Ios 无法获取状态&；swift中带有CLGeoCoder的zipcode？

我无法使用CLGeocoder获取州和邮政编码。我仅获取位置名称、国家和城市。我在印度使用此代码获取位置。我使用以下代码获取此位置

func getAddressFromLocation(location: CLLocation) {

        CLGeocoder().reverseGeocodeLocation(location, completionHandler: { (placemarks, error) -> Void in
            print(location)
            self.activityIndicator.stopAnimating()
            if error != nil {
                DILog.print(items: "Reverse geocoder failed with error" + (error.debugDescription))
                return
            }

            var placeMark: CLPlacemark!
            placeMark = placemarks?[0]

            if placeMark == nil {
                return
            }

            // Location name
            if let locationName = placeMark.addressDictionary!["Name"] as? String {
                self.currentLocation = self.currentLocation + locationName
            }

            // Street address
            if let street = placeMark.addressDictionary!["Thoroughfare"] as? String {
                self.currentLocation = self.currentLocation + ", " + street
                self.spotLocation.street_address_1 = street

            }

            // City
            if let city = placeMark.addressDictionary!["City"] as? String {
                print(city, terminator: "")
                self.currentLocation = self.currentLocation + ", " + city
                self.spotLocation.city = city
            }

            // Country
            if let country = placeMark.addressDictionary!["Country"] as? String {
                print(country, terminator: "")
                self.currentLocation = self.currentLocation + ", " + country
                self.spotLocation.country = country

            }
            // Street address
            if let street1 = placeMark.addressDictionary!["SubThoroughfare"] as? String {
                self.currentLocation = self.currentLocation + ", " + street1
                self.spotLocation.street_address_1 = street1


            }
            // state
            if let state = placeMark.addressDictionary!["State"] as? String {
                self.currentLocation = self.currentLocation + ", " + state
                self.spotLocation.state = state
            }
            // Zip
            if let zip = placeMark.addressDictionary!["Zip"] as? String {
                self.currentLocation = self.currentLocation + ", " + zip
                self.spotLocation.state = zip
            }
            self.locationLabel.text? = self.currentLocation


        })

    }

请告诉我如何获得它的解决方案？

您是否打印了

地址字典
以查看它包含的内容？为什么将
placeMark
声明为隐式展开可选？如果可选（！）数组
placemarks
不是
nil
，并且它包含一个项，则该项肯定是非可选的。但是，如果数组为空，您的代码将崩溃。我添加了检查placemark是否为零，然后返回
placemark
将永远不会为
nil
如果
placemarks？[0]
成功。但是，如果数组为空，代码将在
placemarks？[0]
行崩溃。检查
nil
（以及IUO声明）是没有意义的。我将在那里添加检查。感谢您的重要评论。现在您能告诉我我可以再次获取zipcode和state吗：您是否
打印
地址字典
以查看它包含的内容。它是否包含
State
和
Zip
键？如果是，值是什么类型的？
let zipCode = placeMark.postalCode ?? "unknown"
