1、在前台的时候获取地理位置信息
ios 8/9
在info.plist中配置NSLocationWhenInUseUsageDescription的值，否则上面的方法无效
调用.requestWhenInUseAuthorization()获取前台获取地理位置权限
调用.startUpdatingLocation()
代码示例
class ViewController: UIViewController {
lazy var locateM : CLLocationManager = {
let locate = CLLocationManager() locate.delegate = self locate.requestWhenInUseAuthorization() return locate }
() override func touchesBegan(touches: Set<UITouch>, 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:
class ViewController: UIViewController {
lazy var locateM : CLLocationManager = {
let locate = CLLocationManager() locate.delegate = self locate.requestWhenInUseAuthorization() if #available(iOS 9.0, *) {
locate.allowsBackgroundLocationUpdates = true }
return locate }
() override func touchesBegan(touches: Set<UITouch>, 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") }
}
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 ViewController: UIViewController {
lazy var locateM : CLLocationManager = {
let locate = CLLocationManager() locate.delegate = self locate.requestAlwaysAuthorization() if #available(iOS 9.0, *) {
locate.allowsBackgroundLocationUpdates = true }
return locate }
() override func touchesBegan(touches: Set<UITouch>, 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") }
}
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
func locationManager(manager: CLLocationManager, didChangeAuthorizationStatus status: CLAuthorizationStatus) {
switch status {
case .AuthorizedAlways: print("始终") case .AuthorizedWhenInUse: print("使用的时候") case .Denied: print("拒绝") if CLLocationManager.locationServicesEnabled() {
print("真拒绝了") }
else{
print("是关闭了定位服务") }
case .NotDetermined: print("第一次，尚未决定") case .Restricted: 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 = 100 //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
self.locateM.desiredAccuracy = kCLLocationAccuracyBest //kCLLocationAccuracyBestForNavigation //kCLLocationAccuracyBest //kCLLocationAccuracyNearestTenMeters //kCLLocationAccuracyHundredMeters //kCLLocationAccuracyKilometer //kCLLocationAccuracyThreeKilometers
7.CLLocation详解
public var coordinate: CLLocationCoordinate2D {
get }
//经纬度public var altitude: CLLocationDistance {
get }
//海拔public var horizontalAccuracy: CLLocationAccuracy {
get }
//位置信息是否有效，如果为负数，则无效 public var verticalAccuracy: CLLocationAccuracy {
get }
//海拔数据是否有效，如果为负数，则无效 public var course: CLLocationDirection {
get }
//当前的角度(0-359.9)public var speed: CLLocationSpeed {
get }
//当前的速度 public var timestamp: NSDate {
get }
//位置确定的时间戳 public var floor: CLFloor? {
get }
//楼层(前提是已经注册的建筑),如果没有为nil //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
class ViewController: UIViewController {
@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 ViewController: UIViewController {
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() //首先应该判断当前是否可以监听某个区域 if CLLocationManager.isMonitoringAvailableForClass(CLCircularRegion){
//1.创建区域 let center = CLLocationCoordinate2DMake(21.123, 121.345) var distance : CLLocationDistance = 1000 //限制监听的范围不能超过最大的范围 if distance < locateM.maximumRegionMonitoringDistance{
distance = locateM.maximumRegionMonitoringDistance }
let region = CLCircularRegion(center: center, radius: distance, identifier: "xiaoxiao") //2.监听区域 self.locateM.startMonitoringForRegion(region) //3.判断当前状态是否是在区域内还是区域外， //在`didDetermineState`代理方法中获得结果 self.locateM.requestStateForRegion(region) }
}
}
extension ViewController : CLLocationManagerDelegate{
func locationManager(manager: CLLocationManager, didEnterRegion region: CLRegion) {
print("进入了区域"+region.identifier) }
func locationManager(manager: CLLocationManager, didExitRegion region: CLRegion) {
print("出了区域"+region.identifier) }
func locationManager(manager: CLLocationManager, didDetermineState state: CLRegionState, forRegion region: CLRegion) {
//获取刚开始是否在区域内或者区域外 if region.identifier == "xiaoxiao"{
switch state {
case .Inside: print("已经是区域内的") case .Outside: print("没有在区域内") case .Unknown: print("不清楚") }
}
}
}
10、地理编码与反地理编码
地理编码
let geoCoder = CLGeocoder()geoCoder.geocodeAddressString("广州") {
(pls:[CLPlacemark]?, error : NSError?) in if error == nil{
print("地址编码成功") print(pls?.last?.location) }
else{
print("错误 (error)") }
}
打印
地址编码成功
Optional(<+23.12517800,+113.28063700> +/- 100.00m (speed -1.00 mps / course -1.00) @ 8/14/16, 9:49:22 PM China Standard Time)
反地理编码
let geoCoder = CLGeocoder()geoCoder.reverseGeocodeLocation(CLLocation(latitude:23.125,longitude: 113.280)) {
(pls:[CLPlacemark]?, error:NSError?) in if error == nil{
print("地址反编码成功 城市:(pls?.last?.locality)") print(pls?.last?.addressDictionary) }
else{
print("错误 (error)") }
}
打印
地址反编码成功 城市:Optional("Guangzhou")
Optional([SubLocality: Yuexiu, Street: Yunhai Tongjin No.11, State: Guangdong, CountryCode: CN, Thoroughfare: Yunhai Tongjin No.11, Name: Luo Sangmeidi, Country: China, FormattedAddressLines: <__NSArrayM 0x7ff1da5652d0>(Yunhai Tongjin No.11 Yuexiu,Guangzhou,Guangdong China), City: Guangzhou])
注意同一个CLGeocoder对象，不能同时编码与反编码
比如
let geoCoder = CLGeocoder()geoCoder.geocodeAddressString("广州") {
(pls:[CLPlacemark]?, error : NSError?) in ...}
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 public var location: CLLocation? {
get }
//经纬度@NSCopying public var region: CLRegion? {
get }
//所关联的地理区域@available(iOS 9.0, *)@NSCopying public var timeZone: NSTimeZone? {
get }
//时间域public var addressDictionary: [NSObject : AnyObject]? {
get }
//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:CApublic 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
