CoreLocation框架问题

Question

我已经使用Core位置框架在我的IPOD中接收我的GPS坐标。第一次我可以获得纬度和经度，然后我收到错误消息，kCLErrorDomain Code = 0操作无法完成。

但是错误信息永远不会改变。我想第一次只有它起作用

这是我的代码

#import "CoreLocationDemoViewController.h"

@implementation CoreLocationDemoViewController

@synthesize CLController;

- (void)viewDidLoad {
    [super viewDidLoad];

    CLController = [[CoreLocationController alloc] init];
    CLController.delegate = self;
    [CLController.locMgr startUpdatingLocation];
}

- (void)locationUpdate:(CLLocation *)location {
    speedLabel.text = [NSString stringWithFormat:@"SPEED: %f", [location speed]];
    latitudeLabel.text = [NSString stringWithFormat:@"LATITUDE: %f", location.coordinate.latitude];
    longitudeLabel.text = [NSString stringWithFormat:@"LONGITUDE: %f", location.coordinate.longitude];
    altitudeLabel.text = [NSString stringWithFormat:@"ALTITUDE: %f", [location altitude]];
    errorLabel.text = @"";
}

- (void)locationError:(NSError *)error {

    if(!CLController) //.text )
    {   
    errorLabel.text = [error description];
    }
}

- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
}

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation {
    return YES;
}

- (void)viewDidUnload {
}

- (void)dealloc {
    [CLController release];
    [super dealloc];
}

@end

任何人都知道有什么问题，非常感谢帮助。

谢谢， VKS

是iPod没有GPS功能。在模拟器或iPhone中测试您的应用程序，而不是在iPod上。
