Current location permission dialog disappears too quickly

I met same situation of yours.

- My solution was changed from local variable to member instance.
- The cause was that the local?instance was invalid after the method was finished which includes the local the variable(of extend my locationManager)
- My Env.: Xcode9.3.1

<pre>

#import <MyLocationService.h>
@interface ViewController ()

@end

@implementation ViewController
@synthesize locManager; // after
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.

//MyLocationService *locManager = [[BSNLocationService alloc]init:nil]; // before. the loc. delegate did not work because the instance became invalid after this method.
self->locManager= [[MyLocationService alloc]init:nil]; // after
locManager.startService;
}

</pre>

I have faced the similar situation. After debugging I found

```
let locationManager = CLLocationManager()
```

is called in a method scope, but it should be called globally.

Why?

In a nutshell, locationManager has been released after the method had returned. But it shouldn't be released until user give or deny permission

I had the `locationManager` as instance var but still that did not help in Swift 5, Xcode 11 (see below):


class MapViewController: UIViewController {

var locationManager: CLLocationManager {
let locationManager = CLLocationManager()
locationManager.desiredAccuracy = .greatestFiniteMagnitude
locationManager.delegate = self
locationManager.requestWhenInUseAuthorization()
return locationManager
}

override func viewDidLoad() {
super.viewDidLoad()
locationManager.startUpdatingLocation()
}
}



However, making `locationManager` var lazy fixed the issue:

class MapViewController: UIViewController {

lazy var locationManager: CLLocationManager = {
let locationManager = CLLocationManager()
locationManager.desiredAccuracy = .greatestFiniteMagnitude
locationManager.delegate = self
locationManager.requestWhenInUseAuthorization()
return locationManager
}()

override func viewDidLoad() {
super.viewDidLoad()
locationManager.startUpdatingLocation()
}
}
