在我們的生活中現(xiàn)在很多App大多都可以獲取地理位置進(jìn)行相關(guān)的定位標(biāo)記等,有的例如餐飲App,當(dāng)我們需要訂餐時(shí),我們需要知道商家的地理位置,以方便我們能夠知道送餐人員大概需要多久可以將食物送到我們面前,當(dāng)我們需要查找某個(gè)餐廳的時(shí)候,我們只需要在搜索框中搜索相應(yīng)的店名,我們的App就能迅速的在地圖上幫我們標(biāo)注出來,以方便我們查看,當(dāng)我們需要去一個(gè)陌生的地方的時(shí)候,我們可以很輕松的通過導(dǎo)航功能,去往我們想要去得任何地方,而這些都得益于蘋果為我們提供的定位服務(wù)。
- 首先要實(shí)現(xiàn)地圖、導(dǎo)航功能,就需要我們先熟悉定位功能,在iOS中通過Core Location框架進(jìn)行定位操作。Core Location自身可以單獨(dú)使用,和地圖開發(fā)框架MapKit完全是獨(dú)立的,但是往往地圖開發(fā)要配合定位框架使用。在Core Location中主要包含了定位、地理編碼(包括反編碼)功能。
- 由于目前蘋果iOS系統(tǒng)最新版本為9.1,蘋果自iOS8以后如果要使用定位服務(wù),需要我們?cè)趐list文件中多添加兩個(gè)字段,其實(shí)就是提示用戶授權(quán)的用的,就是以下兩個(gè)字段:
NSLocationWhenInUseUsageDescription 當(dāng)用戶使用的允許
NSLocationAlwaysUsageDescription 總是允許
定位服務(wù)授權(quán)狀態(tài)枚舉類型說明:
//定位服務(wù)授權(quán)狀態(tài),返回枚舉類型:
//kCLAuthorizationStatusNotDetermined: 用戶尚未做出決定是否啟用定位服務(wù)
//kCLAuthorizationStatusRestricted: 沒有獲得用戶授權(quán)使用定位服務(wù),可能用戶沒有自己禁止訪問授權(quán)
//kCLAuthorizationStatusDenied :用戶已經(jīng)明確禁止應(yīng)用使用定位服務(wù)或者當(dāng)前系統(tǒng)定位服務(wù)處于關(guān)閉狀態(tài)
//kCLAuthorizationStatusAuthorizedAlways: 應(yīng)用獲得授權(quán)可以一直使用定位服務(wù),即使應(yīng)用不在使用狀態(tài)
//kCLAuthorizationStatusAuthorizedWhenInUse: 使用此應(yīng)用過程中允許訪問定位服務(wù)

地理編碼與反地理編碼

- 反地理編碼:根據(jù)經(jīng)緯度獲取詳細(xì)的地址信息(比如:省市、街區(qū)、樓層、門牌等信息)
地理編碼與反地理編碼用到得兩個(gè)方法

除了可以使用MapKit框架進(jìn)行地圖開發(fā),對(duì)地圖有精確的控制和自定義之外,如果對(duì)于應(yīng)用沒有特殊要求的話選用蘋果自帶的地圖應(yīng)用也是一個(gè)不錯(cuò)的選擇。想使用蘋果自帶的地圖,我們需要用到MapKit中的MKMapItem類,這個(gè)類中有如下兩個(gè)方法:
- openInMapsWithLaunchOptions:用于在地圖上標(biāo)注一個(gè)位置
- openMapsWithItems: launchOptions:除了可以標(biāo)注多個(gè)位置外還可以進(jìn)行多個(gè)位置之間的駕駛導(dǎo)航
MKLaunchOptionsDirectionsModeKey :路線模式,常量
- MKLaunchOptionsDirectionsModeDriving 駕車模式
- MKLaunchOptionsDirectionsModeWalking 步行模式
MKLaunchOptionsMapTypeKey:地圖類型,枚舉
- MKMapTypeStandard :標(biāo)準(zhǔn)模式
- MKMapTypeSatellite :衛(wèi)星模式
- MKMapTypeHybrid :混合模式
MKLaunchOptionsMapCenterKey:中心點(diǎn)坐標(biāo),CLLocationCoordinate2D類型
MKLaunchOptionsMapSpanKey:地圖顯示跨度,MKCoordinateSpan 類型
MKLaunchOptionsShowsTrafficKey:是否 顯示交通狀況,布爾型
MKLaunchOptionsCameraKey:3D地圖效果,MKMapCamera類型
