I'm assuming that User is a real Objective-C class and not just a C struct.
If so, then you'd do something like this:
NSPredicate* predicate = [NSPredicate predicateWithFormat:@"state = 1"];
NSArray* firstArray = [allObjects filteredArrayUsingPredicate:predicate];
predicate = [NSPredicate predicateWithFormat:@"state = 2"];
NSArray* secondArray = [allObjects filteredArrayUsingPredicate:predicate];
