(4) COCOS2DX read CSV data file

There may be many types of read data files in COCOS2DX, such as reading Xml,lua,csv,json, which can be used as a format for configuration data.

Recently used to read the CSV data file, so on the internet to find a bit about this technology blog. Sure enough, the big gods on the internet are not stingy,

Don't talk nonsense, directly on the code. The code is as follows (test pass, readable data):
