【移动应用开发技术】iOS中如何获取地理位置及设置plist

在下给大家分享一下iOS中如何获取地理位置及设置plist，希望大家阅读完这篇文章之后都有所收获，下面让我们一起去探讨吧！1、在前台的时候获取地理位置信息ios8/9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>LocationUpdates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(ios9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>LocationUpdates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(ios9需要执行)设置Capabilities>BackgroundModes>LocationUpdates打对勾(本步骤在ios8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startUpdateingLocationfunc

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

//kCLLocationAccuracyThreeKilometers7.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

CLLocationSpeed

{

get

}

//当前的速度

public

var

timestamp:

{

get

}

//位置确定的时间戳

public

var

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)

->

CLLocationDistance8、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>

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:

Tongjin

)

,

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
