As a workaround you can create PHOTO field inside of VCard.

<pre><code>NSError* error = nil;
NSData* vCardData = [CNContactVCardSerialization dataWithContacts:@[contact] error:&amp;error];
NSString* vcString = [[NSString alloc] initWithData:vCardData encoding:NSUTF8StringEncoding];
NSString* base64Image = contact.imageData.base64Encoding;
NSString* vcardImageString = [[@"PHOTO;TYPE=JPEG;ENCODING=BASE64:" stringByAppendingString:base64Image] stringByAppendingString:@"\n"];
vcString = [vcString stringByReplacingOccurrencesOfString:@"END:VCARD" withString:[vcardImageString stringByAppendingString:@"END:VCARD"]];
vCardData = [vcString dataUsingEncoding:NSUTF8StringEncoding];
</code></pre>

For some reasons CNContactVCardSerialization does not use any photo of contact. VCard after serialization is looks like:

<pre><code>BEGIN:VCARD
VERSION:3.0
PRODID:-//Apple Inc.//iPhone OS 9.3.2//EN
N:Contact;Test;;;
FN: Test Contact 
END:VCARD
</code></pre>

After insertion the PHOTO field inside VCard you will get

<pre><code>BEGIN:VCARD
VERSION:3.0
PRODID:-//Apple Inc.//iPhone OS 9.3.2//EN
N:Contact;Test;;;
FN: Test Contact 
PHOTO;TYPE=JPEG;ENCODING=BASE64:&lt;photo base64 string&gt;
END:VCARD
</code></pre>

After this insertion contact will looks fine in CNContactViewController

For N number of contacts, you can add image data into VCF by using simple method as below.

<pre><code>-(NSData*)getVCFDataWithImagesFromContacts:(NSArray*)arrContacts
{
//---- Convert contacts array into VCF data.
 NSError *error;
 NSData *vcfData = [CNContactVCardSerialization dataWithContacts:arrContacts error:&amp;error];

 NSString *strVCF = [[NSString alloc] initWithData:vcfData encoding:NSUTF8StringEncoding];

 //--- Split contacts from VCF.
 NSMutableArray *arrSplit = (NSMutableArray*)[strVCF componentsSeparatedByString:@"END:VCARD"];
 [arrSplit removeLastObject];//-- if object is "\r\n" otherwise comment this line.

 //--- Validate array count
 if (arrSplit.count == arrContacts.count)
 {
 for (int index=0;index&lt;arrContacts.count;index++)
 {
 //--- Get current contact and VCF contact string.
 CNContact *contact = arrContacts[index];
 NSString *strContact = arrSplit[index];

 //--- Get base64 string of image.
 NSString* base64Image = [UIImagePNGRepresentation([ViewController imageWithImage:[UIImage imageWithData:contact.imageData] scaledToSize:CGSizeMake(50,50)]) base64EncodedStringWithOptions:NSDataBase64EncodingEndLineWithCarriageReturn];

 //--- Append image tag into contact string.
 NSString* vcardImageString = [[@"PHOTO;ENCODING=BASE64;JPEG:" stringByAppendingString:base64Image] stringByAppendingString:@"\r\n"];
 strContact = [strContact stringByAppendingString:[NSString stringWithFormat:@"%@%@",vcardImageString,@"END:VCARD\r\n"]];

 //--- Update contact string from array.
 [arrSplit replaceObjectAtIndex:index withObject:strContact];
 NSLog(@"strContact :%@",strContact);
 }
 }

 //--- Combine all contacts together in VCF.

I'd like to improve upon and modernise for Swift 3 the excellent answer by kudinovdenis.

Just put the following extension into your project

<pre><code>import Foundation
import Contacts

extension CNContactVCardSerialization {
 internal class func vcardDataAppendingPhoto(vcard: Data, photoAsBase64String photo: String) -&gt; Data? {
 let vcardAsString = String(data: vcard, encoding: .utf8)
 let vcardPhoto = "PHOTO;TYPE=JPEG;ENCODING=BASE64:".appending(photo)
 let vcardPhotoThenEnd = vcardPhoto.appending("\nEND:VCARD")
 if let vcardPhotoAppended = vcardAsString?.replacingOccurrences(of: "END:VCARD", with: vcardPhotoThenEnd) {
 return vcardPhotoAppended.data(using: .utf8)
 }
 return nil

 }
 class func data(jpegPhotoContacts: [CNContact]) throws -&gt; Data {
 var overallData = Data()
 for contact in jpegPhotoContacts {
 let data = try CNContactVCardSerialization.data(with: [contact])
 if contact.imageDataAvailable {
 if let base64imageString = contact.imageData?.base64EncodedString(),
 let updatedData = vcardDataAppendingPhoto(vcard: data, photoAsBase64String: base64imageString) {
 overallData.append(updatedData)
 }
 } else {
 overallData.append(data)
 }
 }
 return overallData
 }
}
</code></pre>

and then you can use it similarly to the existing serialisation method:

<pre><code>CNContactVCardSerialization.data(jpegPhotoContacts: [contact1, contact2])
</code></pre>

Note that this takes care of serialisation, you'll need to write a similar method for deserialisation if you are also importing.

I'm using CNContacts and CNContactUI framework and picking a contact via this

<pre><code>CNContactPickerViewController *contactPicker = [CNContactPickerViewController new];
 contactPicker.delegate = self;
 [self presentViewController:contactPicker animated:YES completion:nil];
</code></pre>

and

<pre><code>-(void)contactPicker:(CNContactPickerViewController *)picker didSelectContact:(CNContact *)contact
{
 NSArray *array = [[NSArray alloc] initWithObjects:contact, nil];
 NSError *error;
 NSData *data = [CNContactVCardSerialization dataWithContacts:array error:&amp;error];
 NSLog(@"ERROR_IF_ANY :: %@",error.description);
}
</code></pre>

This contact object have contact.imageData and coming in logs. But when I tried to cross check this data by

<pre><code>NSArray *contactList = [NSArray arrayWithArray:[CNContactVCardSerialization contactsWithData:data error:nil]];
CNContact *contactObject = [contactList objectAtIndex:0];
</code></pre>

This is getting null:

<pre><code>//contactObject.imageData 
</code></pre>

Why am I getting this null and this contact has image when check in contacts?

How to get VCF data with contact images using CNContactVCardSerialization dataWithContacts: method?
