string - 从 CLPlacemark 创建地址字符串

Question

谁能建议清洁工从 CLPlacemark 创建地址字符串。

目前我正在使用这个扩展

extension CLPlacemark {

    func makeAddressString() -> String {
        var address = ""
        if subThoroughfare != nil { address = address + " " + subThoroughfare! }
        if thoroughfare != nil { address = address + " " + thoroughfare! }
        if locality != nil { address = address + " " + locality! }
        if administrativeArea != nil { address = address + " " + administrativeArea! }
        if postalCode != nil { address = address + " " + postalCode! }
        if country != nil { address = address + " " + country! }
        return address
    }
}

所有实例变量都是可选的，因此检查是否为 nil，我希望街道编号、街道等的顺序相同。

CLPlacemark 具有 CNPostalAddress 类型的 postalAddress 属性。您可以使用 CNPostalAddressFormatter 将其格式化为区域设置感知 字符串。

let formatter = CNPostalAddressFormatter()
let addressString = formatter.string(from: placemark.postalAddress)
