You might take a look at ERXInQualifier from ProjectWonder. See http://wonder.sourceforge.net/javadoc/er/extensions/ ERXInQualifier.html and http://wonder.sourceforge.net/

Or you could just use EOOrQualifier since an "IN" qualifier is a short cut for "OR"ing several qualifiers. You could merely iterate through the list of types you want to qualify for adding a regular EOQualifier to an NSMutableArray on each iteration. Then you can use that NSMutableArray as an argument to the EOOrQualifier constructor to produce the qualifier you need.
