How to do it using objective-c???????, please any one reply!! also tell me what api or method of objective-c to use

Moved to the development forum. Please keep this in mind for the future.

I'm not sure that you need an API here. Indeed, recursion is your best friend here. Modify this and recurse over it if you run into folders along the way.
