iOS新建联系人崩溃问题

Question

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

    ABRecordRef newPerson = [AddressBookUtils newPersonName:userName phoneNum:phoneNum label:@""];
    [AddressBookUtils addEmail:email label:@"" toRecordRef:newPerson];
    newPersonVC.displayedPerson = newPerson;

    [self.navigationController pushViewController:newPersonVC animated:YES];

弹出通讯录联系人新建页面，在iOS7上点击打开铃声或震动设置页面，点击返回Crash.
