iOS NSMutableString split like java's String method split()

I hava a NSString which uses $ as delimiters, e.g.

    NSMutableString *str = @"AA$BB$CC";
 

So, my questio is: is there a method to split that NSMutableString by delimiters '$' and store into an array,
just like in java:

    String[] list = str.split()
 

thanks advancde.
