//parse out the json data
NSError* error;
NSDictionary* json = [NSJSONSerialization

...
NSArray *markerForplaces = [NSMutableArray arrayWithCapacity:[responseResults count]];
for (NSDictionary *dict in responseResults) {
GMSMarker *markerForplace = [self markerForGooglePlaceFromDictionary:dict error:nil];
if (markerForplace) {
[markerForplaces addObject:markerForplace];
markerForplace.map = self.mapView;
}
}
...
- (GMSMarker*)markerForGooglePlaceFromDictionary:(NSDictionary*)dict {
CLLocationCoordinate2D coordinate = [self coordinateForPlace:dict];
GMSMarker *marker = [GMSMarker markerWithPosition:coordinate];
marker.userInfo = dict; //save place
}
- (CLLocationCoordinate2D)coordinateForPlace:(NSDictionary*)dictionary {
NSDictionary *geo = [dictionary objectForKey:#"geometry"];
if ([geo isKindOfClass:[NSDictionary class]]) {
NSDictionary *loc = [geo objectForKey:#"location"];
if ([loc isKindOfClass:[NSDictionary class]]) {
NSString *lat = [loc objectForKey:#"lat"];
NSString *lng = [loc objectForKey:#"lng"];
return CLLocationCoordinate2DMake([lat doubleValue], [lng doubleValue]);
}
}
return CLLocationCoordinate2DMake(0, 0);
