objective-c - 如何从地址簿中获取电话号码作为字符串？

Question

我有一个包含联系人姓名的文本字段，我想获取该联系人的电话号码:

ABAddressBookRef adressBook = ABAddressBookCreate();

NSArray *people = (NSArray *)ABAddressBookCopyPeopleWithName(adressBook,
                               CFStringCreateCopy(kCFAllocatorDefault, 
                                                 (CFStringRef)recipient));

if((people != nil) && ([people count] == 1)){
    ABMultiValueRef person = (ABMultiValueRef)[people objectAtIndex:0];
    NSString *phone = (NSString *)ABRecordCopyValue(person, 
                                                      kABPersonPhoneProperty) ;
    NSLog(@"%@", phone);
}

我想要电话号码作为字符串，但这给了我更多:

ABMultiValueRef 0x339470 with 1 value(s)
    0: _$!<Mobile>!$_ (0x338c50) - 0177 1647788 (0x339450)

如何只获取字符串形式的数字？

Answer 1

NSMutableArray *phoneNumbers = [[[NSMutableArray alloc] init] autorelease];
ABMultiValueRef multiPhones = ABRecordCopyValue(person,kABPersonPhoneProperty);
for(CFIndex i=0;i<ABMultiValueGetCount(multiPhones);++i) {
    CFStringRef phoneNumberRef = ABMultiValueCopyValueAtIndex(multiPhones, i);
    NSString *phoneNumber = (NSString *) phoneNumberRef;

    [phoneNumbers addObject:phoneNumber];
}
