vCard is a file format standard for electronic business cards. vCards are often attached to e-mail messages, but can be exchanged in other ways, such as on the World Wide Web or instant messaging. They can contain name and address information, telephone numbers, e-mail addresses, URLs, logos, photographs, and audio clips.
I have used Sadun's vcf tools but not compatible in iOS9.0 or later.So I rewrited the new one base on it.You can find the Sadun's code here.
Generate VCard String Just add VCGGenerator class files to the project and use method:
+ (NSString *)generateVCardStringWithRecID:(NSString *)contactIdString")which would return the VCard String.
Write VCardString
//It will be better that you save the contactId in NSUserDefaults or others.
CNContactStore *stroe = [[CNContactStore alloc]init];
id keysToFetch = @[[CNContactViewController descriptorForRequiredKeys]];
CNContact *contact = [stroe unifiedContactWithIdentifier:contactID keysToFetch:keysToFetch error:nil];
NSString *vcard = [VCFGenerator generateVCardStringWithContactID:contactIdString];
//Then you just need to write the result to the new xxxxx.vcf file.
[vcard writeToFile:[NSHomeDirectory() stringByAppendingFormat:@"/tmp"] atomically:YES encoding:NSUTF8StringEncoding error:nil];
iOS (9.0 and later)
