Improve Contacts search taking a long time by using (NSArray*)filteredArrayUsingPredicate:(NSPredicate*)predicate
-----------------------------------------------------------------------------------------------------------------

                 Key: CB-402
                 URL: https://issues.apache.org/jira/browse/CB-402
             Project: Apache Callback
          Issue Type: Improvement
          Components: iOS
            Reporter: Shazron Abdullah
            Assignee: Shazron Abdullah


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
