Hello,
Does Core Data provide a mechanism for checking the existence of a given record without performing a fetch?

From http://developer.apple.com/documentation/Cocoa/Conceptual/ CoreData/index.html?http://developer.apple.com/documentation/Cocoa/ Conceptual/CoreData/Articles/cdTroubleshooting.html

"To retrieve data using a managed object context, you create a fetch request."

Any particular reason you do not want to use fetch requests?

For example, a method that returns "true" if a record containing a given attribute value exists.

Something like: - (BOOL) recordExistsForKey:Value

You can write your own....


Thanks,
Charles
