Getting attribute dictionaries from NSAttributedString

How to get NSAttributedString attributes?

I thought using enumerateAttributesInRange:NSMakeRange(0, str.length)and then storing all the attributes in NSMutableDictionaries, but I would like to know if there is a better way.

EDIT ------ My problem is what I have NSAttributedStringand I want to use this function in my attributes ...

CTFramesetterSuggestFrameSizeWithConstraints(framesetter,range, __ATTRIBUTES__, size , NULL);
