如何在 swift 中使用 CoreLocation 从英国邮政编码获取自治市镇？

Question

有谁知道我是否可以使用 CoreLocation 框架从英国邮政编码中获取自治市镇？在下面列出的函数中，不返回自治市镇。它应该返回 Tower Hamlets。

  func getLocationFrom(postalCode : String){
    let geocoder = CLGeocoder()

    geocoder.geocodeAddressString(postalCode) {
        (placemarks, error) -> Void in
        let placemark = placemarks?[0] 
             print("placemark.addressDictionary are \(placemark.addressDictionary)") //does not print Canary Wharf  
    }
}

print(getLocationFrom(postalCode:"E14 9LR")) //does not print Tower Hamlets, it prints London, which is the city, not the borough..

为了从邮政编码中获取位置，您只需为 placemarks 数组下标，然后访问所需 indexPath 处元素的属性 locality。我的错误是我试图访问placemarks 数组上的另一个属性，即addressDictionary，它没有产生预期的结果。

 func getLocationFrom(postalCode: String, callback: @escaping(_ locality: String?) -> Void){


    let geocoder = CLGeocoder()
    geocoder.geocodeAddressString(postalCode) {
        (placemarks, error) -> Void in

       callback(placemarks?[0].locality)

    }
