See the "Set and Array Operators" inside the "Key-Value Coding Programming Guide". Example : @max The @max operator compares the objects returned by sending valueForKeyPath: to each item in the receiver array passing the key path to the right of the array operator as the parameter, returning the maximum value found. The maximum value is determined using the compare: method of the objects at the specified key path. The compared property objects must support comparison with each other. The following example returns the date of the latest transaction in the savings account: [savingsAccount valueForKeyPath:@"transactio...@max.date"] :: marcelo.alves _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
