1、在前臺的時候獲取地理位置信息
ios 8/9
在info.plist中配置NSLocationWhenInUseUsageDescription的值，否則上面的方法無效
調用.requestWhenInUseAuthorization()獲取前臺獲取地理位置權限
調用.startUpdatingLocation()
代碼示例
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("位置信息已經更新") }}2、前后臺獲取，但是后臺獲取的時候，屏幕上方有藍框提示用戶正在后臺獲取
ios8
調用.requestWhenInUseAuthorization()獲取前臺獲取地理位置權限
在info.plist中配置NSLocationWhenInUseUsageDescription的值，否則上面的方法無效
設置Capabilities>BackgroundModes>Location Updates 打對勾
調用.startUpdatingLocation()
ios9
調用.requestWhenInUseAuthorization()獲取前臺獲取地理位置權限
設置 .allowsBackgroundLocationUpdates = true (ios 9需要執行)
在info.plist中配置NSLocationWhenInUseUsageDescription的值，否則上面的方法無效
設置Capabilities>BackgroundModes>Location Updates 打對勾 (如果第二步做了，此步沒做，直接crash)
調用.startUpdatingLocation()
ios8/ios9可以后臺藍框定位的代碼示例:
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("位置信息已經更新") }}3、后臺獲取，后臺獲取的時候，屏幕上方無藍框提示
調用.requestAlwaysAuthorization()獲取前臺獲取地理位置權限
在info.plist中配置NSLocationAlwaysUsageDescription的值，否則上面的方法無效
設置 .allowsBackgroundLocationUpdates = true (ios 9需要執行)
設置Capabilities>BackgroundModes>Location Updates 打對勾 (本步驟在ios 8中可以不做設置，但是在ios9中如果第三步做了，而此步沒有做，直接crash)
調用.startUpdatingLocation()
代碼示例
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("位置信息已經更新") }}4、權限改變的通知
注意：在Denied或者NotDetermined的狀態下startUpdatingLocation,開始監聽之后,當狀態改變成允許的狀態時，會直接進入監聽狀態，不必再次調用startUpdateingLocation
func locationManager(manager: CLLocationManager, didChangeAuthorizationStatus status: CLAuthorizationStatus) { switch status { case .AuthorizedAlways: print("始終") case .AuthorizedWhenInUse: print("使用的時候") case .Denied: print("拒絕") if CLLocationManager.locationServicesEnabled() { print("真拒絕了") }else{ print("是關閉了定位服務") } case .NotDetermined: print("第一次，尚未決定") case .Restricted: print("沒有權限的") } }5、過濾距離
很多時候我們需要監聽函數只調用一次來獲取用戶當前的位置
在監聽函數中停止監聽
設置監聽的過濾距離
//如果監聽器已經開啟,此值修改之后立即生效self.locateM.distanceFilter = 100 //每100米，調用一次監聽
6、精度
注意：越精確越耗電,定位的時間越長，如果要定位城市，沒有必要選最精確的
self.locateM.desiredAccuracy = kCLLocationAccuracyBest //kCLLocationAccuracyBestForNavigation //kCLLocationAccuracyBest //kCLLocationAccuracyNearestTenMeters //kCLLocationAccuracyHundredMeters //kCLLocationAccuracyKilometer //kCLLocationAccuracyThreeKilometers
7.CLLocation詳解
public var coordinate: CLLocationCoordinate2D { get } //經緯度public var altitude: CLLocationDistance { get } //海拔public var horizontalAccuracy: CLLocationAccuracy { get } //位置信息是否有效，如果為負數，則無效 public var verticalAccuracy: CLLocationAccuracy { get } //海拔數據是否有效，如果為負數，則無效 public var course: CLLocationDirection { get } //當前的角度(0-359.9)public var speed: CLLocationSpeed { get } //當前的速度 public var timestamp: NSDate { get } //位置確定的時間戳 public var floor: CLFloor? { get } //樓層(前提是已經注冊的建筑),如果沒有為nil //計算兩個經緯度之間的距離 public func distanceFromLocation(location: CLLocation) -> CLLocationDistance8、指南針小例子
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("當前磁力計有問題") } }}extension ViewController : CLLocationManagerDelegate{ func locationManager(manager: CLLocationManager, didUpdateHeading newHeading: CLHeading) { //1.拿到當前設備對正朝向的角度 let angle = newHeading.magneticHeading //2.把角度轉換成弧度 let hudu = CGFloat(angle / 180 * M_PI) //3.反向旋轉照片 UIView.animateWithDuration(0.5) { self.mImageView.transform = CGAffineTransformMakeRotation(-hudu) } }}9、區域的監聽
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() //首先應該判斷當前是否可以監聽某個區域 if CLLocationManager.isMonitoringAvailableForClass(CLCircularRegion){ //1.創建區域 let center = CLLocationCoordinate2DMake(21.123, 121.345) var distance : CLLocationDistance = 1000 //限制監聽的范圍不能超過最大的范圍 if distance < locateM.maximumRegionMonitoringDistance{ distance = locateM.maximumRegionMonitoringDistance } let region = CLCircularRegion(center: center, radius: distance, identifier: "xiaoxiao") //2.監聽區域 self.locateM.startMonitoringForRegion(region) //3.判斷當前狀態是否是在區域內還是區域外， //在`didDetermineState`代理方法中獲得結果 self.locateM.requestStateForRegion(region) } }}extension ViewController : CLLocationManagerDelegate{ func locationManager(manager: CLLocationManager, didEnterRegion region: CLRegion) { print("進入了區域"+region.identifier) } func locationManager(manager: CLLocationManager, didExitRegion region: CLRegion) { print("出了區域"+region.identifier) } func locationManager(manager: CLLocationManager, didDetermineState state: CLRegionState, forRegion region: CLRegion) { //獲取剛開始是否在區域內或者區域外 if region.identifier == "xiaoxiao"{ switch state { case .Inside: print("已經是區域內的") case .Outside: print("沒有在區域內") case .Unknown: print("不清楚") } } }}10、地理編碼與反地理編碼
地理編碼
let geoCoder = CLGeocoder()geoCoder.geocodeAddressString("廣州") { (pls:[CLPlacemark]?, error : NSError?) in if error == nil{ print("地址編碼成功") print(pls?.last?.location) }else{ print("錯誤 /(error)") } }打印
地址編碼成功
Optional(<+23.12517800,+113.28063700> +/- 100.00m (speed -1.00 mps / course -1.00) @ 8/14/16, 9:49:22 PM China Standard Time)
反地理編碼
let geoCoder = CLGeocoder()geoCoder.reverseGeocodeLocation(CLLocation(latitude:23.125,longitude: 113.280)) { (pls:[CLPlacemark]?, error:NSError?) in if error == nil{ print("地址反編碼成功 城市:/(pls?.last?.locality)") print(pls?.last?.addressDictionary) }else{ print("錯誤 /(error)") } }打印
地址反編碼成功 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])
注意同一個CLGeocoder對象，不能同時編碼與反編碼
比如
let geoCoder = CLGeocoder()geoCoder.geocodeAddressString("廣州") { (pls:[CLPlacemark]?, error : NSError?) in ...}geoCoder.reverseGeocodeLocation(CLLocation(latitude:23.125,longitude: 113.280)) { (pls:[CLPlacemark]?, error:NSError?) in ... }這樣只會打印第一個編碼成功的結果
11、CLPlacemark對象詳解
@NSCopying public var location: CLLocation? { get } //經緯度@NSCopying public var region: CLRegion? { get } //所關聯的地理區域@available(iOS 9.0, *)@NSCopying public var timeZone: NSTimeZone? { get } //時間域public var addressDictionary: [NSObject : AnyObject]? { get } //詳細地址信息//addressDictionary中的屬性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 } //城市名稱public var subLocality: String? { get } //鄰城市名稱public var administrativeArea: String? { get } //行政區域 比如:CApublic var subAdministrativeArea: String? { get } //子行政區域public var postalCode: String? { get } //郵政編碼public var ISOcountryCode: String? { get } //國家代碼表public var country: String? { get } //國家public var inlandWater: String? { get } //內陸水域public var ocean: String? { get } //海洋public var areasOfInterest: [String]? { get } //興趣點以上這篇iOS中的地理位置的獲取及plist設置方法就是小編分享給大家的全部內容了，希望能給大家一個參考，也希望大家多多支持VEVB武林網。
