SCIPinchZoomModifier Class Reference


                        
                        
                        gestureRecognizer

Defines UIPinchGestureRecognizer which is used to detect pinch gestures.

Declaration

Objective-C

@property (nonatomic, weak, readonly, nullable) UIPinchGestureRecognizer *gestureRecognizer;

Swift

weak var gestureRecognizer: UIPinchGestureRecognizer? { get }


                        
                        
                        pinchZoomDelegate

Undocumented

Declaration

Objective-C

@property(nonatomic, weak) id <SCIPinchZoomModifierDelegate> _Nullable pinchZoomDelegate

Swift

weak var pinchZoomDelegate: (any SCIPinchZoomModifierDelegate)? { get set }


                        
                        
                        scaleFactor

Defines the scale factor to scale (or shrink) both axes on pinch gesture.

Declaration

Objective-C

@property (nonatomic) CGFloat scaleFactor;

Swift

var scaleFactor: CGFloat { get set }


                        
                        
                        direction

Defines the SCIDirection2D which restricts zoom interactivity to.

Declaration

Objective-C

@property (nonatomic) SCIDirection2D direction;

Swift

var direction: SCIDirection2D { get set }


                        
                        
                        isUniformZoom

Defines the value which indicates whether uniform zoom should be used by this modifier.

Note

When uniform zoom is set to YES - then modifier applies same scale factor for both x and y direction, otherwise - scale factor calculated separately for x and y direction based on information from touch events.

Declaration

Objective-C

@property (nonatomic) BOOL isUniformZoom;

Swift

var isUniformZoom: Bool { get set }
