The style associated with the tileset descriptor
Declaration
Objective-C
@property (nonatomic, copy, readonly, nonnull) NSString *styleURI;
Swift
var styleURI: String { get }
-
Minimum zoom level for the tile package.
Note: the implementation loads and stores the loaded tiles in batches, each batch has a pre-defined zoom range and it contains all child tiles within the range. The zoom leveling scheme for the tile batches can be defined in Tile JSON, otherwise the default scheme is used:
- Global coverage: 0 - 5
- Regional information: 6 - 10
- Local information: 11 - 14
- Streets detail: 15 - 16
Internally, the implementation maps the given tile pack zoom range and geometry to a set of pre-defined batches to load, therefore it is highly recommended to choose the
minZoom
andmaxZoom
values in accordance with the tile batches zoom ranges (see the list above).Declaration
Objective-C
@property (nonatomic, readonly) uint8_t minZoom;
Swift
var minZoom: UInt8 { get }
-
Maximum zoom level for the tile package.
maxZoom value cannot exceed the maximum allowed tile batch zoom value,
See
minZoom
Declaration
Objective-C
@property (nonatomic, readonly) uint8_t maxZoom;
Swift
var maxZoom: UInt8 { get }
-
Pixel ratio to be accounted for when downloading raster tiles.
The
pixelRatio
must be ≥ 0 and should typically be 1.0 or 2.0.Declaration
Objective-C
@property (nonatomic, readonly) float pixelRatio;
Swift
var pixelRatio: Float { get }
-
Style package load options, associated with the tileset descriptor.
If provided,
offline manager
will create a style package while resolving the corresponding tileset descriptor and load all the resources as defined in the provided style package options, i.e. resolving of corresponding the tileset descriptor will be equivalent to calling theloadStylePack
method ofoffline manager
. If not provided, resolving of the corresponding tileset descriptor will not cause creating of a new style package but the loaded resources will be stored in the disk cache.Declaration
Objective-C
@property (nonatomic, readonly, nullable) MBMStylePackLoadOptions *stylePackOptions;
Swift
var stylePackOptions: MBMStylePackLoadOptions? { get }
