**SensorTag-iOS监测数据本地txt存储方案修改**  
**引子：**  
最近公司在研究关于`TI`的`SensorTag CC2650`相关开发板的相关套件。需要将测试数据储存下来，方便进行下一步研究。这边`SensorTag-iOS`源码`github`下载地址为：

[https://github.com/JarvisW/SensorTag-iOS][https_github.com_JarvisW_SensorTag-iOS]

**思路：**  
这边需要将监测到的角速度，x、y、z，重力加速度x、y、z总共6个值进行存储。  
1、存储文件txt命名用日期来存储。例如：20160330.txt。  
2、每一个数据，存储一行，之间用“，”拼接。每条数据之后，再拼接一个日期“12：04：22”（时：分：秒）。  
例如一条数据记录为：`0.1,0.4,0.9,-0.7,-27.3,-5.4，11:17:34`  
3、SensorTag套件采集数据1S采集10次。  
**代码：**  
说明：代码修改的项目中的`sensorTagMovementService.m`文件
