請尊重原創，謝謝！

iOS8及以前的通訊錄框架是AddressBookUI
9之後改了ContactsUI
代碼如下：

#import <AddressBookUI/ABPeoplePickerNavigationController.h>
#import <ContactsUI/CNContactPickerViewController.h>
#import <AddressBook/AddressBook.h>
#import <Contacts/Contacts.h>

if ([[UIDevice currentDevice].systemVersion floatValue] >= 9.0) {
         CNContactPickerViewController *picker=[[CNContactPickerViewController alloc]init];
         picker.delegate=self;
         [self.h5ViewController presentViewController:picker animated:YES completion:NULL];
     }
    else
    {
        ABPeoplePickerNavigationController *picker = [[ABPeoplePickerNavigationController alloc] init];
        picker.peoplePickerDelegate = self;
        [self.h5ViewController presentViewController:picker animated:YES completion:NULL];
    }

其中如果實現了- (void)contactPicker:(CNContactPickerViewController *)picker didSelectContacts:(NSArray<CNContact*> *)contacts
或者- (void)contactPicker:(CNContactPickerViewController *)picker didSelectContactProperties:(NSArray<CNContactProperty*> *)contactProperties
就會默認通訊錄多選，所以如果想要pickerView展現的是單選，就不要實現這兩個delegate協議方法即可。
