关于百度地图缩放级别

百度地图自身有17个级别，如下：

{"20m","50m","100m","200m","500m","1km","2km","5km","10km","20km","25km","50km","100km","200km","500km","1000km","2000km"}

但是，提供的开发包只支持16个级别， Level: 3~18, 比例尺如下：

{"50m","100m","200m","500m","1km","2km","5km","10km","20km","25km","50km","100km","200km","500km","1000km","2000km"}

最近在开发百度地图API相关功能，发现很多有趣的东西。昨晚在研究如何反复往地图上添加删除一个标记点，卡住了，没有解决。

今早起床上厕所，突然想到了解决方法，真是一件很神奇的事情。
