如何获得指定精度的一次性位置？
在文档中，它说它获得了一个大概的位置，然后以越来越精细的精度不断更新。我有一个按钮
[locManager startUpdatingLocation];
，然后我实施
- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation{
[locManager stopUpdatingLocation];
}
并让它在某个地方得到指示。由于某种原因，当我开车去某个地方时，它不会更新位置。我认为这是因为它获得了“大致位置”，然后没有足够的时间来获得准确的读数。我也有
locManager.desiredAccuracy = kCLLocationAccuracyBestForNavigation;
什么想法吗？只需要一次准确的读数。难住了。谢谢。
In the documentation it says that it gets an approximate location and then keeps updating with finer and finer precision. I have a button that does
[locManager startUpdatingLocation];
and then I implement
- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation{
[locManager stopUpdatingLocation];
}
and have it get directions somwhere. For some reason it's not updating locations when I drive somewhere. I would assume this is because it gets the "general location", and then doesn't have enough time to get an accurate reading. I also have
locManager.desiredAccuracy = kCLLocationAccuracyBestForNavigation;
Any thoughts? just need one time accurate readings. stumped. thanks.

快速破解解决方案：
更好的解决方案可能是等到准确性停止提高（根据最近 5 次更新的平均值）。
Quick hack solution:
A better solution might be to wait until accuracy stops improving, averaged over the last 5 updates or so.
