iOS 8 Map Kit Obj-C Cannot Get Users Location

I got it working. I’ve posted my code below to help anyone else having issues.

Here is my full code to get the MapKit Map View working in iOS 8.

In your AppName-Info.plist
Add a new row with the key name being:

NSLocationWhenInUseUsageDescription

Or

NSLocationAlwaysUsageDescription

With the value being a string of the message that you want to be displayed:

YourAppName would like to use your location.

In your header file. (I use App Name-Prefix.pch but YourViewController.h will work too)

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

YourViewController.h

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

@interface YourViewController : UIViewController <MKMapViewDelegate,  CLLocationManagerDelegate> {

}


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

YourViewController.m

- (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];
    }
    #endif
    [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 } };
    region.center.latitude = self.locationManager.location.coordinate.latitude;
    region.center.longitude = 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];
}
- (NSString *)deviceLat {
    return [NSString stringWithFormat:@"%f", self.locationManager.location.coordinate.latitude];
}
- (NSString *)deviceLon {
    return [NSString stringWithFormat:@"%f", self.locationManager.location.coordinate.longitude];
}
- (NSString *)deviceAlt {
    return [NSString stringWithFormat:@"%f", self.locationManager.location.altitude];
}

Enjoy!
