定位服务编程
(一)、地理信息反编码（需要框架CoreLocation，主要使用类 CLLocationManagerDelegate／CLLocationManager／CLLocation／CLPlacemark）其中 CLPlacemark 地标类属性有国家信息，指定城市信息，街道级别信息等

// NSLocationAlwaysUsageDescription ＝ yes
self.locationManager.requestAlwaysAuthorization()// 前后台同时定位
}
// Do any additional setup after loading the view, typically from a nib.
}
// 地理信息反编码
@IBAction func clickButton(sender: UIButton) {
let geocoder = CLGeocoder() //实例化 CLGeocoder地理反编码对象
// 调用地理反编码对象的reverseGeocodeLocation

//给点地名，定位坐标 CLGeocoder geocodeAddressString方法

// ServiceAndMap

//
import UIKit
import CoreLocation
class SelWhereViewController: UIViewController,CLLocationManagerDelegate{
var locationManager:CLLocationManager!
@IBOutlet weak var selText: UITextField!
@IBOutlet weak var textView: UITextView!
@IBAction func selClick(sender: AnyObject) {
//查询地点为空时不执行
if selText.text == nil || NSString(string: selText.text!).length == 0 {
return
}
// 地理信息编码查询，查询的返回结果marks参数是NSArray类型集合
CLGeocoder().geocodeAddressString(self.selText.text!) { (marks:[CLPlacemark]?, error:NSError?) in
print("查询纪录数：\(marks)")
if marks?.count > 0 {
// 取出第一个参数 ，其中CLPlacemark封装了街道，区域等信息
let placemark = marks![0]
// 获得地标的经纬度信息
let coordinate = placemark.location?.coordinate
let strCoordinater = NSString(format: "经度:\(coordinate!.longitude)\n纬度:\(coordinate!.latitude)")
self.textView.text = NSString(format: "\(strCoordinater) \n \(placemark.country!) \n\(placemark.locality!) \n \((placemark.thoroughfare == nil ? "" : placemark.thoroughfare)!)", locale: nil) as String
// 关闭键盘，如果想输入中文字 先在模拟器中找到设置，
// 即Settings->General->Keyboard->Keyboards->Add New Keyboard...
// 到了这里大家应该就都明白了，在列表中选择自己需要的输入法，
// 我选择的中文输入法是Chinese-Simplified(PinYin)即简体拼音其它没有试过
self.selText.resignFirstResponder()
}
}
}
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
/*
// MARK: - Navigation
// In a storyboard-based application, you will often want to do a little preparation before navigation
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
// Get the new view controller using segue.destinationViewController.
// Pass the selected object to the new view controller.
}
*/
}
（三）、定位服务测试
Scheme ——> Eidt Scheme ——> Options ——> Defual location
如果地名没有添加gpx文件
工具 www.mygeoposition.com生成gpx文件
（四）、使用苹果地图（MapKit框架，mapview控件）
添加标柱：（第一步：触发添加动作，第二步：实现地图委托方法）
//
// IOSMapViewController.swift
// ServiceAndMap
//
// Created by sus001 on 16/6/10.
// Copyright © 2016年 njsus. All rights reserved.
//
import UIKit
import MapKit
class IOSMapViewController: UIViewController,MKMapViewDelegate{
@IBOutlet weak var mapView: MKMapView!
@IBOutlet weak var selText: UITextField!
// 添加标柱：（第一步：触发添加动作，第二步：实现地图委托方法）
@IBAction func selClic(sender: AnyObject) {
if self.selText.text == nil || NSString(string: self.selText.text!).length == 0 {
return
}
let gecoder = CLGeocoder()
gecoder.geocodeAddressString(self.selText.text!) { (placemarks:[CLPlacemark]?, error:NSError?) in
NSLog("查询记录：\(placemarks!.count)")
if placemarks?.count > 0 {
self.mapView.removeAnnotations(self.mapView.annotations)
}
var i = 0
repeat{
self.selText.resignFirstResponder() //关闭键盘
let placemark = placemarks![i]
// 调整地图位置和缩放比例
// 第一个参数：指定区域的中心点，第二个参数 是南北跨度，第三个参数是东西跨度，这个两个参数会影响地图缩放
let viewRegion = MKCoordinateRegionMakeWithDistance((placemark.location!.coordinate), 100000, 100000)
// 重新设置地图的显示区域
self.mapView.setRegion(viewRegion, animated: true)
// 实例化 MKAnnotation子类对象，这个是自定义的类为地图上标注
// 地图上的标注点是MKPinAnnotationView（大头针标注视图）类型，这个视图要求标注点信息由实现MKAnnotation协议的类提供
let annotation = MapLocation(coordinate: (placemark.location?.coordinate)!)
annotation.name = placemark.name
// annotation.streetAdress = placemark.subThoroughfare
// annotation.city = placemark.locality
// annotation.state = placemark.administrativeArea
// annotation.zip = placemark.postalCode
// 将标注点对象添加到地图上 ，一旦调用这个方法，地图视图委托方法就会被调用 mapView:viewForAnnotation: self.mapView.addAnnotation(annotation)
i = i + 1
}while(i < placemarks!.count)
// for var i = 0;i < placemarks!.count;i=(i+1) {
// self.selText.resignFirstResponder() //关闭键盘
// let placemark = placemarks![i]
// // 调整地图位置和缩放比例
// let viewRegion = MKCoordinateRegionMakeWithDistance((placemark.location!.coordinate), 10000, 10000)
// self.mapView.setRegion(viewRegion, animated: true)
//
//
// let annotation = MapLocation(coordinate: (placemark.location?.coordinate)!)
//
// annotation.streetAdress = placemark.thoroughfare
// annotation.city = placemark.locality
// annotation.state = placemark.administrativeArea
// annotation.zip = placemark.postalCode
// self.mapView.addAnnotation(annotation)
// print("placemarks!.count:\(placemarks!.count)")
// }
if error != nil {
print(error?.localizedDescription)
}
}
}
// 这个方法在地图视图添加标注时回调 mapView.addAnnotation(annotation) annotation地图标注对象
func mapView(mapView: MKMapView, viewForAnnotation annotation: MKAnnotation) -> MKAnnotationView? {
// 用于获得地图标注对象 MKPinAnnotationView
var annotationView = self.mapView.dequeueReusableAnnotationViewWithIdentifier("dd") as? MKPinAnnotationView
if annotationView == nil {
annotationView = MKPinAnnotationView(annotation: annotation, reuseIdentifier: "dd")
}
// 设置大头针标注视图的颜色为紫色（红色／绿色）
annotationView?.pinTintColor = UIColor.purpleColor()
// 设置标注视图时，是否以动画效果的信息显示在地图上
annotationView?.animatesDrop = true
// 用于在标注点上显示一些附加信息 （大点的文字保存在Title属性中小的文字保存中subTitle属性中）
annotationView?.canShowCallout = true
return annotationView
}
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
if CLLocationManager.locationServicesEnabled() == true {
mapView.mapType = MKMapType.Standard
mapView.delegate = self
// 跟踪用户位置变化
self.mapView.showsUserLocation = true
self.mapView.setUserTrackingMode(.Follow, animated: true)
}
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
/*
// MARK: - Navigation
// In a storyboard-based application, you will often want to do a little preparation before navigation
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
// Get the new view controller using segue.destinationViewController.
// Pass the selected object to the new view controller.
}
*/
}
（五）、使用程序外地图（调用ios苹果地图）
// MapOutViewController.swift
// ServiceAndMap
//
// Created by sus001 on 16/6/11.
// Copyright © 2016年 njsus. All rights reserved.
//
import UIKit
import CoreLocation
import MapKit
class MapOutViewController: UIViewController{
@IBOutlet weak var selTxt: UITextField!
@IBAction func selClick(sender: AnyObject) {
if self.selTxt.text == nil || NSString(string: self.selTxt.text!).length == 0 {
return
}
// 调用IOS苹果地图
CLGeocoder().geocodeAddressString(self.selTxt.text!) { (placemarks:[CLPlacemark]?, error:NSError?) in
print("查询记录数:\(placemarks?.count)")
// 多个点需要标注,起点默认是当前位置，通过定位服务获得
var arrary = [MKMapItem]()
var i = 0
repeat{
// 实例化MKPlacemark对象 CLPlacemark 是地图上的地标类 MKPlacemark 定位是一的地标类
let place = MKPlacemark(placemark: placemarks![i])
let mapItem = MKMapItem(placemark: place)
arrary.append(mapItem)
i = i + 1
}while(i < placemarks?.count)
self.selTxt.resignFirstResponder()
if arrary.count > 0 {
MKMapItem.openMapsWithItems(arrary, launchOptions: nil)
}
/*
// 单个点标注
if placemarks?.count > 0 {
let mark = placemarks![0]
// let coordinate = mark.location?.coordinate
// 实例化MKPlacemark对象 CLPlacemark 是地图上的地标类 MKPlacemark 定位是一的地标类
// let place = MKPlacemark(coordinate: (mark.location?.coordinate)!, addressDictionary: mark.addressDictionary as![String : AnyObject]?)
// let mapItem = MKMapItem(placemark: place)
let mkplacemark = MKPlacemark(placemark: mark)
// 实例化MKMapItem对象，封装类地图上一个点的信息类
let mapItem = MKMapItem(placemark: mkplacemark)
// 调用ios自动的苹果地图应用
// openInMapsWithLaunchOptions：是MKMapItem 类的实例方法 ，
// 参数是控制显示地图的初始化信息（设定路线模式／设定地图类型MKLaunchOptionsMapTypeKey／设定丢图中心点／设置地图跨度／设置显示交通状况）
mapItem.openInMapsWithLaunchOptions(nil)
self.selTxt.resignFirstResponder()
}
*/
}
}
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
