ABAddressBookSave（...）iOS 4.3上的EXC_BAD_ACCESS

Question

我遇到问题我的应用程序崩溃试图保存通讯簿。崩溃是由EXC_BAD_ACCESS造成的，并且由于呼叫ABCDBContextSaveMultiValue

而在CFArrayGetCount(...)期间发生

因此，我认为我已经解决了问题，但不知道如何解决它。这是我的代码：

ABAddressBookRef addressBook = ABAddressBookCreate();

for (int i=0; i<[pledgeInfo count]; i++ ) {
    NSArray * pledgeObj = [pledgeInfo objectAtIndex:i];
    ABRecordRef personRef = ABPersonCreate();
    CFErrorRef error = NULL;
    if( !ABRecordSetValue(personRef, kABPersonFirstNameProperty, [pledgeObj objectAtIndex:1], &error) ) {/*ErrorHandle*/}
    if( !ABRecordSetValue(personRef, kABPersonLastNameProperty, [pledgeObj objectAtIndex:2], &error) ) {/*ErrorHandle*/}
    if( !ABRecordSetValue(personRef, kABPersonEmailProperty, [pledgeObj objectAtIndex:4], &error) ) {/*ErrorHandle*/}

    // ERROR IS IN HERE SOMEWHERE
    ABMutableMultiValueRef phNums = ABMultiValueCreateMutable(kABMultiStringPropertyType);
    ABMultiValueIdentifier abi;
    if( !ABMultiValueAddValueAndLabel(phNums, [pledgeObj objectAtIndex:3], kABPersonPhoneMobileLabel, &abi) ) {/*ErrorHandle*/}
    if( !ABRecordSetValue(personRef, kABPersonPhoneProperty, phNums, &error) ) {/*ErrorHandle*/}
    if( !ABAddressBookAddRecord(addressBook, personRef, &error) ) {/*ErrorHandle*/}
}
    NSLog(@"%@",addressBook);
    CFErrorRef cferr = NULL;
    if( !ABAddressBookSave(addressBook, &cferr) ) {/*ErrorHandle*/
}
