iOS百度地图开发集成使用

项目需要集成百度地图&＃xff0c;那么关于如何集成百度地图的事&＃xff0c;就自己去百度开放平台查看文档吧&＃xff0c;这是非常简单的事&＃xff0c;在这里就不多说了。

那么下面我就说说我在这个demo里所做的事。

首先&＃xff0c;项目需要具备定位及计算两地的距离

其次&＃xff0c;项目需要根据两个地点来拿到所有路线&＃xff0c;并且可根据不同的策略拿到对应的最佳路线。

最后&＃xff0c;需要拿到打车相关信息

那么这里我就自己写了一个单例类&＃xff0c;这是在内部处理所有的代理&＃xff0c;外部可以非常方便地调用&＃xff0c;如果有好的建议&＃xff0c;请在评论中赐教&＃xff0c;谢谢&＃xff01;
