Setting the address book image for a contact does not work

Question

I am trying to establish a contact image using the code below. I do not see any errors, and the image is not saved in the contact entry in the address book. Please help! I have to do something wrong ...

- (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person
{
[abcontroller setDisplayedPerson:person];

UIImage *im = [UIImage imageNamed:@"image1.jpg"];
NSData *dataRef = UIImagePNGRepresentation(im);
CFErrorRef error;
ABAddressBookRef addressBook = ABAddressBookCreate(); 

NSLog(@"Error:",error);
    if (ABPersonSetImageData(person, (CFDataRef)dataRef, &error))
    {
        NSLog(@"Set contact photo %@", error);
        if (ABAddressBookHasUnsavedChanges(addressBook))
        {
            NSLog(@"Changes made to address book");
        }
        else {
            NSLog(@"No changes made to address book");
        }

        if (ABAddressBookSave(addressBook, &error))
        {
            NSLog(@"Saved");

        }
        else {
            NSLog(@"Not saved");
        }


    }
    else {
        NSLog(@"Error saving contact photo %@", error);
    }
ABAddressBookSave(addressBook, &error);

[self dismissModalViewControllerAnimated:YES];    

return NO;
}

Here is my output log:

2010-01-17 21:58:35.465 Error:
2010-01-17 21:58:35.504 Set contact photo <ABPeoplePickerNavigationController: 0x19e9b0>

I'm not sure why the error object is registered as an ABPeoplePickerNavigationController object?

Answer 1

As for I'm not sure why the error object is registered as an ABPeoplePickerNavigationController object? - because you are not initializing correctly errorhere:

CFErrorRef error;

nil , (, , ), , ABPeoplePickerNavigationController.

: , person, , ? ABAddressBookGetPersonWithRecordID, ABPersonRef , .

Answer 2

. :

ABAddressBookRef addressBook = ABAddressBookCreate(); 

ABAddressBookRef addressBook = [peoplePicker addressBook];

ABAddressBookRef libroDirec = [peoplePicker addressBook];//don't create
        ABPersonSetImageData(person, (CFDataRef)UIImagePNGRepresentation(display.image), &cfError);
        ABAddressBookAddRecord(libroDirec, person, &cfError);

        if (ABAddressBookSave(libroDirec, nil)) {
            NSLog(@"\n%s saved successfuly", _cmd);
        } else {
            NSLog(@"\n%s something bad happen while saving", _cmd);
        }
