ios - 地址转换成坐标

Question

我正在使用以下代码，该代码失败并且未进入内部函数。

geocoder.geocodeAddressString(location, completionHandler: {(placemarks: [CLPlacemark]?, error: NSError?) -> Void in //Fails here

        let placemark = placemarks?.first
        let lat = placemark?.location?.coordinate.latitude
        let lon = placemark?.location?.coordinate.longitude
        print("Lat: \(lat), Lon: \(lon)")
    } as! CLGeocodeCompletionHandler )

请帮忙!预先感谢:-)

您使用了错误的语法，Swift 3 中没有参数标签，并且 NSError 已替换为 Error:

geocoder.geocodeAddressString(location) { (placemarks, error) in 

    if let placemark = placemarks?.first, let location = placemark.location {
       let lat = location.coordinate.latitude
       let lon = location.coordinate.longitude
       print("Lat: \(lat), Lon: \(lon)")
    }
}
