Implement the right folder function

[KimSamHyun]

Using the BEFoldMenuViewController library

I want to put the folder function on the right side but it is not implemented properly.

Have you ever implemented it?

Draggin ok
rightMenuAction function not ok

Oh, sorry, I haven't implemented it. I wish i could, but I do not have time now, really sorry. You can read my code, and do what you want in similar way. Sorry for can not help you right now.
