GLMapRasterTileSource

Objective-C


@interface GLMapRasterTileSource : GLMapTileSource

Swift

class GLMapRasterTileSource : GLMapTileSource

GLMapRasterTileSource is used to setup custom raster tile source.

  • Initializes tile source. If cachePath==nil no caching will happens.

    Declaration

    Objective-C

    - (instancetype _Nullable)initWithCachePath:(NSString *_Nullable)cachePath;

    Swift

    init?(cachePath: String?)

  • Gets url of tile. Default implementation reuturns nil.

    Declaration

    Objective-C

    - (NSURL *_Nullable)urlForTilePos:(GLMapTilePos)pos;

    Swift

    func url(for pos: GLMapTilePos) -> URL?

  • Gets image data of tile. Default implementation reuturns nil.

    Declaration

    Objective-C

    - (NSData *_Nullable)imageDataForTilePos:(GLMapTilePos)pos
                                 expired:(BOOL *_Nonnull)expired;

    Swift

    func imageData(for pos: GLMapTilePos, expired: UnsafeMutablePointer<ObjCBool>) -> Data?

  • Gets image of tile. Default implementation reuturns nil.

    Declaration

    Objective-C

    - (PlatformImage *_Nullable)imageForTilePos:(GLMapTilePos)pos
                                    expired:(BOOL *_Nonnull)expired;

    Swift

    func image(for pos: GLMapTilePos, expired: UnsafeMutablePointer<ObjCBool>) -> NSImage?

  • Override this to implement custom caching. Default implementation does nothing.

    Declaration

    Objective-C

    - (void)saveTileData:(NSData *_Nonnull)data forTilePos:(GLMapTilePos)pos;

    Swift

    func saveTileData(_ data: Data, for pos: GLMapTilePos)

  • Cached tile will be refreshed if it will stay in cache more than given time.

    By default tileRefreshTimeInterval = -1. If tileRefreshTimeInterval < 0 no tile refreshing will be triggered.

    Declaration

    Objective-C

    @property int64_t tileRefreshTimeInterval;

    Swift

    var tileRefreshTimeInterval: Int64 { get set }

  • Defines valid zooms for tile source. Default is 0xFFFFFFFF.

    Declaration

    Objective-C

    @property uint32_t validZoomMask;

    Swift

    var validZoomMask: UInt32 { get set }

  • Allows to draw tiles after maximum zoom

    Declaration

    Objective-C

    @property BOOL overzoom;

    Swift

    var overzoom: Bool { get set }

  • Size of tile in points. Could be used to magnify raster tiles. Default is 256.

    Declaration

    Objective-C

    @property uint32_t tileSize;

    Swift

    var tileSize: UInt32 { get set }

  • Sets attribution text for map source. Default is @“© OpenStreetMap”

    Declaration

    Objective-C

    @property (strong) NSString *_Nullable attributionText;

    Swift

    var attributionText: String? { get set }

  • Gets size of cache file

    Declaration

    Objective-C

    @property (readonly) uint64_t cacheSize;

    Swift

    var cacheSize: UInt64 { get }

  • Removes all cached data

    Declaration

    Objective-C

    - (void)dropCache;

    Swift

    func dropCache()
