ABPeoplePickerNavigationController在presentviewcontroller时崩溃

Question

Some one help me to fix this crash issue. I am not able to get the root cause of it.

ABPeoplePickerNavigationController *picker = [[ABPeoplePickerNavigationController alloc] init];
    [self presentViewController:picker animated:YES completion:nil];

And I am getting the below crash, not sure why,

-[ABPeoplePickerNavigationController masterViewController]: unrecognized selector sent to instance 0xdd8cd40

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[ABPeoplePickerNavigationController masterViewController]: unrecognized selector sent to instance 0xdd8cd40'
