如何在 iPhone 通讯录中搜索特定电话号码？

我正在开发一个使用 bonjour 连接到另一部 iPhone 的应用程序。它的功能之一是当我连接到其他设备时，它会自动检查我是否有其他人的电话号码。所以我的问题是如何检查我的地址簿中其他设备提供的电话号码？

这是从我的地址簿方法之一中提取的示例。我没有通过电话号码进行搜索，但这让您知道如何继续满足您的需求：

- (void) scanAddressBookSample
    {
    NSUInteger i;
    NSUInteger k;

    ABAddressBookRef addressBook = ABAddressBookCreate();
    NSArray *people = (NSArray *) ABAddressBookCopyArrayOfAllPeople(addressBook);

    if ( people==nil )
        {
        NSLog(@"NO ADDRESS BOOK ENTRIES TO SCAN");
        CFRelease(addressBook);
        return;
        }

    for ( i=0; i<[people count]; i++ )
        {
        ABRecordRef person = (ABRecordRef)[people objectAtIndex:i];

        //
        // Phone Numbers
        //
        ABMutableMultiValueRef phoneNumbers = ABRecordCopyValue(person, kABPersonPhoneProperty);
        CFIndex phoneNumberCount = ABMultiValueGetCount( phoneNumbers );

        for ( k=0; k<phoneNumberCount; k++ )
            {
            CFStringRef phoneNumberLabel = ABMultiValueCopyLabelAtIndex( phoneNumbers, k );
            CFStringRef phoneNumberValue = ABMultiValueCopyValueAtIndex( phoneNumbers, k );
            CFStringRef phoneNumberLocalizedLabel = ABAddressBookCopyLocalizedLabel( phoneNumberLabel );    // converts "_$!<Work>!$_" to "work" and "_$!<Mobile>!$_" to "mobile"

            // Find the ones you want here
            //
            NSLog(@"-----PHONE ENTRY -> %@ : %@", phoneNumberLocalizedLabel, phoneNumberValue );

            CFRelease(phoneNumberLocalizedLabel);
            CFRelease(phoneNumberLabel);
            CFRelease(phoneNumberValue);
            }
        }

    [people release];
    CFRelease(addressBook);
    }
