iphone - 执行 ABAddressBookSave 时 EXC_BAD_ACCESS !

Question

我正在尝试创建一个新联系人并将其添加到地址簿中，但是当我到达 ABAddressSave 代码行时，我得到了 EXC_BAD_ACCESS。我看不出我做错了什么，我启用了 NSZombie 来检查这是否是与内存相关的错误，但它没有发现任何错误。谁能告诉我这段代码有什么问题吗？预先感谢您!

    CFErrorRef error = NULL;

 ABAddressBookRef iPhoneAddressBook = ABAddressBookCreate();

 ABRecordRef newRecord = ABPersonCreate();

 ABRecordSetValue(newRecord, kABPersonFirstNameProperty, @"Xxxxxx", &error);

 ABRecordSetValue(newRecord, kABPersonURLProperty,  @"Yyyyyy", &error);


 //Add phone numbers to record

 ABMutableMultiValueRef phones = ABMultiValueCreateMutable(kABMultiStringPropertyType);
 ABMultiValueAddValueAndLabel(phones, @"1-555-555-5555", kABWorkLabel, NULL);


 ABRecordSetValue(newRecord, kABPersonPhoneProperty, phones, &error);

 CFRelease(phones);

 //Add email address to record

 ABMutableMultiValueRef emails = ABMultiValueCreateMutable(kABMultiStringPropertyType);
 ABMultiValueAddValueAndLabel(emails, @"xxx_xxx@yahoo.com", kABWorkLabel, NULL);


 ABRecordSetValue(newRecord, kABPersonEmailProperty, emails, &error);

 CFRelease(emails);

 ABMutableMultiValueRef multiAddress = ABMultiValueCreateMutable(kABMultiDictionaryPropertyType);

 NSMutableDictionary *addressDict = [[NSMutableDictionary alloc] init];

 [addressDict setObject:@"xxx1" forKey:(NSString *)kABPersonAddressStreetKey];
 [addressDict setObject:@"xxx2" forKey:(NSString *)kABPersonAddressCityKey];
 [addressDict setObject:@"xxx3" forKey:(NSString *)kABPersonAddressStateKey];
 [addressDict setObject:@"xxx4" forKey:(NSString *)kABPersonAddressZIPKey];

 ABMultiValueAddValueAndLabel(multiAddress, addressDict,  kABWorkLabel, NULL);


 ABRecordSetValue(newRecord, kABPersonAddressProperty, multiAddress, &error);

 CFRelease(multiAddress);
 [addressDict release];


 ABAddressBookAddRecord(iPhoneAddressBook, newRecord, &error);
 ABAddressBookSave(iPhoneAddressBook, NULL);

 if(error != nil){
  NSLog(@"Error creating contact:%@", error);
 }

我建议使用 Memory->Object Allocations 模板在 Instruments 中运行代码。它应该很快地告诉您哪个对象有问题以及什么内存释放导致了问题。
