MapItemKeyFrameTrack

public class MapItemKeyFrameTrack

extension MapItemKeyFrameTrack: NativeBase

extension MapItemKeyFrameTrack: Hashable

Stores keyframes for interpolation of a map item property using a specific easing function and interpolation mode.

The keyframe track object is used to create animations, see MapMarkerAnimation and MapPolylineAnimation.

InstantiationError
Thrown when a problem occurs while trying to create MapItemKeyFrameTrack.
Declaration
Swift

public typealias InstantiationError = InstantiationErrorCode


                    
                    
                    InstantiationErrorCode

Describes a reason for failing to create a MapItemKeyFrameTrack.

Declaration

Swift

public enum InstantiationErrorCode : UInt32, CaseIterable, Codable

extension MapItemKeyFrameTrack.InstantiationErrorCode : Error


                    
                    
                    moveTo(keyframes:easing:interpolationMode:)

Creates a map item position keyframe track. It enables animations over the geographical coordinates where the map item is positioned.

Throws

MapItemKeyFrameTrack.InstantiationError If the supplied keyframe list is empty or first keyframe duration is not 0.

Declaration

Swift

public static func moveTo(keyframes: [GeoCoordinatesKeyframe], easing: Easing, interpolationMode: KeyframeInterpolationMode) throws -> MapItemKeyFrameTrack

Parameters

`keyframes`	The list of keyframes that specify how the map item position changes over time.
`easing`	The easing to apply during keyframe interpolation.
`interpolationMode`	The type of interpolation done between keyframe values.

Return Value

MapItemKeyFrameTrack instance.


                    
                    
                    polylineProgress(keyframes:easing:interpolationMode:)

Creates a keyframe track used to animate the progress of a polyline.

Each scalar keyframe specifies the value of MapPolyline.progress at key points of the animation.

Throws

MapItemKeyFrameTrack.InstantiationError If the supplied keyframe list is empty or first keyframe duration is not 0.

Declaration

Swift

public static func polylineProgress(keyframes: [ScalarKeyframe], easing: Easing, interpolationMode: KeyframeInterpolationMode) throws -> MapItemKeyFrameTrack

Parameters

`keyframes`	The list of keyframes that specify how the polyline progress changes over time.
`easing`	The easing to apply during keyframe interpolation.
`interpolationMode`	The type of interpolation done between keyframe values.

Return Value

MapItemKeyFrameTrack instance.
