MapboxMap Class Reference

style
The style object supports run time styling.
Declaration
Swift

public internal(set) var style: Style { get }

Style loading


                    
                    
                    loadStyleURI(_:completion:)

Loads a style from a StyleURI, calling a completion closure when the style is fully loaded or there has been an error during load.

Declaration

Swift

public func loadStyleURI(_ styleURI: StyleURI, completion: ((Result<Style, Error>) -> Void)? = nil)

Parameters

`styleURI`	StyleURI to load
`completion`	Closure called when the style has been fully loaded. The `Result` type encapsulates the `Style` or error that occurred. See `MapLoadingError`


                    
                    
                    loadStyleJSON(_:completion:)

Loads a style from a JSON string, calling a completion closure when the style is fully loaded or there has been an error during load.

Declaration

Swift

public func loadStyleJSON(_ JSON: String, completion: ((Result<Style, Error>) -> Void)? = nil)

Parameters

`styleURI`	Style JSON string
`completion`	Closure called when the style has been fully loaded. The `Result` type encapsulates the `Style` or error that occurred. See `MapLoadingError`

Prefetching

prefetchZoomDelta
When loading a map, if prefetchZoomDelta is set to any number greater than 0, the map will first request a tile for zoom - prefetchZoomDelta in an attempt to display a full map at lower resolution as quick as possible.

It will get clamped at the tile source minimum zoom. The default delta is 4.
Declaration
Swift

public var prefetchZoomDelta: UInt8 { get set }
resourceOptions
Gets the resource options for the map.

All optional fields of the returned object are initialized with the actual values.

Note
The result of this property is different from the ResourceOptions that were provided to the map’s initializer.
Declaration
Swift

public var resourceOptions: ResourceOptions { get }


                    
                    
                    elevation(at:)

Gets elevation for the given coordinate.

Note

Elevation is only available for the visible region on the screen.

Declaration

Swift

public func elevation(at coordinate: CLLocationCoordinate2D) -> Double?

Parameters


                                  coordinate

Coordinate for which to return the elevation.

Return Value

Elevation (in meters) multiplied by current terrain exaggeration, or empty if elevation for the coordinate is not available.

Return Value
