把CLLocationManager设置为属性。
这里有一个坑点,如果不设置为属性,软件开启时提示定位的提示出现一瞬间就消失了。

self.locationManager.delegate = self;
//控制定位精度,越高耗电量越
self.locationManager.desiredAccuracy = kCLLocationAccuracyKilometer;
// 总是授权
[self.locationManager requestAlwaysAuthorization];
self.locationManager.distanceFilter = 10.0f;
[self.locationManager requestAlwaysAuthorization];
[self.locationManager startUpdatingLocation];
}
