如何在 - （void）locationManager中调用服务:( CLLocationManager *）管理器didUpdateToLocation只有一次？：

Question

我有一个应用程序，每当指定的位置发生更改时我都需要调用服务。我已经在我的委托类中启动了位置控制器，就像这样

    locationController = [[UILocation alloc] init];
    locationController.delegate = self;
    locationController.locationManager.desiredAccuracy = kCLLocationAccuracyBest;
    locationController.locationManager.distanceFilter = 1000.0;
    [locationController.locationManager startUpdatingLocation];  

但是每个人都知道Accuracybest会以不一致的方式多次调用didupdate方法。那么我怎样才能从委托方法中调用我的服务一次？有人能指出我如何实现这一目标吗？

Answer 1

-(void)postCurrentLocationOfDevice
{

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

}
-(void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations
{
   CURRENT_LOCATION = [locations objectAtIndex:0];
    [self.locationManager stopUpdatingLocation];

}

-(void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation
{
    CURRENT_LOCATION = newLocation;
    [self.locationManager stopUpdatingLocation];
}

Answer 2

-(void) locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation
{
[manager stopUpdatingLocation];
}

当第一次更新位置时，它将停止位置更新。
