I used iApple's code above as a starting point and created a working version from it - this one just collects all address book entries in an array. As mentioned above the original iApple doesn't work, there's a few bugs in it. This one works, and was tested.

Note: This doesn't return any contacts that don't have a name set - you can remove that for your own code, I just did it because I only need contacts with names set, and NSMutableDictionary doesn't like nil entries (crashes).

In my own address book I have a few entries that are just an email - I am not sure how they got there, but it's certainly possible to have address book entries without a name. Keep that in mind when iterating over an address book.

I am using the full name as per Apple's recommendations - ABRecordCopyCompositeName returns a composite of first and last name in the order specified by the user.

Finally, I made this a static method and put it in a helper class.

This is for use with ARC!

// returns an array of dictionaries
// each dictionary has values: fullName, phoneNumbers, emails
// fullName is a string
// phoneNumbers is an array of strings
// emails is an array of strings
+ (NSArray *)collectAddressBookContacts {
    NSMutableArray *allContacts = [[NSMutableArray alloc] init];
    ABAddressBookRef addressBook = ABAddressBookCreate();
    CFArrayRef people  = ABAddressBookCopyArrayOfAllPeople(addressBook);
    for(int i = 0;i
