CLLocationManager 没有给我我的位置
这是我的代码
CLLocationManager* locationManager = [[[CLLocationManager alloc]init]autorelease];
locationManager.delegate = self;
locationManager.desiredAccuracy = kCLLocationAccuracyBest;
locationManager.distanceFilter = kCLDistanceFilterNone;
[locationManager startUpdatingLocation];
NSLog(@"Latitude :%f",locationManager.location.coordinate.latitude);
CLLocation* currentLocation = [locationManager location];
_drivingReverseGeocoder = [[MKReverseGeocoder alloc] initWithCoordinate:[currentLocation coordinate]];
[_drivingReverseGeocoder setDelegate:self];
[_drivingReverseGeocoder start];
当我执行 NSLog 时，我的 long 和 lat 是 0.000000。另外，我正在使用模拟器，但我希望我的经度和纬度在我当前位置所在的位置处于无限循环。有人有任何见解吗？
Here is my code
CLLocationManager* locationManager = [[[CLLocationManager alloc]init]autorelease];
locationManager.delegate = self;
locationManager.desiredAccuracy = kCLLocationAccuracyBest;
locationManager.distanceFilter = kCLDistanceFilterNone;
[locationManager startUpdatingLocation];
NSLog(@"Latitude :%f",locationManager.location.coordinate.latitude);
CLLocation* currentLocation = [locationManager location];
_drivingReverseGeocoder = [[MKReverseGeocoder alloc] initWithCoordinate:[currentLocation coordinate]];
[_drivingReverseGeocoder setDelegate:self];
[_drivingReverseGeocoder start];
When I do my NSLog my long and lat are 0.000000. Also, I am using the simulator but I expected my long and lat to be at infinite loop where my current location is. Does anyone have any insight?

删除 startUpdatingLocation 之后的所有内容，并在类中实现此方法，该方法是 CLLocationManagerDelegate 协议的一部分：
- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation
{
// 此处使用 newLocation
。
另外，在实际设备上进行测试
Remove everything after startUpdatingLocation and implement this method in your class, which is part of the CLLocationManagerDelegate protocol:
- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation
{
// use newLocation here
}
Also, test on an actual device.
