名前と番号の電話帳にアクセスしようとして数日間苦しんでいますが、すべて失敗しました。テスト アプリケーションでは正常に動作する次のコードを使用しますが、プロジェクト作業に追加すると動作しません。変数 "granted" には常に "false" という値があり、"Access Failure" というエラーが発生します。それにもかかわらず、プライバシー設定では、アクセスを許可するスライダーが表示されません...私は長い間、かなり奇妙な動作に対する答えを見つけることができませんでした...

どんな助けにも感謝します！

CNContactStore *store = [[CNContactStore alloc] init];
[store requestAccessForEntityType:CNEntityTypeContacts completionHandler:^(BOOL granted, NSError * _Nullable error) {
    if (granted == YES) {

        NSMutableArray *contacts = [NSMutableArray array];

        NSArray *keys = @[CNContactFamilyNameKey, CNContactGivenNameKey, CNContactPhoneNumbersKey, CNContactImageDataKey];
        NSString *containerId = store.defaultContainerIdentifier;
        NSPredicate *predicate = [CNContact predicateForContactsInContainerWithIdentifier:containerId];
        NSError *error;
        NSArray *cnContacts = [store unifiedContactsMatchingPredicate:predicate keysToFetch:keys error:&error];
        if (error) {
            NSLog(@"error fetching contacts %@", error);
        } else {
            for (CNContact *contact in cnContacts) {

                TSContact *newContact = [[TSContact alloc] init];
                newContact.firstName = contact.givenName;
                newContact.lastName = contact.familyName;
                UIImage *image = [UIImage imageWithData:contact.imageData];
                newContact.image = image;
                for (CNLabeledValue *label in contact.phoneNumbers) {
                    NSString *phone = [label.value stringValue];
                    if ([phone length] > 0) {
                        [contacts addObject:phone];
                    }
                }
            }
        }
    } else {
        NSLog(@"Error = %@", error.localizedDescription);
    }
}];

アドレス帳にある既存の連絡先の情報にアクセスしたい場合は、次のコードが役立ちます:)

ステップ 1 : 追加

#import <AddressBook/AddressBook.h>

ステップ 2 : viewDidLoad から次のメソッドを呼び出す

-(void)phonenumber
{
    self.navigationController.navigationBarHidden = true;
    ABAuthorizationStatus status = ABAddressBookGetAuthorizationStatus();

    if (status == kABAuthorizationStatusDenied || status == kABAuthorizationStatusRestricted) {
        // if you got here, user had previously denied/revoked permission for your
        // app to access the contacts, and all you can do is handle this gracefully,
        // perhaps telling the user that they have to go to settings to grant access
        // to contacts

        [[[UIAlertView alloc] initWithTitle:nil message:@"This app requires access to your contacts to function properly. Please visit to the \"Privacy\" section in the iPhone Settings app." delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil] show];
        return;
    }

    CFErrorRef error = NULL;
    ABAddressBookRef addressBook = ABAddressBookCreateWithOptions(NULL, &error);

    if (!addressBook) {
        NSLog(@"ABAddressBookCreateWithOptions error: %@", CFBridgingRelease(error));
        return;
    }

    ABAddressBookRequestAccessWithCompletion(addressBook, ^(bool granted, CFErrorRef error) {
        if (error) {
            NSLog(@"ABAddressBookRequestAccessWithCompletion error: %@", CFBridgingRelease(error));
        }

        if (granted) {
            // if they gave you permission, then just carry on
            [self listPeopleInAddressBook:addressBook];
        } else {
            // however, if they didn't give you permission, handle it gracefully, for example...
            dispatch_async(dispatch_get_main_queue(), ^{
                // BTW, this is not on the main thread, so dispatch UI updates back to the main queue
                [[[UIAlertView alloc] initWithTitle:nil message:@"This app requires access to your contacts to function properly. Please visit to the \"Privacy\" section in the iPhone Settings app." delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil] show];
            });
        }
        CFRelease(addressBook);
    });
    // Do any additional setup after loading the view.
}

ステップ 3 :このメソッドをコードにも追加する このメソッドは、特定の連絡先に必要なすべての情報を提供します。

- (void)listPeopleInAddressBook:(ABAddressBookRef)addressBook
{
            //Run UI Updates
            NSArray *allPeople = CFBridgingRelease(ABAddressBookCopyArrayOfAllPeople(addressBook));
            NSInteger numberOfPeople = [allPeople count];

            for (NSInteger i = 0; i < numberOfPeople; i++) {
                ABRecordRef person = (__bridge ABRecordRef)allPeople[i];
                //From Below code you can get what you want.
                NSString *firstName = CFBridgingRelease(ABRecordCopyValue(person, kABPersonFirstNameProperty));
                NSString *lastName  = CFBridgingRelease(ABRecordCopyValue(person, kABPersonLastNameProperty));
                NSLog(@"Name:%@ %@", firstName, lastName);

                ABMultiValueRef phoneNumbers = ABRecordCopyValue(person, kABPersonPhoneProperty);
                NSString *phoneNumber = CFBridgingRelease(ABMultiValueCopyValueAtIndex(phoneNumbers, 0));
                NSLog(@"phone:%@", phoneNumber);
                NSLog(@"=============================================");
            }

}
