Maintained by Mattt.

You want to add pod 'GeoJSONSerialization', '~> 0.0' similar to the following to your Podfile:

target 'MyApp' do
  pod 'GeoJSONSerialization', '~> 0.0'

GeoJSONSerialization encodes and decodes between GeoJSON and MapKit shapes, following the API conventions of Foundation's NSJSONSerialization class.

Usage

Decoding

#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.
