iOS 8 Map Kit Obj-C : Get Users Location

In your .plist Add a new row with the key name:




Define the header:

#define IS_OS_8_OR_LATER ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0)

Update your files with following code:


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

@interface YourViewController : UIViewController <MKMapViewDelegate,  CLLocationManagerDelegate> {


@property(nonatomic, retain) IBOutlet MKMapView *mapView;
@property(nonatomic, retain) CLLocationManager *locationManager;


- (void)viewDidLoad
    [super viewDidLoad];
    // Do any additional setup after loading the view.

    mapView.delegate = self;
    self.locationManager = [[CLLocationManager alloc] init];
    self.locationManager.delegate = self;
    #ifdef __IPHONE_8_0
    if(IS_OS_8_OR_LATER) {
         // Use one or the other, not both. Depending on what you put in info.plist
        [self.locationManager requestWhenInUseAuthorization];
        [self.locationManager requestAlwaysAuthorization];
    [self.locationManager startUpdatingLocation];

    mapView.showsUserLocation = YES;
    [mapView setMapType:MKMapTypeStandard];
    [mapView setZoomEnabled:YES];
    [mapView setScrollEnabled:YES];

-(void)viewDidAppear:(BOOL)animated {
    [super viewDidAppear:YES];

    self.locationManager.distanceFilter = kCLDistanceFilterNone;
    self.locationManager.desiredAccuracy = kCLLocationAccuracyBest;
    [self.locationManager startUpdatingLocation];
    NSLog(@"%@", [self deviceLocation]);

    //View Area
    MKCoordinateRegion region = { { 0.0, 0.0 }, { 0.0, 0.0 } }; = self.locationManager.location.coordinate.latitude; = self.locationManager.location.coordinate.longitude;
    region.span.longitudeDelta = 0.005f;
    region.span.longitudeDelta = 0.005f;
    [mapView setRegion:region animated:YES];


- (void)mapView:(MKMapView *)mapView didUpdateUserLocation:(MKUserLocation *)userLocation
    MKCoordinateRegion region = MKCoordinateRegionMakeWithDistance(userLocation.coordinate, 800, 800);
    [self.mapView setRegion:[self.mapView regionThatFits:region] animated:YES];

- (NSString *)deviceLocation {
    return [NSString stringWithFormat:@"latitude: %f longitude: %f", self.locationManager.location.coordinate.latitude, self.locationManager.location.coordinate.longitude];

How to add an Objective-C file in your Swift Project? or How to set Objective-C bridging header?

Bridging header
Bridging header

To import a set of Objective-C files in the same app target as your Swift code, you rely on an Objective-C bridging header to expose those files to Swift. Xcode offers to create this header file when you add an Objective-C file to an existing Swift app.

If you accept, Xcode creates the header file along with the file you were creating, and names it by your product module name followed by adding “-Bridging-Header.h”.

Alternatively, you can create a bridging header yourself by choosing File > New > File > (iOS or OS X) > Source > Header File.

You’ll need to edit the bridging header file to expose your Objective-C code to your Swift code.

To import Objective-C code into Swift from the same target

  1. In your Objective-C bridging header file, import every Objective-C header you want to expose to Swift.

    For example:

        #import "XYZCustomCell.h"
        #import "XYZCustomView.h"
        #import "XYZCustomViewController.h"
  2. Under Build Settings, make sure the Objective-C Bridging Header build setting under Swift Compiler – Code Generation has a path to the header.

    The path should be relative to your project, similar to the way your Info.plist path is specified in Build Settings. In most cases, you should not need to modify this setting.

Any public Objective-C headers listed in this bridging header file will be visible to Swift. The Objective-C functionality will be available in any Swift file within that target automatically, without any import statements. Use your custom Objective-C code with the same Swift syntax you use with system classes.

For Example:

    let myCell = XYZCustomCell()
    myCell.subtitle = "A custom cell"
