在swift中使用reverseGeocodeLocation时，如何显示您所在的当前状态

Question

我正在使用这个显示您最近地址的应用程序测试reverseGeocodeLocation。 我已经完成了所有工作，除了显示你所在的当前状态（IL，NY，分机）。 我怎么做？ 这是我目前的代码：

CLGeocoder().reverseGeocodeLocation(userLocation)
    { (placemarks, error) -> Void in

        if error != nil
        {
            println(error)
        }
        else
        {
            let pm = CLPlacemark(placemark: placemarks![0] as CLPlacemark)

            var subThoroughtare:String = ""
            var thoroughfare:String = ""
            var subLocality:String = ""
            var subAdministrativeArea:String = ""
            var postalCode:String = ""
            var country:String = ""

            if pm.subThoroughfare != nil {subThoroughtare = pm.subThoroughfare!}
            if pm.thoroughfare != nil {thoroughfare = pm.thoroughfare!}
            if pm.subLocality != nil {subLocality = pm.subLocality!}
            if pm.subAdministrativeArea != nil {subAdministrativeArea = pm.subAdministrativeArea!}
            if pm.postalCode != nil {postalCode = pm.postalCode!}
            if pm.country != nil {country = pm.country!}
            self.addressLabel.text = "\(subThoroughtare) \(thoroughfare) \n \(subLocality) \n \(postalCode) \n \(country)"
        }
    }

输出是这个（示例位置）：

 County Road 1760 

 79529 
 United States

Answer 1

对于要查看administrativeArea的状态

    let state = pm.administrativeArea;

如果你看一下它所显示的CLPlacemark类的定义..

var administrativeArea: String! { get } // state, eg. CA
