IOS learning and ios development

In the IOS 9 SDK, Apple abolished some of the AddressBookUI. framework Functions (whether the library has been abolished and needs to be verified). The specific system interfaces related to saving contacts are as follows:
Contact Selection: AddressBookUI/abw.lepickernavigationcontroller. h
Contact details: AddressBookUI/ABPersonViewController. h
Unknown contact: AddressBookUI/ABUnknownPersonViewController. h
Create a contact: AddressBookUI/ABNewPersonViewController. h
Use in the new SDK
Contact: ContactsUI/CNContactPickerViewController. h
Contact details, new contacts, and unknown contacts: ContactsUI/CNContactViewController. h (create using different methods, as described below)

In the following example, the problem persists.

1. The title of UINavgationController and the Left and Right items are all built-in by the system. When the contact details are met, the return button of navgationItem does not have a click event. How can this problem be customized?

2. The contact logo is black screen (the real machine test has obtained the permission ).
