Question

我需要检测使用Swift 5且没有Internet连接的设备所在的国家/地区和状态。

reverseGeocodeLocation：

func getCityInLocation(from 
location:CLLocation,completion:@escaping(_city:String?, _ error:Error?) ->()) {
    CLGeocoder().reverseGeocodeLocation(location) { placemarks, error in
        completion(placemarks ?.first ?.locality, error)
    }
}

let location = CLLocation(latitude:19.339248,longitude:-99.191345)

getCityInLocation(from:location) { city, error in
    guard let city = city, error == nil else{
        return
    }

    print(city + "?Line 705")  //
}

您可以尝试执行此操作，这会为您提供来自蜂窝网络提供商的一些数据，但这仅适用于您自己的设备。不适用于其他用户...

let networkInfo = CTTelephonyNetworkInfo()
if let provider = networkInfo.serviceSubscriberCellularProviders?.first?.value {
                supportText += "\n Carrier: \(provider.carrierName ?? "None")"
                supportText += "\n ISO Location: \(provider.isoCountryCode ?? "None")"
                supportText += "\n Mobile Location: \(provider.mobileCountryCode ?? "None")"
}

如何在iOS中检测国家和州？
