# GeoJSONSerialization

> This library is no longer maintained.
> In iOS 13+ and macOS 10.15+, use [`MKGeoJSONDecoder`](https://developer.apple.com/documentation/mapkit/mkgeojsondecoder) instead.

`GeoJSONSerialization` encodes and decodes between
[GeoJSON](http://geojson.org) and
[MapKit](https://developer.apple.com/documentation/MapKit) shapes,
following the API conventions of Foundation's `NSJSONSerialization` class.

## Usage

### Decoding

```objective-c
#import <MapKit/MapKit.h>
#import "GeoJSONSerialization.h"

NSURL *URL = [[NSBundle mainBundle] URLForResource:@"map" withExtension:@"geojson"];
NSData *data = [NSData dataWithContentsOfURL:URL];
NSDictionary *geoJSON = [NSJSONSerialization JSONObjectWithData:data options:0 error:nil];
NSArray *shapes = [GeoJSONSerialization shapesFromGeoJSONFeatureCollection:geoJSON error:nil];

for (MKShape *shape in shapes) {
    if ([shape isKindOfClass:[MKPointAnnotation class]]) {
        [mapView addAnnotation:shape];
    } else if ([shape conformsToProtocol:@protocol(MKOverlay)]) {
        [mapView addOverlay:(id <MKOverlay>)shape];
    }
}
```

> After implementing the necessary `MKMapViewDelegate` methods,
> the resulting map will look
> [something like this](https://github.com/mattt/GeoJSONSerialization/blob/master/Example/iOS%20Example/map.geojson).
