Is it possible to retrieve the create time of the iPhone contacts record?

Question

Hi, everyone,

I want to ask a question about iPhone. Is it possible to retrieve the creation time from the iPhone contacts of each record? Thank you.

Answer 1

Yes. You want the kABPersonCreationDateProperty. See the reference.

NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setTimeStyle:NSDateFormatterMediumStyle];
[dateFormatter setDateStyle:NSDateFormatterMediumStyle];    

ABAddressBookRef addressBook = ABAddressBookCreate();

NSArray* allPeople = (NSArray*) ABAddressBookCopyArrayOfAllPeople( addressBook );
for( id aPerson in allPeople ) {
    NSString* firstName = (NSString*) ABRecordCopyValue( aPerson, kABPersonFirstNameProperty );
    NSString* lastName = (NSString* ) ABRecordCopyValue( aPerson, kABPersonLastNameProperty );
    NSDate* createDate = (NSDate*) ABRecordCopyValue( aPerson, kABPersonCreationDateProperty );
    NSString* formattedDate = [dateFormatter stringFromDate:createDate];

    NSLog( @"%@ %@ created %@", firstName, lastName, formattedDate );

    [firstName release];
    [lastName release];
    [createDate release];
}

[allPeople release];
[dateFormatter release];
CFRelease(addressBook);

Which outputs...
