ios 高地地圖實作定位

1. http://lbs.amap.com/ 注冊開發賬号、應用賬号擷取key

2. http://lbs.amap.com/api/ios-location-sdk/download下載下傳開發包，兩個都需要

3.ios工程配置：

Info.plist

添加配置：

<key>NSLocationAlwaysUsageDescription</key>
<string></string>
<key>NSLocationWhenInUseUsageDescription</key>
<string>親,需要開啟定位，可以嗎？</string>
<key>UIBackgroundModes</key>
<array>
	<string>location</string>
</array>
           

導入支援庫：

定位代碼：

引入頭檔案：

#import <AMapFoundationKit/AMapFoundationKit.h>
#import <AMapLocationKit/AMapLocationKit.h>
