检查一下，

    ABAddressBookRef _addressBookRef = ABAddressBookCreate();
    NSArray* allPeople = (NSArray *)ABAddressBookCopyArrayOfAllPeople(_addressBookRef);

   NSMutableDictionary  *contactsInformation = [[NSMutableDictionary alloc] initWithCapacity:[allPeople count]];

    for (id record in allPeople) 
    {
        NSMutableDictionary *propertyList = [[NSMutableDictionary alloc] init];


        CFTypeRef emailProp = ABRecordCopyValue((ABRecordRef)record, kABPersonEmailProperty);
        NSString *email = [((NSArray *)ABMultiValueCopyArrayOfAllValues(emailProp)) objectAtIndex:0 ];
        if (!email) {
            email = @"";  
        }

        [propertyList setObject:email forKey:@"Email"];

        [contactsInformation setObject:propertyList forKey:[NSNumber numberWithInt:ABRecordGetRecordID((ABRecordRef)record)]];

        [propertyList release];
    }
    CFRelease(_addressBookRef);
    [allPeople release];
    allPeople = nil;
