CLLocationManager无法在iOS 4.3模拟器中运行

Question

我正在使用CLLocationManager来确定我当前的位置：

- (void)viewDidLoad
{
    locationManager = [[CLLocationManager alloc] init];
    [locationManager setDelegate:self];
    [locationManager startUpdatingLocation];
}

- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation 
{
    self.currentLocation = newLocation;
    NSTimeInterval locationAge = -[newLocation.timestamp timeIntervalSinceNow];
    if (locationAge > 5.0) return;
    if (newLocation.horizontalAccuracy < 0) return;
    if (self.currentLocation == nil || self.currentLocation.horizontalAccuracy > newLocation.horizontalAccuracy) {
        self.currentLocation = newLocation;
    }
    [locationManager stopUpdatingLocation];
}

它适用于iOS 5.1模拟器，但不适用于iOS 4.3模拟器，我认为它可能是iOS 5.1之前的真实设备中的问题。为什么不起作用？

Answer 1

iOS模拟器在iOS 5之前不支持模拟位置。您遇到的问题是模拟器的限制。
