UIGestureRecognizer(FWUIKit)

@interface UIGestureRecognizer (FWUIKit)

gestureRecognizerShouldBegin：是否继续进行手势识别，默认YES shouldRecognizeSimultaneouslyWithGestureRecognizer: 是否支持多手势触发。默认NO shouldRequireFailureOfGestureRecognizer：是否otherGestureRecognizer触发失败时，才开始触发gestureRecognizer。返回YES，第一个手势失败 shouldBeRequiredToFailByGestureRecognizer：在otherGestureRecognizer识别其手势之前，是否gestureRecognizer必须触发失败。返回YES，第二个手势失败

  • 获取手势直接作用的view，不同于view，此处是view的subview

    Declaration

    Objective-C

    @property (nonatomic, weak, readonly, nullable) UIView *fw_targetView;

  • 是否正在拖动中：Began || Changed

    Declaration

    Objective-C

    @property (nonatomic, readonly) BOOL fw_isTracking;

  • 是否是激活状态: isEnabled && (Began || Changed)

    Declaration

    Objective-C

    @property (nonatomic, readonly) BOOL fw_isActive;

  • 判断手势是否正作用于指定视图

    Declaration

    Objective-C

    - (BOOL)fw_hitTestWithView:(nullable UIView *)view;
