The other answers are incorrect. You can request location directly on the watch for watch OS2. The available method is called requestLocation. It allows you to request a single location update.

其他的答案是不正确的。您可以直接在手表上为watch OS2请求位置。可用的方法称为requestLocation。它允许您请求单个位置更新。

E.g.

如。

#import <CoreLocation/CoreLocation.h>
@interface className : WKInterfaceController<CLLocationManagerDelegate>

Then where you want to request location:

然后在你想要请求位置的地方:

self.locationManager = [CLLocationManager new];
self.locationManager.delegate = self;
[self.locationManager requestWhenInUseAuthorization];
[self.locationManager requestLocation];

Then you will get a single callback in one of the following CLLocationManagerDelegate methods.

然后，您将在以下CLLocationManagerDelegate方法之一中获得一个回调。

- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations {
    // Callback here with single location if location succeeds
}

- (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error {
    // Error here if no location can be found
}
