MSFMBTilesTileDataSource

Objective-C


@interface MSFMBTilesTileDataSource : MSFTileDataSource

Swift

class MSFMBTilesTileDataSource : MSFTileDataSource

A tile data source that loads tiles from a local Sqlite database. The database must contain table “tiles” with the following fields: “zoom_level” (tile zoom level), “tile_column” (tile x coordinate), “tile_row” (tile y coordinate), “tile_data” (compressed tile image).

  • Constructs a MBTilesTileDataSource object. TMS tile scheme is used, Min and max zoom levels are automatically detected.

    Declaration

    Objective-C

    - (id)initWithPath:(NSString *)path;

    Swift

    init!(path: String!)

    Parameters

    path

    The path to the local Sqlite database file. @throws NSException If the the file could not be opened.

  • Constructs a MBTilesTileDataSource object. TMS tile scheme is used.

    Declaration

    Objective-C

    - (id)initWithMinZoom:(int)minZoom maxZoom:(int)maxZoom path:(NSString *)path;

    Swift

    init!(minZoom: Int32, maxZoom: Int32, path: String!)

    Parameters

    minZoom

    The minimum zoom level supported by this data source.
    maxZoom

    The maximum zoom level supported by this data source.
    path

    The path to the local Sqlite database file. @throws NSException If the the file could not be opened.

  • Constructs a MBTilesTileDataSource object with specified tile scheme.

    Declaration

    Objective-C

    - (id)initWithMinZoom:(int)minZoom
              maxZoom:(int)maxZoom
                 path:(NSString *)path
               scheme:(enum MSFMBTilesScheme)scheme;

    Swift

    init!(minZoom: Int32, maxZoom: Int32, path: String!, scheme: MSFMBTilesScheme)

    Parameters

    minZoom

    The minimum zoom level supported by this data source.
    maxZoom

    The maximum zoom level supported by this data source.
    path

    The path to the local Sqlite database file.
    scheme

    Tile scheme to use. @throws NSException If the the file could not be opened.
