Benjamin Hill commented on CB-402:
----------------------------------
v2.3.0: Have a few minute wait time when returning results against a ~2000
entry address book, and searching on all fields/all results.
> 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 Cordova
> Issue Type: Improvement
> Components: iOS
> Reporter: Shazron Abdullah
> Priority: Minor
> Labels: benchmark, unit-test
> Fix For: 2.4.0

> 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
