Do not get permission from a user in MapKit

Question

First you need to call -[CLLocationManager requestWhenInUseAuthorization]or -[CLLocationManager requestAlwaysAuthorization]. Actually, I called this method in Didload and even added in info.plist, still getting this error.

    - (void)viewDidLoad {
    [super viewDidLoad];
    self.navigationItem.title = @"MapView";

    [MapView setMapType:MKMapTypeStandard];
    [MapView setZoomEnabled:YES];
    [MapView setScrollEnabled:YES];
    [MapView setShowsUserLocation:YES];
    MKCoordinateRegion region = { {0.0, 0.0 }, { 0.0, 0.0 } };
    region.center.latitude = 23.0804 ;
    region.center.longitude = 72.5241;
    region.span.longitudeDelta = 0.01f;
    region.span.latitudeDelta = 0.01f;
    [MapView setRegion:region animated:YES];

    [MapView setDelegate:self];

    CLLocationManager *locationManager = [[CLLocationManager alloc] init];
    locationManager.delegate = self;
    locationManager.distanceFilter = kCLDistanceFilterNone; //whenever we move
    locationManager.desiredAccuracy = kCLLocationAccuracyBest;

    [locationManager requestAlwaysAuthorization];
    [locationManager requestWhenInUseAuthorization];

    [locationManager startUpdatingLocation];

    Display *ann = [[Display alloc] init];
    ann.title = @" Gujarat";
    ann.subtitle = @"High Court";
    ann.coordinate = region.center;
    [MapView addAnnotation:ann];

}
-(MKAnnotationView *)mapView:(MKMapView *)mV viewForAnnotation:
(id <MKAnnotation>)annotation {
    MKPinAnnotationView *pinView = nil;
    if(annotation != MapView.userLocation)
    {
        static NSString *defaultPinID = @"com.invasivecode.pin";
        pinView = (MKPinAnnotationView *)[MapView dequeueReusableAnnotationViewWithIdentifier:defaultPinID];
        if ( pinView == nil ) pinView = [[MKPinAnnotationView alloc]
                                         initWithAnnotation:annotation reuseIdentifier:defaultPinID];

        pinView.pinColor = MKPinAnnotationColorRed;
        pinView.canShowCallout = YES;
        pinView.animatesDrop = YES;
        pinView.draggable = YES;
    }
    else {
        [MapView.userLocation setTitle:@"I am here"];
    }
    return pinView;
}


-(void)locationManager:(CLLocationManager *)manager didChangeAuthorizationStatus:(CLAuthorizationStatus)status

{

    if (status == kCLAuthorizationStatusAuthorizedWhenInUse)
    {
        [locationManager startUpdatingLocation];
    }
    else if (status == kCLAuthorizationStatusDenied)
    {
        //Alert to show for user if any when status is declined
    }
    else
        NSLog(@"Wrong location status");
}

and in the Display class for annotation

<MKAnnotation> {

    CLLocationCoordinate2D coordinate; 
    NSString *title; 
    NSString *subtitle;
}
@property (nonatomic, assign) CLLocationCoordinate2D coordinate; 
@property (nonatomic, copy) NSString *title; 
@property (nonatomic, copy) NSString *subtitle;

the code here does not display an invitation to obtain permission from the user to access his location, and because of this, we do not get the location of the desired place. Please help me be on it from yesterday.

Answer 1

There were actually two info.plist files, and I changed the values ​​in the Plest Demo Test plist files. when I added the key NSLocationAlwaysUsageDescriptionor NSLocationWhenInUseUsageDescriptionin Info.plist It Worked ..

Answer 2

, .

1) CLLocation Manager.  , CLLocation, CLLocationManager , .

2) "" > "" > " ". , . , , , .

3) , requestAlwaysAuthorization:

if ([_locationManager respondsToSelector:@selector(requestAlwaysAuthorization)]) {
    [_locationManager requestAlwaysAuthorization];
}

4) .

-(void)checkStatus{

CLAuthorizationStatus status = [CLLocationManager authorizationStatus];

if (status==kCLAuthorizationStatusNotDetermined) {
_status.text = @"Not Determined";
}

if (status==kCLAuthorizationStatusDenied) {
_status.text = @"Denied";
}

if (status==kCLAuthorizationStatusRestricted) {
_status.text = @"Restricted";
}

if (status==kCLAuthorizationStatusAuthorizedAlways) {
_status.text = @"Always Allowed";
}

if (status==kCLAuthorizationStatusAuthorizedWhenInUse) {
_status.text = @"When In Use Allowed";
  }

}

:

• CLLocationManager *locationManager . . , , , , .

• [locationManager startUpdatingLocation] , .

.plist:

NSLocationAlwaysUsageDescription or NSLocationWhenInUseUsageDescription key in Info.plist
