通讯录联系人跳转

遇到一个通讯录跳转的问题，对于联系人来说，如果只有一个电话号码就直接dismiss返回，否则进入详情页进行选择后返回。在iOS 9.0系统前后可做如下处理：

 if([[UIDevice currentDevice] systemVersion].floatValue >= 9.0){

        CNContactPickerViewController *contactController = [CNContactPickerViewController new];

        contactController.delegate = self;

        [contactController setPredicateForSelectionOfContact:[NSPredicate predicateWithFormat:@"phoneNumbers.@count == 1"]];

        [controller presentViewController:contactController animated:YES completion:nil];

    }else{

       

        ABPeoplePickerNavigationController *peoplePickerNavigationController = [ABPeoplePickerNavigationController new];

        peoplePickerNavigationController.peoplePickerDelegate = self;

        peoplePickerNavigationController.predicateForSelectionOfPerson = [NSPredicate predicateWithFormat:@"phoneNumbers.@count == 1"];

        [controller presentViewController:peoplePickerNavigationController animated:YES completion:nil];

    }

然后实现各自的两个点击联系人的协议，就OK啦！
