Why i am not able to fetch the location in Simulator?

Question

Question it self explain the detail, but still i have explained about the question.

I am new to fetch the location of the current Application. I have build one application that gives me the Current location in Text View.

But while i run that application in to xcode 4.0, I can't see any location to be fetch.

As i refer many example, i am right in coding. But now i want to know is IPhone Simulator able to fetch the current location ?

Answer 1

在iPhone模拟器中没有给出当前位置，但是应该可以在Device中工作，因此请在设备上尝试一下。

Answer 2

If you try it device current latitude and longitude will returns, but if you try it in simulator latitude=0 and longitude=0 will be return. Because user latitude and longitude is returns from GPS device which is in iPhone but not in simulator. So better you try it in device.

Answer 3

`in view did load

locationManager=[[CLLocationManager alloc] init];
    locationManager.delegate=self;
    appDelegate.IsFromRefreshPosition=YES;
    locationManager.desiredAccuracy = kCLLocationAccuracyNearestTenMeters;
if ([CLLocationManager locationServicesEnabled])
{
        [locationManager startUpdatingLocation];

}
geocoarder returns the plackmark of current location

- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation 

{   
    currentLocation = newLocation;
    [currentLocation retain];
    [locationManager stopUpdatingLocation];
     NSLog(@"%f   %f",currentLocation.coordinate.latitude,currentLocation.coordinate.longitude);
     geocoder = [[MKReverseGeocoder alloc] initWithCoordinate:currentLocation.coordinate];
     [geocoder setDelegate:self];
     [geocoder start];

}   

-(void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error 
{
    NSLog(@"locationManager:%@ didFailWithError:%@", manager, error);
}
-(void)reverseGeocoder:(MKReverseGeocoder *)geocoder1 didFindPlacemark:(MKPlacemark *)placemark
{
    NSLog(@"The geocoder has returned: %@",[placemark addressDictionary]);
    NSLog(@"CountryName :",[[placemark addressDictionary] objectForKey:@"Country"]);
    NSLog(@"cityName :",[[placemark addressDictionary] objectForKey:@"City"]);
        NSLog(@"After SubLocality %@",Addressstr);

    }

}
-(void)reverseGeocoder:(MKReverseGeocoder *)geocoder1 didFailWithError:(NSError *)error
{   
    NSLog(@"reverseGeocoder:%@ didFailWithError:%@", geocoder, error);
}

ITS WORK IN DEVICE FINE WITH ME
