【移動應(yīng)用開發(fā)技術(shù)】iOS中如何獲取地理位置及設(shè)置plist

在下給大家分享一下iOS中如何獲取地理位置及設(shè)置plist，希望大家閱讀完這篇文章之后都有所收獲，下面讓我們一起去探討吧！1、在前臺的時候獲取地理位置信息ios8/9在info.plist中配置NSLocationWhenInUseUsageDescription的值，否則上面的方法無效調(diào)用.requestWhenInUseAuthorization()獲取前臺獲取地理位置權(quán)限調(diào)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(jīng)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(diào)用.requestWhenInUseAuthorization()獲取前臺獲取地理位置權(quán)限在info.plist中配置NSLocationWhenInUseUsageDescription的值，否則上面的方法無效設(shè)置Capabilities>BackgroundModes>LocationUpdates打?qū)凑{(diào)用.startUpdatingLocation()ios9調(diào)用.requestWhenInUseAuthorization()獲取前臺獲取地理位置權(quán)限設(shè)置.allowsBackgroundLocationUpdates=true(ios9需要執(zhí)行)在info.plist中配置NSLocationWhenInUseUsageDescription的值，否則上面的方法無效設(shè)置Capabilities>BackgroundModes>LocationUpdates打?qū)?如果第二步做了，此步?jīng)]做，直接crash)調(diào)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(jīng)更新")

}

}3、后臺獲取，后臺獲取的時候，屏幕上方無藍框提示調(diào)用.requestAlwaysAuthorization()獲取前臺獲取地理位置權(quán)限在info.plist中配置NSLocationAlwaysUsageDescription的值，否則上面的方法無效設(shè)置.allowsBackgroundLocationUpdates=true(ios9需要執(zhí)行)設(shè)置Capabilities>BackgroundModes>LocationUpdates打?qū)?本步驟在ios8中可以不做設(shè)置，但是在ios9中如果第三步做了，而此步?jīng)]有做，直接crash)調(diào)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(jīng)更新")

}

}4、權(quán)限改變的通知注意：在Denied或者NotDetermined的狀態(tài)下startUpdatingLocation,開始監(jiān)聽之后,當狀態(tài)改變成允許的狀態(tài)時，會直接進入監(jiān)聽狀態(tài)，不必再次調(diào)用startUpdateingLocationfunc

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(guān)閉了定位服務(wù)")

}

case

.NotDetermined:

print("第一次，尚未決定")

case

.Restricted:

print("沒有權(quán)限的")

}

}5、過濾距離很多時候我們需要監(jiān)聽函數(shù)只調(diào)用一次來獲取用戶當前的位置在監(jiān)聽函數(shù)中停止監(jiān)聽設(shè)置監(jiān)聽的過濾距離//如果監(jiān)聽器已經(jīng)開啟,此值修改之后立即生效

self.locateM.distanceFilter

=

100

//每100米，調(diào)用一次監(jiān)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

if(CLLocationManager.headingAvailable()){

self.locateM.startUpdatingHeading()

}else{

print("當前磁力計有問題")

}

}

}

extension

ViewController

:

CLLocationManagerDelegate{

func

locationManager(manager:

didUpdateHeading

newHeading:

{

//1.拿到當前設(shè)備對正朝向的角度

//3.反向旋轉(zhuǎn)照片

UIView.animateWithDuration(0.5)

{

self.mImageView.transform

=

CGAffineTransformMakeRotation(-hudu)

}

}

}9、區(qū)域的監(jiān)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(yīng)該判斷當前是否可以監(jiān)聽某個區(qū)域

if

CLLocationManager.isMonitoringAvailableForClass(CLCircularRegion){

//1.創(chuàng)建區(qū)域

let

center

=

CLLocationCoordinate2DMake(21.123,

121.345)

var

distance

:

CLLocationDistance

=

1000

//限制監(jiān)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(jiān)聽區(qū)域

self.locateM.startMonitoringForRegion(region)

//3.判斷當前狀態(tài)是否是在區(qū)域內(nèi)還是區(qū)域外，

//在`didDetermineState`代理方法中獲得結(jié)果

self.locateM.requestStateForRegion(region)

}

}

}

extension

ViewController

:

CLLocationManagerDelegate{

func

locationManager(manager:

CLLocationManager,

didEnterRegion

region:

CLRegion)

{

print("進入了區(qū)域"+region.identifier)

}

func

locationManager(manager:

CLLocationManager,

didExitRegion

region:

CLRegion)

{

print("出了區(qū)域"+region.identifier)

}

func

locationManager(manager:

CLLocationManager,

didDetermineState

state:

CLRegionState,

forRegion

region:

CLRegion)

{

//獲取剛開始是否在區(qū)域內(nèi)或者區(qū)域外

if

region.identifier

==

"xiaoxiao"{

switch

state

{

case

.Inside:

print("已經(jīng)是區(qū)域內(nèi)的")

case

.Outside:

print("沒有在區(qū)域內(nèi)")

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>

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:

,

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(jié)果11、CLPlacemark對象詳解@NSCopying
