《http://blog.csdn.net/shuaiyinoo》谢谢

今天是百度地图的最后一个博客的更新了，看了上面几篇博客不知道大家有没有感受或者有没有什么体会，基本上百度地图提供的查询的方法基本上都是异步调用的，通过异步调用显示在 MySearchListener implements MKSearchListener 实现了这个接口的各个方法当中

当然这次的经纬度查询和转换同样是在这里面有所体会，在进行经纬度转换的时候，只需要调用百度地图的下面两个方法，就可以成功的知道如何进行经纬度的转换了

总得来说百度地图做起来比Google地图的API做起来简单，原因可能就是应为百度地图的API是中文的，中国人开发的更加适合中国人的使用习惯等等，加油，成功是所于大家的，下面我就把这一几篇博客的核心代码贴出来，供大家参考参考

然后附上这几个博客的总体的项目，请大家笑纳......有很多不足的地方还请大家多多包含......
