GLMapViewState

Objective-C


@interface GLMapViewState : NSObject

Swift

class GLMapViewState : NSObject

GLMapViewState holds the state of a mapView (like map position, locale settings, map style).

-init
Unavailable

GLMapViewState is returned by [GLMapView state]

Default -init is disabled.
Declaration
Objective-C

- (instancetype _Nonnull)init;

Methods

-updateDrawAttributesOfVectorObject:
Updates draw attributes of vector object with the style of mapView.
Declaration
Objective-C

- (BOOL)updateDrawAttributesOfVectorObject:(nonnull GLMapVectorObject *)object;
Swift

func updateDrawAttributes(of object: GLMapVectorObject) -> Bool
Return Value

YES if object is visible.


                    
                    
                    -findNearestPoint:nearTrack:maxDistance:

Finds the nearest point of track, to a given point. Useful to find the nearest point of a track when the user taps.

Declaration

Objective-C

- (BOOL)findNearestPoint:(GLMapPoint *_Nonnull)point
               nearTrack:(GLMapTrackData *_Nonnull)trackData
             maxDistance:(CGFloat)distance;

Swift

func findNearestPoint(_ point: UnsafeMutablePointer<GLMapPoint>, nearTrack trackData: GLMapTrackData, maxDistance distance: CGFloat) -> Bool

Parameters

`point`	Point on map. If point was found, this value will be set to the nearest point.
`distance`	Max distance from the track allowed.

Return Value

YES if point found, otherwise NO.

                    -mapObjectNearPoint:maxDistance:

Returns an object near a certain point on the map.

Declaration

Objective-C

- (GLMapVectorObject *_Nullable)mapObjectNearPoint:(GLMapPoint)point
                                       maxDistance:(double)maxDistance;

Swift

func mapObjectNearPoint(_ point: GLMapPoint, maxDistance: Double) -> GLMapVectorObject?

Parameters

`point`	Point on the map.
`maxDistance`	Maximum distance in points.

Return Value

Vector object on the map.


                    
                    
                    -relationsNearPoint:maxDistance:withFilters:

Searches for relations near a point on the map.

Declaration

Objective-C

- (NSArray<GLMapRelation *> *_Nullable)
    relationsNearPoint:(GLMapPoint)point
           maxDistance:(double)maxDistance
           withFilters:(NSArray<GLSearchFilter *> *_Nullable)filters;

Swift

func relationsNearPoint(_ point: GLMapPoint, maxDistance: Double, with filters: [GLSearchFilter]?) -> [GLMapRelation]?

Parameters

`point`	Point on the map.
`maxDistance`	Maximum distance in points.
`filters`	Filters for relations.

Return Value

Relations near the point.
