如何处理 iPhone 通讯录上的多个属性？

问题是我总是在 phones 变量调用的任何方法中发生运行时崩溃。在此版本中，我在 1 (ABMultiValueCopyValueAtIndex) 处收到错误。如果我注释掉这一行，代码就会在 2 (ABMultiValueGetCount) 处崩溃。看来该房产已经空了。如果我 NSLog phones 变量。我得到(null)。我在 iPhone 模拟器上测试了代码，那里有一些虚拟联系人和一些电话号码。 firstName 和 lastName 也很有魅力。

for(id person in people){
    NSString *firstName = (NSString *)ABRecordCopyValue(person, kABPersonFirstNameProperty);
    NSString *lastName = (NSString *)ABRecordCopyValue(person, kABPersonLastNameProperty);
    ABMultiValueRef phones = ABRecordCopyValue(person, kABPersonPhoneProperty);
    NSString *phone = (NSString*)ABMultiValueCopyValueAtIndex(phones, 0); /*1*/
/*2/  id ph, phLb;
    for (CFIndex i = 0; i < ABMultiValueGetCount(phones); i++) {  
        phLb = ABMultiValueCopyLabelAtIndex(phones, i);
        ph = ABMultiValueCopyValueAtIndex(phones, i);
        NSLog(@"%@,%@", phLb, ph);
        CFRelease(phLb);
        CFRelease(ph);
    }
*/  
NSLog(@"%@", firstName);
NSLog(@"%@", lastName);
NSLog(@"%@", phones);
NSLog(@"%@", phone);

[firstName release];
[lastName release];
[phone release];
[phones release];

}

The problem is that I always get runtime crashes at any method invoked at phones variable.
At this version I get an error at 1 (ABMultiValueCopyValueAtIndex).
If I'll comment this line, the code crashes at 2 (ABMultiValueGetCount).
It looks like the property was empty. If I NSLog the phones variable. I get (null).
I test the code on iPhone Simulator, I have some dummy contacts there with some phone numbers.
Also firstName and lastName work like a charm.

for(id person in people){
    NSString *firstName = (NSString *)ABRecordCopyValue(person, kABPersonFirstNameProperty);
    NSString *lastName = (NSString *)ABRecordCopyValue(person, kABPersonLastNameProperty);
    ABMultiValueRef phones = ABRecordCopyValue(person, kABPersonPhoneProperty);
    NSString *phone = (NSString*)ABMultiValueCopyValueAtIndex(phones, 0); /*1*/
/*2/  id ph, phLb;
    for (CFIndex i = 0; i < ABMultiValueGetCount(phones); i++) {  
        phLb = ABMultiValueCopyLabelAtIndex(phones, i);
        ph = ABMultiValueCopyValueAtIndex(phones, i);
        NSLog(@"%@,%@", phLb, ph);
        CFRelease(phLb);
        CFRelease(ph);
    }
*/  
NSLog(@"%@", firstName);
NSLog(@"%@", lastName);
NSLog(@"%@", phones);
NSLog(@"%@", phone);

[firstName release];
[lastName release];
[phone release];
[phones release];

}

我认为您关于如何获取 ABMultiValueRef 的假设是错误的。我在这台计算机上没有方便的 AB 代码，但请验证 ABRecordCopyValue 是否是适当的方法。然后研究ABMultiValueRef如何访问其内容。它是一个与简单字符串完全不同的对象集。

代码：

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

释放地址簿，并且从地址簿引用的所有对象也被释放。因此，指向 MultiValueRefs 的指针在使用前已被释放。

The code:

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

deallocated the addressbook and all the objects that were reffered from it was released too. So the pointers to the MultiValueRefs were deallocated before use.
