为什么我无法在模拟器中获取位置？

Question

问它自我解释的细节，但我仍然解释了这个问题。

我是新来获取当前应用程序的位置。我已经构建了一个应用程序，可以在文本视图中为我提供当前位置。

但是，当我运行该应用程序到xcode 4.0，我看不到任何位置要获取。

正如我提到的很多例子，我是正确的编码。但现在我想知道的是iPhone模拟器能够获取当前位置？

Answer 1

在iPhone模拟器不给currentlocation.But它应该在Device.So尝试它在设备上。

Answer 2

以下代码将允许向您显示用户的当前位置;

[mapView setShowsUserLocation:YES]; 

Answer 3

如果您尝试设备当前的经纬度将返回，但如果您尝试在模拟器纬度= 0和经度= 0将返回。因为用户的经度和纬度是从iPhone中的设备返回的，但不在模拟器中。所以你最好在设备上试试它。

Answer 4

`鉴于没有负载

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); 
} 

其工作设备我都没
