Answer 1

There are two frameworks for this. Address Book UI gives you some views to use. http://developer.apple.com/library/ios/#documentation/AddressBookUI/Reference/AddressBookUI_Framework/_index.html

Address Book doesn't, but it still gives you programmatic access to the address book. http://developer.apple.com/library/ios/#documentation/AddressBook/Reference/AddressBook_iPhoneOS_Framework/_index.html#//apple_ref/doc/uid/TP40007212

When we are using MFMessageComposeViewController , then it automatically gives the link of contacts. So no need of AddressBookUI Framework required in this case. In MFMessagecomposeViewController , contacts have to be added by clicking the "+" button on the right side of the add recipients field.
