How to add contact from within an iPhone app?

I am looking to keep track of people in my iPhone app - either adding them from existing contact data, or prompting the user to enter a new contact which will be saved to their Contacts.

I know I 开发者_运维问答can create a persons record add write it to the Contact book, is it possible to display this screen?

Or do I have to implement my own view to facilitate creating a contact entry?

Apple provides ABNewPersonViewController. If you'd like some sample code, see Quick Contacts, in particular, this section:

ABNewPersonViewController *picker = [[ABNewPersonViewController alloc] init];
picker.newPersonViewDelegate = self;

UINavigationController *navigation = [[UINavigationController alloc] initWithRootViewController:picker];
[self presentModalViewController:navigation animated:YES];

[picker release];
[navigation release];

Have you tried using the ABNewPersonViewController?
See this and look for the section titled "Prompting the User to Create a New Person Record".

Below code can use for all IOS version, #import ,#import

ABPeoplePickerNavigationController *peoplePicker;

peoplePicker=[[ABPeoplePickerNavigationController alloc] init];
