Guessing a user’s favorite contacts on iOS

Demo application screenshot

This repository contains code for an App Store-legal heuristic that guesses the favorite contacts in a user’s address book on iOS. Many iOS apps provide an "invite your friends" feature. From a usability design perspective it is desireable that the app suggests friends that are likely to be invited by the user.

The code is described in closer detail in this blog post.

Example Usage

The implementation of the heuristic is contained in DBFriendInviter.h and DBFriendInviter.m.

This will give you the 10 most important contacts in the address book:

#import "DBFriendInviter.h"
NSArray *contacts = [DBFriendInviter mostImportantContacts];

The returned list consists of an NSArray of ABRecordIDs. Each ABRecordID is wrapped in an NSNumber instance. The list is sorted by descending importance, i.e. the most important contacts are first.

You can also change the number of returned results or exclude a set of blacklisted contacts using the following function:

NSMutableSet *blacklistedContacts = [NSMutableSet set];
[set addObject:@(recordID_1)];
// ...
[set addObject:@(recordID_N)];

NSArray *contacts = [DBFriendInviter mostImportantContactsWithIgnoredRecordIDs:blacklistedContacts
                                                                    maxResults:20];

Demo application

The repository contains a demo application for iOS 6.
