CLGeocoder().geocodeAddressString错误代码

Question

我正在做一个项目，在这个项目中，我使用CLGeocoder来确定特定位置的地标。非常简单的调用，像这样。

CLGeocoder().geocodeAddressString(location) { (placemarks, error) in
            if let error = error {
                print(error.localizedDescription)
            }

我希望能够捕获CLError代码并做出相应的响应，而不是打印出NSError的localizedDescription。例如，如果找不到位置，我的localizedDescription将打印

The operation couldn’t be completed. (kCLErrorDomain error 8.)

我如何在Swift中确定CLError代码，这样我就不必打开一些本地化的描述，这些描述将根据用户的区域设置进行更改？这可以做到吗？我只有几个案子想换。

您需要将错误类型转换为CLError，然后切换错误code

if let error = error as? CLError { 
    switch error.code {
    case .locationUnknown:
        print("locationUnknown: location manager was unable to obtain a location value right now.")
    case .denied:
        print("denied: user denied access to the location service.")
    case .promptDeclined:
        print("promptDeclined: user didn’t grant the requested temporary authorization.")
    case .network:
        print("network: network was unavailable or a network error occurred.")
    case .headingFailure:
        print("headingFailure: heading could not be determined.")
    case .rangingUnavailable:
        print("rangingUnavailable: ranging is disabled.")
    case .rangingFailure:
        print("rangingFailure: a general ranging error occurred.")
    default : break
    }
}
