Question

I have an Cocoa Core-Date Application. I added a search field and bound it. Now, I have tried to add some predicates but failed! Here are my two questions:

First, the predicate should filter NSNumbers but I cannot build a working predicate. My try:

keyPath == [NSNumber numberWithInteger:[$value integerValue]]

(keyPath represents a NSNumber which stores an integer.)

Second, I want to have a predicate which searches in two attributes. The first attribute is firstName and the other lastName. So, if the user types “John Appleseed” he gets an result but with my tries I only get firstName or lastName.

Thanks for your help, if there are any questions ask them. I dont know if I described my problem detailed enough 😉
