 lazy var locateM : CLLocationManager = {   let locate = CLLocationManager()   locate.delegate = self   locate.requestWhenInUseAuthorization()   return locate  }()  override func touchesBegan(touches: Set , withEvent event: UIEvent?) {   self.locateM.startUpdatingLocation()  } } extension ViewController : CLLocationManagerDelegate{  func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {   print(“位置信息已经更新”)  } }

2、前后台获取，但是后台获取的时候，屏幕上方有蓝框提示用户正在后台获取

ios8

调用.requestWhenInUseAuthorization()获取前台获取地理位置权限

在info.plist中配置NSLocationWhenInUseUsageDescription的值，否则上面的方法无效

设置Capabilities>BackgroundModes>Location Updates 打对勾

调用.startUpdatingLocation()

ios9

调用.requestWhenInUseAuthorization()获取前台获取地理位置权限

设置 .allowsBackgroundLocationUpdates = true (ios 9需要执行)

在info.plist中配置NSLocationWhenInUseUsageDescription的值，否则上面的方法无效

设置Capabilities>BackgroundModes>Location Updates 打对勾 (如果第二步做了，此步没做，直接crash)

调用.startUpdatingLocation()

ios8/ios9可以后台蓝框定位的代码示例:

讯享网class&nbsp;ViewController:&nbsp;UIViewController&nbsp;{ &nbsp;lazy&nbsp;var&nbsp;locateM&nbsp;:&nbsp;CLLocationManager&nbsp;=&nbsp;{ &nbsp;&nbsp;let&nbsp;locate&nbsp;=&nbsp;CLLocationManager() &nbsp;&nbsp;locate.delegate&nbsp;=&nbsp;self &nbsp;&nbsp;locate.requestWhenInUseAuthorization() &nbsp;&nbsp;if&nbsp;#available(iOS&nbsp;9.0,&nbsp;*)&nbsp;{ &nbsp;&nbsp;&nbsp;locate.allowsBackgroundLocationUpdates&nbsp;=&nbsp;true &nbsp;&nbsp;} &nbsp;&nbsp;return&nbsp;locate &nbsp;}() &nbsp;override&nbsp;func&nbsp;touchesBegan(touches:&nbsp;Set 
   
   
    
     
    
     ,&nbsp;withEvent&nbsp;event:&nbsp;UIEvent?)&nbsp;{

  self.locateM.startUpdatingLocation()  } } extension ViewController : CLLocationManagerDelegate{  func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {   print(“位置信息已经更新”)  } }

3、后台获取，后台获取的时候，屏幕上方无蓝框提示

调用.requestAlwaysAuthorization()获取前台获取地理位置权限

在info.plist中配置NSLocationAlwaysUsageDescription的值，否则上面的方法无效

设置 .allowsBackgroundLocationUpdates = true (ios 9需要执行)

设置Capabilities>BackgroundModes>Location Updates 打对勾 (本步骤在ios 8中可以不做设置，但是在ios9中如果第三步做了，而此步没有做，直接crash)

调用.startUpdatingLocation()

代码示例

class&nbsp;ViewController:&nbsp;UIViewController&nbsp;{ &nbsp;lazy&nbsp;var&nbsp;locateM&nbsp;:&nbsp;CLLocationManager&nbsp;=&nbsp;{ &nbsp;&nbsp;let&nbsp;locate&nbsp;=&nbsp;CLLocationManager() &nbsp;&nbsp;locate.delegate&nbsp;=&nbsp;self &nbsp;&nbsp;locate.requestAlwaysAuthorization() &nbsp;&nbsp;if&nbsp;#available(iOS&nbsp;9.0,&nbsp;*)&nbsp;{ &nbsp;&nbsp;&nbsp;locate.allowsBackgroundLocationUpdates&nbsp;=&nbsp;true &nbsp;&nbsp;} &nbsp;&nbsp;return&nbsp;locate &nbsp;}() &nbsp;override&nbsp;func&nbsp;touchesBegan(touches:&nbsp;Set 
  
   
    
     
    
    ,&nbsp;withEvent&nbsp;event:&nbsp;UIEvent?)&nbsp;{

4、权限改变的通知

注意：在Denied或者NotDetermined的状态下startUpdatingLocation,开始监听之后,当状态改变成允许的状态时，会直接进入监听状态，不必再次调用startUpdateingLocation

讯享网func&nbsp;locationManager(manager:&nbsp;CLLocationManager,&nbsp;didChangeAuthorizationStatus&nbsp;status:&nbsp;CLAuthorizationStatus)&nbsp;{ &nbsp;&nbsp;switch&nbsp;status&nbsp;{ &nbsp;&nbsp;case&nbsp;.AuthorizedAlways: &nbsp;&nbsp;&nbsp;print(“始终”) &nbsp;&nbsp;case&nbsp;.AuthorizedWhenInUse: &nbsp;&nbsp;&nbsp;print(“使用的时候”) &nbsp;&nbsp;case&nbsp;.Denied: &nbsp;&nbsp;&nbsp;print(“拒绝”) &nbsp;&nbsp;&nbsp;if&nbsp;CLLocationManager.locationServicesEnabled()&nbsp;{ &nbsp;&nbsp;&nbsp;&nbsp;print(“真拒绝了”) &nbsp;&nbsp;&nbsp;}else{ &nbsp;&nbsp;&nbsp;&nbsp;print(“是关闭了定位服务”) &nbsp;&nbsp;&nbsp;} &nbsp;&nbsp;case&nbsp;.NotDetermined: &nbsp;&nbsp;&nbsp;print(“第一次，尚未决定”) &nbsp;&nbsp;case&nbsp;.Restricted: &nbsp;&nbsp;&nbsp;print(“没有权限的”)

  }  }

5、过滤距离

很多时候我们需要监听函数只调用一次来获取用户当前的位置

在监听函数中停止监听

设置监听的过滤距离

//如果监听器已经开启,此值修改之后立即生效 self.locateM.distanceFilter&nbsp;=&nbsp;100&nbsp;//每100米，调用一次监听

6、精度

注意：越精确越耗电,定位的时间越长，如果要定位城市，没有必要选最精确的

讯享网self.locateM.desiredAccuracy&nbsp;=&nbsp;kCLLocationAccuracyBest &nbsp;//kCLLocationAccuracyBestForNavigation &nbsp;//kCLLocationAccuracyBest &nbsp;//kCLLocationAccuracyNearestTenMeters &nbsp;//kCLLocationAccuracyHundredMeters &nbsp;//kCLLocationAccuracyKilometer &nbsp;//kCLLocationAccuracyThreeKilometers

7.CLLocation详解

public&nbsp;var&nbsp;coordinate:&nbsp;CLLocationCoordinate2D&nbsp;{&nbsp;get&nbsp;}&nbsp;&nbsp;//经纬度 public&nbsp;var&nbsp;altitude:&nbsp;CLLocationDistance&nbsp;{&nbsp;get&nbsp;}&nbsp;&nbsp;&nbsp;//海拔 public&nbsp;var&nbsp;horizontalAccuracy:&nbsp;CLLocationAccuracy&nbsp;{&nbsp;get&nbsp;}&nbsp;//位置信息是否有效，如果为负数，则无效&nbsp; public&nbsp;var&nbsp;verticalAccuracy:&nbsp;CLLocationAccuracy&nbsp;{&nbsp;get&nbsp;}&nbsp;//海拔数据是否有效，如果为负数，则无效&nbsp; public&nbsp;var&nbsp;course:&nbsp;CLLocationDirection&nbsp;{&nbsp;get&nbsp;}&nbsp;&nbsp;&nbsp;//当前的角度(0-359.9) public&nbsp;var&nbsp;speed:&nbsp;CLLocationSpeed&nbsp;{&nbsp;get&nbsp;}&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;//当前的速度&nbsp;&nbsp; public&nbsp;var&nbsp;timestamp:&nbsp;NSDate&nbsp;{&nbsp;get&nbsp;}&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;//位置确定的时间戳&nbsp;&nbsp; public&nbsp;var&nbsp;floor:&nbsp;CLFloor?&nbsp;{&nbsp;get&nbsp;}&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;//楼层(前提是已经注册的建筑),如果没有为nil&nbsp;&nbsp;

//计算两个经纬度之间的距离   public func distanceFromLocation(location: CLLocation) -> CLLocationDistance

8、指南针小例子

讯享网class&nbsp;ViewController:&nbsp;UIViewController&nbsp;{

 @IBOutlet weak var mImageView: UIImageView!  lazy var locateM : CLLocationManager = {   let locate = CLLocationManager()   locate.delegate = self   locate.requestAlwaysAuthorization()   if #available(iOS 9.0, ) {    locate.allowsBackgroundLocationUpdates = true   }   return locate  }()  override func viewDidLoad() {   super.viewDidLoad()   if(CLLocationManager.headingAvailable()){    self.locateM.startUpdatingHeading()   }else{    print(“当前磁力计有问题”)   }   } } extension ViewController : CLLocationManagerDelegate{  func locationManager(manager: CLLocationManager, didUpdateHeading newHeading: CLHeading) {   //1.拿到当前设备对正朝向的角度   let angle = newHeading.magneticHeading   //2.把角度转换成弧度   let hudu = CGFloat(angle / 180  M_PI)   //3.反向旋转照片   UIView.animateWithDuration(0.5) {     self.mImageView.transform = CGAffineTransformMakeRotation(-hudu)   }  } }

9、区域的监听

class&nbsp;ViewController:&nbsp;UIViewController&nbsp;{ &nbsp;lazy&nbsp;var&nbsp;locateM&nbsp;:&nbsp;CLLocationManager&nbsp;=&nbsp;{ &nbsp;&nbsp;let&nbsp;locate&nbsp;=&nbsp;CLLocationManager() &nbsp;&nbsp;locate.delegate&nbsp;=&nbsp;self &nbsp;&nbsp;locate.requestAlwaysAuthorization() &nbsp;&nbsp;if&nbsp;#available(iOS&nbsp;9.0,&nbsp;*)&nbsp;{ &nbsp;&nbsp;&nbsp;locate.allowsBackgroundLocationUpdates&nbsp;=&nbsp;true &nbsp;&nbsp;} &nbsp;&nbsp;return&nbsp;locate &nbsp;}() &nbsp;override&nbsp;func&nbsp;viewDidLoad()&nbsp;{ &nbsp;&nbsp;super.viewDidLoad() &nbsp;&nbsp;//首先应该判断当前是否可以监听某个区域 &nbsp;&nbsp;if&nbsp;CLLocationManager.isMonitoringAvailableForClass(CLCircularRegion){ &nbsp;&nbsp;&nbsp;//1.创建区域 &nbsp;&nbsp;&nbsp;let&nbsp;center&nbsp;=&nbsp;CLLocationCoordinate2DMake(21.123,&nbsp;121.345) &nbsp;&nbsp;&nbsp;var&nbsp;distance&nbsp;:&nbsp;CLLocationDistance&nbsp;=&nbsp;1000 &nbsp;&nbsp;&nbsp;//限制监听的范围不能超过最大的范围 &nbsp;&nbsp;&nbsp;if&nbsp;distance&nbsp;<&nbsp;locateM.maximumRegionMonitoringDistance{ &nbsp;&nbsp;&nbsp;&nbsp;distance&nbsp;=&nbsp;locateM.maximumRegionMonitoringDistance &nbsp;&nbsp;&nbsp;} &nbsp;&nbsp;&nbsp;let&nbsp;region&nbsp;=&nbsp;CLCircularRegion(center:&nbsp;center,&nbsp;radius:&nbsp;distance,&nbsp;identifier:&nbsp;“xiaoxiao”) &nbsp;&nbsp;&nbsp;//2.监听区域 &nbsp;&nbsp;&nbsp;self.locateM.startMonitoringForRegion(region) &nbsp;&nbsp;&nbsp;//3.判断当前状态是否是在区域内还是区域外， &nbsp;&nbsp;&nbsp;//在didDetermineState代理方法中获得结果 &nbsp;&nbsp;&nbsp;self.locateM.requestStateForRegion(region) &nbsp;&nbsp;} &nbsp;} } extension&nbsp;ViewController&nbsp;:&nbsp;CLLocationManagerDelegate{ &nbsp;func&nbsp;locationManager(manager:&nbsp;CLLocationManager,&nbsp;didEnterRegion&nbsp;region:&nbsp;CLRegion)&nbsp;{ &nbsp;&nbsp;print(“进入了区域”+region.identifier) &nbsp;} &nbsp;func&nbsp;locationManager(manager:&nbsp;CLLocationManager,&nbsp;didExitRegion&nbsp;region:&nbsp;CLRegion)&nbsp;{ &nbsp;&nbsp;print(“出了区域”+region.identifier) &nbsp;} &nbsp;func&nbsp;locationManager(manager:&nbsp;CLLocationManager,&nbsp;didDetermineState&nbsp;state:&nbsp;CLRegionState,&nbsp;forRegion&nbsp;region:&nbsp;CLRegion)&nbsp;{ &nbsp;&nbsp;//获取刚开始是否在区域内或者区域外 &nbsp;&nbsp;if&nbsp;region.identifier&nbsp;==&nbsp;“xiaoxiao”{ &nbsp;&nbsp;&nbsp;switch&nbsp;state&nbsp;{ &nbsp;&nbsp;&nbsp;case&nbsp;.Inside: &nbsp;&nbsp;&nbsp;&nbsp;print(“已经是区域内的”) &nbsp;&nbsp;&nbsp;case&nbsp;.Outside: &nbsp;&nbsp;&nbsp;&nbsp;print(“没有在区域内”) &nbsp;&nbsp;&nbsp;case&nbsp;.Unknown: &nbsp;&nbsp;&nbsp;&nbsp;print(“不清楚”) &nbsp;&nbsp;&nbsp;} &nbsp;&nbsp;} &nbsp;} }

10、地理编码与反地理编码

地理编码

讯享网let&nbsp;geoCoder&nbsp;=&nbsp;CLGeocoder() geoCoder.geocodeAddressString(“广州”)&nbsp;{&nbsp;(pls:[CLPlacemark]?,&nbsp;error&nbsp;:&nbsp;NSError?)&nbsp;in &nbsp;if&nbsp;error&nbsp;==&nbsp;nil{ &nbsp;&nbsp;print(“地址编码成功”) &nbsp;&nbsp;print(pls?.last?.location) &nbsp;}else{ &nbsp;&nbsp;print(“错误&nbsp;(error)”) &nbsp;}&nbsp;&nbsp; }

打印

地址编码成功

Optional(<+23.,+113.>&nbsp;+/-&nbsp;100.00m&nbsp;(speed&nbsp;-1.00&nbsp;mps&nbsp;/&nbsp;course&nbsp;-1.00)&nbsp;@&nbsp;8/14/16,&nbsp;9:49:22&nbsp;PM&nbsp;China&nbsp;Standard&nbsp;Time)

反地理编码

讯享网let&nbsp;geoCoder&nbsp;=&nbsp;CLGeocoder() geoCoder.reverseGeocodeLocation(CLLocation(latitude:23.125,longitude:&nbsp;113.280))&nbsp;{&nbsp;(pls:[CLPlacemark]?,&nbsp;error:NSError?)&nbsp;in &nbsp;&nbsp;&nbsp;if&nbsp;error&nbsp;==&nbsp;nil{ &nbsp;&nbsp;&nbsp;&nbsp;print(“地址反编码成功&nbsp;城市:(pls?.last?.locality)”) &nbsp;&nbsp;&nbsp;&nbsp;print(pls?.last?.addressDictionary) &nbsp;&nbsp;&nbsp;}else{ &nbsp;&nbsp;&nbsp;&nbsp;print(“错误&nbsp;(error)”) &nbsp;&nbsp;&nbsp;} &nbsp;&nbsp;}

打印

地址反编码成功城市:Optional(“Guangzhou”)

Optional([SubLocality:&nbsp;Yuexiu,&nbsp;Street:&nbsp;Yunhai&nbsp;Tongjin&nbsp;No.11,&nbsp;State:&nbsp;Guangdong,&nbsp;CountryCode:&nbsp;CN,&nbsp;Thoroughfare:&nbsp;Yunhai&nbsp;Tongjin&nbsp;No.11,&nbsp;Name:&nbsp;Luo&nbsp;Sangmeidi,&nbsp;Country:&nbsp;China,&nbsp;FormattedAddressLines:&nbsp;<__NSArrayM&nbsp;0x7ff1da5652d0>( Yunhai&nbsp;Tongjin&nbsp;No.11&nbsp;Yuexiu, Guangzhou, Guangdong&nbsp;China ) ,&nbsp;City:&nbsp;Guangzhou])

注意同一个CLGeocoder对象，不能同时编码与反编码

比如

讯享网let&nbsp;geoCoder&nbsp;=&nbsp;CLGeocoder() geoCoder.geocodeAddressString(“广州”)&nbsp;{&nbsp;(pls:[CLPlacemark]?,&nbsp;error&nbsp;:&nbsp;NSError?)&nbsp;in &nbsp;…

} geoCoder.reverseGeocodeLocation(CLLocation(latitude:23.125,longitude: 113.280)) { (pls:[CLPlacemark]?, error:NSError?) in  …  }

这样只会打印第一个编码成功的结果

11、CLPlacemark对象详解

@NSCopying&nbsp;public&nbsp;var&nbsp;location:&nbsp;CLLocation?&nbsp;{&nbsp;get&nbsp;}&nbsp;&nbsp;&nbsp;&nbsp;//经纬度 @NSCopying&nbsp;public&nbsp;var&nbsp;region:&nbsp;CLRegion?&nbsp;{&nbsp;get&nbsp;}&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;//所关联的地理区域 @available(iOS&nbsp;9.0,&nbsp;*) @NSCopying&nbsp;public&nbsp;var&nbsp;timeZone:&nbsp;NSTimeZone?&nbsp;{&nbsp;get&nbsp;}&nbsp;&nbsp;&nbsp;&nbsp;//时间域 public&nbsp;var&nbsp;addressDictionary:&nbsp;[NSObject&nbsp;:&nbsp;AnyObject]?&nbsp;{&nbsp;get&nbsp;}&nbsp;//详细地址信息

//addressDictionary中的属性 public var name: String? { get }     //名字  public var thoroughfare: String? { get }   //街道名字 public var subThoroughfare: String? { get }  //子街道名字 public var locality: String? { get }    //城市名称 public var subLocality: String? { get }   //邻城市名称 public var administrativeArea: String? { get }  //行政区域 比如:CA public var subAdministrativeArea: String? { get } //子行政区域 public var postalCode: String? { get }    //邮政编码 public var ISOcountryCode: String? { get }   //国家代码表 public var country: String? { get }    //国家 public var inlandWater: String? { get }   //内陆水域 public var ocean: String? { get }     //海洋 public var areasOfInterest: [String]? { get }  //兴趣点
