iOS集成百度鹰眼时的坎坷里程

随着智能出行技术的普及，获取用户定位的需求在很多App中都很常见，似乎是用户的一举一动都在我们App后台的掌握之中。掌握用户的定位信息，也是很多后续App更好发展的前提条件，于是乎很多***(keng)钻(die)刻(chan)薄(pin)的需求便应运而生:包括实时获取用户定位、实时计算一定时间内的行驶距离、实时描绘车辆的行驶轨迹、监控车辆的形式速度、行驶习惯...(不说了，累死程序🐶不偿命，先让我哭会)。针对产品的需求，幸运的是这次提前告知，让我有充足的时间准备，这次就简单研究了一下百度API中的百度鹰眼服务，自我感觉挺吊的，简单集成了一下，包括获取实时位置信息，规定时间内的行驶距离，一定时间内的行驶轨迹点；话不多说，直接上干货。

1、集成前的准备工作，百度鹰眼官网的文档信息已经够详细了，我就不再班门弄斧了，地址：http://lbsyun.baidu.com/index.php?title=ios-yingyan/guide/createservice

2、百度鹰眼的工程配置文档也是较为详细，一步步来感觉不会出现什么大问题：http://lbsyun.baidu.com/index.php?title=ios-yingyan/guide/buildproject

3、针对百度鹰眼的SDK，我简单封装了一个工具类（菜鸟，无吐槽）,直接上代码吧，相应的方法都有相应的注释：

在需要使用鹰眼服务的时候直接调用相应的方法就行了.
