在iPhone OS 4.0中未调用CLLocationManager Delegate

Question

我必须在iPhone OS 4.0中运行我的应用程序。 （在模拟器中）。

-(BOOL)application:(UIApplication *)application
didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    [self newLocationUpdate];
}

-(void)newLocationUpdate
{
    locationManager = [[CLLocationManager alloc] init];
    locationManager.delegate = self;
    [locationManager startUpdatingLocation];

}

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

在此CLLocationManager中，委托方法未被调用。我们应该做什么改变才能调用委托方法？
