How do I implement same contact picker as in iOS Apple Maps?

As you can see from pictures, in Maps app you can switch between favourites places and your contacts. I want switching between picker and some custom table without dismissal animation and with common control like UISegmentedControl.

I have no problem with presenting CNContactPickerViewController nor with implementing UISegmentedControl. I have problem with adding toolbar to CNContactPickerViewController.

  • I've tried to push it into my UINavigationController with no success.

  • I've tried to add UIToolbar but CNContactPickerViewController doesn't have UINavigationController.

  • I also tried to add it to subviews and childViewControllers

Documentation doesn't say anything how to use it. This page claims:

Instances of the CNContactPickerViewController cannot be pushed to the stack.

Any advice is appreciated :)

I'm pretty sure that CNContactPickerViewController is highly secure and runs in a separate process. I'm trying to find documentation to support that theory, but I think that's the reason why there's no API that allow devs to augment its appearance.

The reason you're seeing it in the Apple Maps app is because ... Apple apps can use private APIs. They're doing something special for their app which they haven't made publicly available.

    +1 to this. A bit more supporting evidence (though nothing conclusive): iOS doesn't require permission to display a `CNContactPickerViewController`, since the app only has access to the final selection. This means that it _can't_ allow access to its view hierarchy, or applications would be able to iterate the labels in the table view and read contact information that way. – Colin M Sep 01 '16 at 12:10
