读取
// NSString *content = ...
SFGGeometry *geometry = [SFGFeatureConverter jsonToGeometry:content];
SFGeometry *simpleGeometry = [geometry geometry];
/* Read as a generic GeoJSON object, Feature, or Feature Collection */
// SFGGeoJSONObject *geoJSONObject = [SFGFeatureConverter jsonToObject:content];
// SFGFeature *feature = [SFGFeatureConverter jsonToFeature:content];
// SFGFeatureCollection *featureCollection = [SFGFeatureConverter jsonToFeatureCollection:content];
写入
// SFGeometry *geometry = ...
NSString *content = [SFGFeatureConverter simpleGeometryToJSON:geometry];
SFGFeature *feature = [SFGFeatureConverter simpleGeometryToFeature:geometry];
NSString *featureContent = [SFGFeatureConverter objectToJSON:feature];
SFGFeatureCollection *featureCollection = [SFGFeatureConverter simpleGeometryToFeatureCollection:geometry];
NSString *featureCollectionContent = [SFGFeatureConverter objectToJSON:featureCollection];
NSDictionary *contentTree = [SFGFeatureConverter simpleGeometryToTree:geometry];

读取
// var content: String = ...
let geometry: SFGGeometry = SFGFeatureConverter.json(toGeometry: content)
let simpleGeometry: SFGeometry = geometry.geometry()
/* Read as a generic GeoJSON object, Feature, or Feature Collection */
// let geoJSONObject : SFGGeoJSONObject = SFGFeatureConverter.json(toObject: content)
// let feature: SFGFeature = SFGFeatureConverter.json(toFeature: content)
// let featureCollection : SFGFeatureCollection = SFGFeatureConverter.json(toFeatureCollection: content)
写入
// let geometry : SFGeometry = ...
let content : String = SFGFeatureConverter.simpleGeometry(toJSON: geometry)
let feature : SFGFeature = SFGFeatureConverter.simpleGeometry(toFeature: geometry)
let featureContent : String = SFGFeatureConverter.object(toJSON: feature)
let featureCollection : SFGFeatureCollection = SFGFeatureConverter.simpleGeometry(toFeatureCollection: geometry)
let featureCollectionContent : String = SFGFeatureConverter.object(toJSON: featureCollection)
let contentTree : Dictionary = SFGFeatureConverter.simpleGeometry(toTree: geometry)
