ISCIHitTestable

@protocol ISCIHitTestable <NSObject>

Defines the base interface for a type which can be hit-tested.

  • Translates the point relative to the other ISCIHitTestable element.

    Declaration

    Objective-C

    - (CGPoint)translatePoint:(CGPoint)point
                  hitTestable:(nonnull id<ISCIHitTestable>)hitTestable;

    Swift

    func translate(_ point: CGPoint, hitTestable: ISCIHitTestable) -> CGPoint

    Parameters

    point

    The point which should be transformed.

    hitTestable

    The other ISCIHitTestable to use when transforming the point.

    Return Value

    The translated CGPoint.

  • Checks if the point is within the bound of the current ISCIHitTestable element.

    Declaration

    Objective-C

    - (BOOL)isPointWithinBounds:(CGPoint)point;

    Swift

    func isPoint(withinBounds point: CGPoint) -> Bool

    Parameters

    point

    The point to test.

    Return Value

    YES - if the point is within bounds.

  • Checks if the point specified relative to another ISCIHitTestable element is within the bound of the current ISCIHitTestable element.

    Declaration

    Objective-C

    - (BOOL)isPointWithinBounds:(CGPoint)point
                    hitTestable:(nonnull id<ISCIHitTestable>)hitTestable;

    Swift

    func isPoint(withinBounds point: CGPoint, hitTestable: ISCIHitTestable) -> Bool

    Parameters

    point

    The point to test.

    hitTestable

    The other ISCIHitTestable to use when checking the point.

    Return Value

    YES if the point is within bounds.

  • Gets the bounds of the current ISCIHitTestable relative to the other ISCIHitTestable element.

    Declaration

    Objective-C

    - (CGRect)getBoundsRelativeTo:(nonnull id<ISCIHitTestable>)hitTestable;

    Swift

    func getBoundsRelative(to hitTestable: ISCIHitTestable) -> CGRect

    Parameters

    hitTestable

    The other ISCIHitTestable to use when transforming the point.

    Return Value

    The translated CGRect bounds.

  • Gets the UIView instance associated with this ISCIHitTestable element.

    Declaration

    Objective-C

    @property (nonatomic, readonly, nonnull) UIView *view;

    Swift

    var view: UIView { get }
