如何打开特定联系人的编辑联系人屏幕

Question

我正在iOS应用程序中，我必须在add中使用Address Book个联系人。

我想在用户尝试添加Edit联系人时打开duplicate联系人屏幕。

但是我不知道该怎么做。目前我只能显示一条消息。

我将所有联系人列表都设为：

 NSArray *allContacts = (__bridge NSArray *)ABAddressBookCopyArrayOfAllPeople(addressBookRef);

然后，我要遍历并检查是否存在。如果存在，则显示一条消息，否则我将其添加到通讯簿中。

     for (id record in allContacts){
    ABRecordRef thisContact = (__bridge ABRecordRef)record;
    if (CFStringCompare(ABRecordCopyCompositeName(thisContact),
                        ABRecordCopyCompositeName(pet), 0) == kCFCompareEqualTo){
        //The contact already exists!
        NSLog(@"contact exosts");
    }
    else
    {
        ABAddressBookAddRecord(addressBookRef, pet, nil);
        ABAddressBookSave(addressBookRef, nil);
          ABMultiValueAddValueAndLabel(phoneNumbers, (__bridge CFStringRef)petPhoneNumber, kABPersonPhoneMainLabel, NULL);
        NSLog(@"contacts Added");
    }
}

当用户尝试添加重复的联系人时，如何打开以下屏幕：

请参见.h

#import <AddressBook/AddressBook.h>
#import <AddressBookUI/AddressBookUI.h>

@interface ContactsViewController : UIViewController <UITableViewDataSource, UITableViewDelegate, ABPersonViewControllerDelegate>
{
    IBOutlet UITableView *tblContacts;
    NSMutableArray *arrContacts;
}
@end

和.m

#import "ContactsViewController.h"

@interface ContactsViewController ()
{
    UIAlertController *action;
}
@end

@implementation ContactsViewController

Answer 2

您可以按以下方式编辑联系人

这里您必须添加

// ------- Deprecated (in iOS 9.0)

#import <AddressBook/AddressBook.h>
#import <AddressBookUI/AddressBookUI.h>

ABPersonViewController *personController = [[ABPersonViewController alloc] init];
personController.personViewDelegate = self;
personController.displayedPerson = (__bridge ABRecordRef)arrContacts[indexPath.row];
personController.allowsEditing = YES;
personController.allowsActions = YES;
[self.navigationController pushViewController:personController animated:TRUE];

还有这里

#import <Contacts/Contacts.h>
#import <ContactsUI/ContactsUI.h>

// -------- This is not working for me, I got error
CNContact *contact = [arrContacts objectAtIndex:indexPath.row];
NSArray *keys = @[CNContactIdentifierKey, CNContactEmailAddressesKey, CNContactBirthdayKey, CNContactImageDataKey, CNContactPhoneNumbersKey, [CNContactFormatter descriptorForRequiredKeysForStyle:CNContactFormatterStyleFullName]];
CNContactViewController *contactController = [CNContactViewController viewControllerForContact:contact];
contactController.delegate = self;
contactController.allowsEditing = YES;
contactController.allowsActions = YES;
contactController.displayedPropertyKeys = keys;
[self.navigationController pushViewController:contactController animated:TRUE];

请参见Contact is missing some of the required key descriptors in ios

但是我仍然没有找到解决方法，如果有请告诉我

Answer 3

这里是答案当您绑定arrayOfContact时，您必须在[CNContactViewController descriptorForRequiredKeys]中提供密钥。

NSArray *keys = @[CNContactGivenNameKey,CNContactFamilyNameKey,CNContactOrganizationNameKey, CNContactPhoneNumbersKey, CNContactEmailAddressesKey,CNContactPostalAddressesKey,[CNContactViewController descriptorForRequiredKeys]]
CNContactFetchRequest *request = [[CNContactFetchRequest alloc] initWithKeysToFetch:keys];
