objective-c - WatchOS 模拟器中的位置检测失败

Question

如何模拟 watchOS 模拟器的位置？

与请求一起使用

- (void) requestLocation {
    locationManager = [CLLocationManager new];

    locationManager.delegate = self;

    [locationManager requestWhenInUseAuthorization];
    [locationManager requestLocation];
}

我总是遇到一个错误：

- (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error {
        // Error here if no location can be found
}

错误是 NSError * domain: @"kCLErrorDomain" - code: 0 0x7a867970

为了在手表模拟器中进行位置检测，您还需要设置 iPhone 模拟器的位置。我建议您按照以下步骤操作

1. 在 iPhone 模拟器中设置位置，（调试 -> 位置 -> 自定义位置）
2. 在手表模拟器中设置位置，（调试->位置->自定义位置）
3. 有时，当您运行 watchkit 应用程序时，iPhone 模拟器中的位置会重置为无。因此，在您访问该位置之前，在手表扩展代码中放置断点。在两个模拟器中都设置了检查位置。

希望这可以帮助。

快速示例代码，

class LocationManager: NSObject, CLLocationManagerDelegate
{
static let sharedInstance = VCLocationManager()
private var locationManager : CLLocationManager?

private override init()
{

}

func initLocationMonitoring()
{
    //didChangeAuthorizationStatus is called as soon as CLLocationManager instance is created.
    //Thus dont check authorization status here because it will be always handled.

    if locationManager == nil
    {
        locationManager = CLLocationManager()
        locationManager?.desiredAccuracy = kCLLocationAccuracyBest
        locationManager?.delegate = self
    }
    else
    {
        getCurrentLocation()
    }
}

func getCurrentLocation()
{
    let authorizationStatus = CLLocationManager.authorizationStatus()
    handleLocationServicesAuthorizationStatus(authorizationStatus)
}

 func handleLocationServicesAuthorizationStatus(status: CLAuthorizationStatus)
{
    switch status
    {
    case .NotDetermined:
        handleLocationServicesStateNotDetermined()
    case .Restricted, .Denied:
        handleLocationServicesStateUnavailable()
    case .AuthorizedAlways, .AuthorizedWhenInUse:
        handleLocationServicesStateAvailable()
    }
}

func handleLocationServicesStateNotDetermined()
{
    locationManager?.requestWhenInUseAuthorization()
}

func handleLocationServicesStateUnavailable()
{
    //Ask user to change the settings through a pop up.
}

func handleLocationServicesStateAvailable()
{
    locationManager?.requestLocation()
}

func locationManager(manager: CLLocationManager, didChangeAuthorizationStatus status: CLAuthorizationStatus)
{
    handleLocationServicesAuthorizationStatus(status)
}

func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation])
{
    guard let mostRecentLocation = locations.last else { return }
    print(mostRecentLocation)
}

func locationManager(manager: CLLocationManager, didFailWithError error: NSError)
{
    print("CL failed: \(error)")
}
 }
