MGLSource
@interface MGLSource : NSObject
MGLSource
is an abstract base class for map content sources. A map content source supplies content to be shown on the map. A source is added to an MGLStyle
object along with an MGLForegroundStyleLayer
object. The foreground style layer defines the appearance of any content supplied by the source.
Each source defined by the style JSON file is represented at runtime by an MGLSource
object that you can use to refine the map’s content. You can also add and remove sources dynamically using methods such as -[MGLStyle addSource:]
and -[MGLStyle sourceWithIdentifier:]
.
Create instances of MGLShapeSource
, MGLComputedShapeSource
, MGLImageSource
, and the concrete subclasses of MGLTileSource
(MGLVectorTileSource
and MGLRasterTileSource
) in order to use MGLSource
’s properties and methods. Do not create instances of MGLSource
directly, and do not create your own subclasses of this class.
Initializing a Source
-initWithIdentifier:
Returns a source initialized with an identifier.
After initializing and configuring the source, add it to a map view’s style using the -[MGLStyle addSource:]
method.
Declaration
Objective-C
- (nonnull instancetype)initWithIdentifier:(nonnull NSString *)identifier;
Swift
init(identifier: String)
Parameters
identifier
A string that uniquely identifies the source in the style to which it is added.
Return Value
An initialized source.
Identifying a Source
identifier
A string that uniquely identifies the source in the style to which it is added.
Declaration
Objective-C
@property (nonatomic, copy, readwrite) NSString *_Nonnull identifier;
Swift
var identifier: String { get set }
