                    features

The contents of the source.

If the receiver was initialized using -initWithSourceIdentifier:URL:, this property is set to nil. This property is unavailable until the receiver is passed into -[MGLStyle addSource].

Declaration

Objective-C

@property (readonly, nonatomic, nullable) NSArray<id<MGLFeature>> *features;

Swift

var features: [AnyObject]? { get }

                    geoJSONData

A GeoJSON representation of the contents of the source.

Use the features property instead to get an object representation of the contents. Alternatively, use NSJSONSerialization with the value of this property to transform it into Foundation types.

If the receiver was initialized using -initWithSourceIdentifier:URL:, this property is set to nil. This property is unavailable until the receiver is passed into -[MGLStyle addSource].

Declaration

Objective-C

@property (readonly, copy, nonatomic, nullable) NSData *geoJSONData;

Swift

@NSCopying var geoJSONData: NSData? { get }

URL

The URL to the GeoJSON document that specifies the contents of the source.

If the receiver was initialized using -initWithSourceIdentifier:geoJSONData:, this property is set to nil.

Declaration

Objective-C

@property (readonly, nonatomic, nullable) NSURL *URL;

Swift

var URL: NSURL? { get }
