Becky Gibson commented on CB-402:
---------------------------------
FWIW I did look into this when I implemented Contacts. I don't think predicates work with
the results of ABAddressBookCopyArrayOfAllPeople. Of course, I was really new to objective-c/iOS
back then so YMMV.
> Improve Contacts search taking a long time by using (NSArray*)filteredArrayUsingPredicate:(NSPredicate*)predicate

> We have to analyze this first to see if it is a big problem, with a huge N. I believe
it is.
> Right now our search method is O( n ), while using Apple's search method it is possibly
O( log n ) - but that's just a guess if I assume internally they use a binary search.
> Steps:
> 1. Grab all the contacts in a NSArray through ABAddressBookCopyArrayOfAllPeople
> 2. Construct a NSPredicate for the filter, and call filteredArrayUsingPredicate on the
NSArray returned in step 1.
> 3. Convert the NSArray returned in step 2. to our CDVContact objects
