Swift基础 - - 高德地图实践

高德地图开发需要自己到官网http://lbs.amap.com/console/ 注册一个ak，新建一个swift工程，然后在Info.plist中添加一个NSLocationAlwaysUsageDescription或者NSLocationWhenInUseUsageDescription。

高德地图的库以及依赖库加入到项目里面

需要的库如下截图：

添加头文件

具体的方式见Swift基础－－调用第三方OC项目，在Bridging-Header.h中加入如下代码，这样我们就可以调用高德地图相关的接口

 #import <MAMapKit/MAMapKit.h>
 #import <AMapSearchKit/AMapSearchAPI.h>

基础地图类实现

基础类里面编写地图相关的初始化以及功能的开发，界面如下：包含定位，数据刷新，放大缩小添加以及功能实现。
