在单独的线程上进行iPhone CoreLocation调用的最佳方法？

Question

有没有一种方法可以激发线程多次调用CoreLocation，然后每当它到达某个确定位置时都会更新UI？

Answer 1

Normally, you don't need a separate thread. In you CLLocationManagerDelegate , your -locationManager:didUpdateToLocation:fromLocation: method is called for every CL update. Check the accuracy (and possible the timestamp) and update your UI accordingly.
