iphone - iphone模拟器是否能够显示航向和纬度，经度？

Question

我正在使用 iphone 模拟器 4.2 并尝试显示或 NSLog 标题和其他位置服务属性，例如纬度、经度、高度、水平精度、垂直精度、速度。但它没有显示正确的参数和标题的 Incase 它实际上没有触发事件。作为其执行CLLocation代码

- (void)locationManager:(CLLocationManager *)manager
    didUpdateToLocation:(CLLocation *)newLocation
           fromLocation:(CLLocation *)oldLocation
{
    [self.delegate locationUpdate:newLocation];
}

并且不执行CLHeading代码

- (void)locationManager:(CLLocationManager *)manager didUpdateHeading:(CLHeading *)newHeading
{
    [self.delegate headingUpdate:newHeading];
}

当我在这两个代码上放置断点时，它永远不会触及 CLHeading 代码。我正在更新 init 中的位置和航向。

- (id) init{
if (self!=nil) {
    self.locationManager  = [[[CLLocationManager alloc] init] autorelease];
    self.locationManager.delegate = self;
    self.locationManager.desiredAccuracy = kCLLocationAccuracyBest;
    self.locationManager.distanceFilter = kCLDistanceFilterNone;
    [self.locationManager startUpdatingLocation];
    [self.locationManager startUpdatingHeading];
}
return self;
}

问题是不知道是模拟器问题还是代码有问题？

请帮忙。

CLLocationManager 需要额外的硬件，因此无法在模拟器上运行。但是，您可以使用 this other SO question 中描述的方法进行测试.

来自documentation :

Some location services require the presence of specific hardware on the given device. For example, heading information is available only for devices that contain a hardware compass. This class defines several methods that you can use to determine which services are currently available.
