[iOS]天气查询

[iOS]天气查询

天气查询API：http://apistore.baidu.com/apiworks/servicedetail/112.html

Demo：http://download.csdn.net/download/u012881779/9474529

需导入库：CoreLocation.framework、libsqlite3.tbd、Foundation.framework、Mapkit.framework、CoreGraphics.framework

定位当前位置需要在info中进行设置：

     NSLocationAlwaysUsageDescription            String     YES
     NSLocationWhenInUseUsageDescription     String     YES
