(handler: @escaping (_ otherGestureRecognizer: UIGestureRecognizer) -> Bool) -> Self

    Parameters

    handler

    The closure that will be called in place of its equivalent delegate method

    Return Value

    itself so you can daisy chain the other delegate calls

  • Equivalent to implementing UIGestureRecognizerDelegate’s gestureRecognizer(:shouldBeRequiredToFailBy:) method

    Declaration

    Swift

    @discardableResult
public func shouldBeRequiredToFailBy(handler: @escaping (_ otherGestureRecognizer: UIGestureRecognizer) -> Bool) -> Self

    Parameters

    handler

    The closure that will be called in place of its equivalent delegate method

    Return Value

    itself so you can daisy chain the other delegate calls

  • Equivalent to implementing UIGestureRecognizerDelegate’s gestureRecognizer(:shouldReceive:) method

    Declaration

    Swift

    @discardableResult
public func shouldReceiveTouch(handler: @escaping (_ touch: UITouch) -> Bool) -> Self

    Parameters

    handler

    The closure that will be called in place of its equivalent delegate method

    Return Value

    itself so you can daisy chain the other delegate calls

  • Equivalent to implementing UIGestureRecognizerDelegate’s gestureRecognizer(:shouldReceive:) method

    Declaration

    Swift

    @discardableResult
public func shouldReceivePress(handler: @escaping (_ press: UIPress) -> Bool) -> Self

    Parameters

    handler

    The closure that will be called in place of its equivalent delegate method

    Return Value

    itself so you can daisy chain the other delegate calls

Reset

  • Clears any delegate closures that were assigned to this UIGestureRecognizer. This cleans up memory as well as sets the delegate property to nil. This is typically only used for explicit cleanup. You are not required to call this method.

    Declaration

    Swift

    @objc
public func clearClosureDelegates()
