我可以获得iOS中GPS定位的准确性吗？

Question

我见过Android开发人员可以获得GPS位置的准确性.有没有办法让我在iOS中获得我当前GPS定位的准确性？

我正在使用此答案中的代码来获取我的位置:

 locationManager = [[CLLocationManager alloc] init];
 locationManager.delegate = self;
 locationManager.distanceFilter = kCLDistanceFilterNone;
 locationManager.desiredAccuracy = kCLLocationAccuracyBest;
 [locationManager startUpdatingLocation];


 - (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation {
     NSLog(@"OldLocation %f %f", oldLocation.coordinate.latitude, oldLocation.coordinate.longitude);
     NSLog(@"NewLocation %f %f", newLocation.coordinate.latitude, newLocation.coordinate.longitude);
 }

Answer 1

上有2个属性CLLocation -horizontalAccuracy和-verticalAccuracy.大多数情况下,准确性取决于您用于获取位置的硬件

Answer 2

horizontalAccuary中CLLocation给出了相关的纬度米的估计位置误差,经度坐标.

verticalAccuracy给出与之相关的估计误差altitude.
