我试图通过coreLocation获取用户在Apple Watch上的当前位置。每当我运行-[CLLocationManager requestLocation]时，应用程序都会退出并给出以下错误。

This is my code:
locationManager = [[CLLocationManager alloc] init];
locationManager.delegate = self;
[locationManager requestWhenInUseAuthorization];
[locationManager requestLocation];
如果您有更好的获取用户位置的方法，也请告诉我。
最佳答案
根据错误消息，'Delegate must respond to locationManager:didUpdateLocations:'我必须在我的委托中实现locationManager:didUpdateLocations:和locationManager:didFailWithError:才能使用requestLocation。
