cllocationmanger class location updates - iphone

Question

I am doing one application.In that i am using the CLLOcationmanager like below.
[self performSelectorOnMainThread:#selector(findlocation:) withObject:nil waitUntilDone:NO];
-(void)findlocation:(id)sender
{
//NSAutoreleasePool *pool=[[NSAutoreleasePool alloc]init];
locationManager=[[CLLocationManager alloc]init];
locationManager.delegate=self;
locationManager.distanceFilter=0.3f;
locationManager.desiredAccuracy = kCLLocationAccuracyBest;
[locationManager startUpdatingLocation];
}
- (void)locationManager:(CLLocationManager *)manager
didUpdateToLocation:(CLLocation *)newLocation
fromLocation:(CLLocation *)oldLocation
{
NSLog#"%#",newlocation.timestamp];
}
I want to update the location for every 0.3 meters.But this delegate method is not fired for that distance. And after [self performSelectorOnMainThread:#selector(findlocation:) withObject:nil waitUntilDone:NO]; my remaining process is working.

I think this may help you. You need to adjust distance using longitude and latitude
- (void)locationManager:(CLLocationManager *)manager
didUpdateToLocation:(CLLocation *)newLocation
fromLocation:(CLLocation *)oldLocation {
MKCoordinateRegion region = { { 0.0f, 0.0f }, { 0.0f, 0.0f } };
region.center = newLocation.coordinate;
region.span.longitudeDelta = 0.15f;
region.span.latitudeDelta = 0.15f;
[self.mapView setRegion:region animated:YES];
}
Above code uses 0.15 degrees (0.15*111 Km).
OR try to use you distanceFilter".Using distanceFilter allows you to filter out that kind of extraneous motion.
