Swift-longitude and latitude position coordinates transform with real geographic location

Through the Corelocation class, the location information obtained is the geographical information expressed in longitude and latitude, and can be deserialized into an address by the Clgeocoder class. Conversely, latitude and longitude can also be obtained according to an address.

1, get address by latitude

[CLPlacemark]            if pm.count > 0{                p = placemarks[0] as? CLPlacemark                //println(p) //输出反编码信息                self.textView.text = p?.name            } else {                println("No placemarks!")            }        })    }    override func didReceiveMemoryWarning() {        super.didReceiveMemoryWarning()    }}

2, get latitude and longitude by address

[CLPlacemark]            if pm.count > 0{                p = placemarks[0] as! CLPlacemark                self.textView.text = "经度：\(p.location.coordinate.longitude)   "                    + "纬度：\(p.location.coordinate.latitude)"            } else {                println("No placemarks!")            }        })    }    override func didReceiveMemoryWarning() {        super.didReceiveMemoryWarning()    }}
