MKMapView mathod 'didUpdateUserLocation' not calling - ios

Question

I have this code in my file,
#synthesize myLocation;
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view.
self.locationManager = [[CLLocationManager alloc] init];
myLocation.delegate = self;
[self.locationManager requestWhenInUseAuthorization];
[myLocation setShowsUserLocation: YES];
}
- (void)mapView:(MKMapView *)mapView didUpdateUserLocation:(MKUserLocation *)userLocation
{
MKCoordinateRegion region = MKCoordinateRegionMakeWithDistance(userLocation.coordinate, 800, 800);
[self.myLocation setRegion:[self.myLocation regionThatFits:region] animated:YES];
}
But, method didUpdateUserLocation not calling.
I already added required frameworks in app.
I added everything in info.plist file. But still it is not calling.
This is my .h file,
#import <UIKit/UIKit.h>
#import <CoreLocation/CoreLocation.h>
#import <MapKit/MapKit.h>
#interface MapView : UIViewController <MKMapViewDelegate, CLLocationManagerDelegate>
#property (weak, nonatomic) IBOutlet MKMapView *myLocation;
#property(nonatomic, retain) CLLocationManager *locationManager;
#end

I just solved the problem,
locationManager = [[CLLocationManager alloc] init];
myLocation.delegate = self;
[locationManager requestWhenInUseAuthorization];
[locationManager startUpdatingLocation];
[myLocation setShowsUserLocation: YES];
Use setShowUserLocation with value YES after startUpdatingLocation

You have not called the method to update the location yet so the delegate method is not getting called. You need to call method for startUpdatingLocation.
For Objective - C:
[locationManager startUpdatingLocation];
For Swift:
locationManager.startUpdatingLocation()

Brother I tried your code.The delegate method is not called.
Then I found out the solution you did not add below line at the end of the viewDidLoad method. Please add
[self.locationManager startUpdatingLocation];
After I added above line code in viewDidLoad method,the delegate method called successfully.
