MapKit，授予位置服务权限的运行方法

Question

I have an app with a mapkit that loads annotations during the ViewDidLoad using a loadAnnotations method. But I don't want to run said method (load the annotations) until permission is granted to use the current userLocation. Is this possible?

Answer 1

Yes it is possible. You request permission to use the users location using an instance of CLLocationManager (using [locationManager startUpdatingLocation] ). You need to set the delegate of your CLLocationManager and have it adhere to the CLLocationManagerDelegate protocol . Specifically, you want to use this method on your delegate:

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