I ' ve encountered a lot of unused variable while cleaning up
warnings . Should I just change the compile option to mask it ? Or should I just ignore the warning ?

[ilixiaocui]

Would you consider removing these variables if possible？

[Alipebt]

I don ' t know if unused variable will be used in the future , but I think I ' ll delete it . thank you.

Generally not, these should be manufactured with irregular coding.

@ilixiaocui I've noticed that there are some warnings from external libraries, do I need to clean them? If necessary, how to do it?
