How to set accuracy and distance filter when using MKMapView

For displaying map here is an example code.

First import MKMapKit and CoreLocation framework in your .h file.

#import <MapKit/MapKit.h>
 #import <CoreLocation/CoreLocation.h>

Add MKMapKit and CoreLocation Delegate in .h file

@interface MapViewController : UIViewController <MKMapViewDelegate, CLLocationManagerDelegate>


CGPoint gameMapCenter = CGPointMake([[UIScreen mainScreen] bounds].size.width / 2, [[UIScreen mainScreen] bounds].size.height / 2);
    gameMapView = [[MKMapView alloc] initWithFrame:CGRectMake(0, 0, 640, 620)];
    [gameMapView setCenter:gameMapCenter];
    [gameMapView setMapType:MKMapTypeStandard];
    [gameMapView setDelegate:self];
    [self.view addSubview:gameMapView];
    [gameMapView setShowsUserLocation:YES];

Use CLLocationManager for fetching user location.

Declare an instance of CLLocationManager

CLLocationManager *locationManager;

In ViewDidLoad

locationManager = [[CLLocationManager alloc] init];

[locationManager setDelegate:self];

[locationManager setDesiredAccuracy:kCLLocationAccuracyBest];

[locationManager setDistanceFilter:kCLDistanceFilterNone];

[locationManger startUpdatingLocation];

startUpdatingLocation Method Implementation:

(void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation 
{
      //Your Stuff
}
