标签:swift实现高德地图   高德地图   

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:

技术分享

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。
