Question

我试图访问姓名和号码电话簿并且都失败了几天。我使用以下代码，它在测试应用程序中成功运行，但是当我将它添加到您的项目工作中时，它不起作用。变量“grant”不断有一个值 - “false”，我得到错误“Access Failure”。尽管如此，在隐私设置中没有显示滑块以允许访问... 我一直找不到一个相当奇怪的行为的答案......

如果有任何帮助，我将不胜感激！`

如果您想访问地址簿中现有联系人的信息，请遵循以下代码：）

第1步：添加

#import <AddressBook/AddressBook.h>

第2步：从viewDidLoad

中调用方法

-(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.
}

第3步：也将此方法添加到您的代码中此方法为您提供特定联系人所需的所有信息。

- (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(@"=============================================");
            }

}

该应用程序无法访问电话簿
