You could create a dependent key, that depends on all your keys of interest,
then you just observe that one key. Like:
+ (NSSet*)keyPathsForValuesAffectingValueForKey:(NSString*)inKey
{
NSSet* set = [super keyPathsForValuesAffectingValueForKey:inKey];
if ([inKey isEqualToString:@"everything"])
{
set = [set setByAddingObjectsFromSet:[NSSet setWithObjects:
@"firstName",
@"lastName",
@"age",
nil]];
}
return set;
}
Cheers,
