PredicateEditor is an open source component from Arvindh Sukumar for creating NSPredicates at runtime using a visual editor allowing the user to easily filter data.
PredicateEditor allows filters for common data types such as Strings, NSDate, and different number types. Multiple filters can be defined, and the interface updates automatically.
