INFO

This English reference is based on Directions SDK 1.12.12. For the latest version, see the Korean reference.

Configures a Polyline with pattern images, segmented colors, and other custom styles.

Constructor

Creates a KNMapSegmentPolyline object.

KNMapSegmentPolyline* segmentLine = [KNMapSegmentPolyline segmentPolyline];
[self->mapView addSegmentPolyline:segmentLine];

Properties

Name	Description	Type
strokeColor	Outline color	@property (nonatomic, assign, nonnull) UIColor* strokeColor;
lineWidth	Line width (default: 15, range: 1–50)	@property (nonatomic, assign) float lineWidth
strokeWidth	Outline width (default: 4, range: 0–10)	@property (nonatomic, assign) float strokeWidth
capType	Shape of both line ends	@property (nonatomic, assign) KNLineCapType capType
isVisible	Whether the line is visible (default: YES)	@property (nonatomic, assign) BOOL isVisible

Methods

addSegment:countPoints:color

Creates a line segment from multiple KATEC coordinate vertices and colors, then connects it to the last segment.

Example code

KNMapSegmentPolyline* segmentLine = [KNMapSegmentPolyline segmentPolyline];
 
FloatPoint *positions = nil; 
positions = realloc(positions, sizeof(FloatPoint)*2);
 
positions[0] = FloatPointMake(321832.0, 533175.0);
positions[1] = FloatPointMake(321832.0, 532975.0);
 
UIColor* color = [[UIColor alloc] initWithRed:(float)(rand() % 256) / 255.0 green:(float)(rand() % 256) / 255.0 blue:(float)(rand() % 256) / 255.0 alpha:1.0];
[segmentLine addSegment:positions countPoints:2 color:color];
[self->mapView addSegmentPolyline:segmentLine];
