I want to delete contact of iphone manually(with number by number). Can anyone help me to do the same. I have done with deleting contact using method
ABAddressBookRemoveRecord(addressBook, record, nil);
This method makes me to delete a single contact with all of its record but I want to do delete manually means want to delete single number of the existing contact if it has multiple numbers. The given image says the requirement.
You Can refer following links which will be helpful to you......
iOS - add contact into Contacts?
With the help of these links you can know to add contact to iphone OS programatically...
To resolve this problem you have to get the existing contact object(ABRecordRef object) which you have to update ,get the number property label object which contains all the numbers,remove the number which u want to delete from the ABMutableMultiValueRef of the numbers which u have to prepare.Then after doing all the stuffs... use following code...
ABRecordSetValue(person, kABPersonPhoneProperty, multiPhone,nil);
Then save the addressbook using following code....
ABAddressBookSave(iPhoneAddressBook, &error);
This code is on the basis of my R&D, try this it must work....Thanks!!!
In order to delete all contacts form iPhone, you have them syncing with another source (gmail, windows contacts, Yahoo, etc.) then in iTunes, select your iPhone under devices (left side), go to Info (top), deselect "Sync contacts with".
When you do this, it will ask you to remove your contacts or not. Click on "Remove Contacts", and then Apply (botton right).
If you don't have your contacts sync'd, then you can either setup a temporary sync to what service you have access to and then do the above, or do them one at a time.
