didFailWithError: Error Domain=kCLErrorDomain Code=0 "操作无法完成。(kCLErrorDomain错误0。)"

我想获取当前位置，但却收到了错误提示。

以下是我的视图控制器代码片段。

- (void)viewDidLoad {
    self.locationManager = [[CLLocationManager alloc] init];
    [locationManager setDelegate:self];
    [locationManager setDesiredAccuracy:kCLLocationAccuracyNearestTenMeters];
    [locationManager startUpdatingLocation];
}

- (void)locationManager:(CLLocationManager *)manager 
     didUpdateLocations:(NSArray<CLLocation *> *)locations {
    // I would get the latest location here
    // but this method never gets called
}
- (void)locationManager:(CLLocationManager *)manager 
       didFailWithError:(NSError *)error {
    NSLog(@"didFailWithError: %@", error);
}

我期望委托方法locationManager:didUpdateLocations:被调用，但实际上只有locationManager:didFailWithError:被调用，并打印出以下内容：

didFailWithError: Error Domain=kCLErrorDomain Code=0 "The operation couldn’t be completed. (kCLErrorDomain error 0.)"
