系统错误 -23
查了下，好像是读写错误，小弟在网上弄了段简单的添加通讯录的代码，如下。编译是没有问题的，但运行的时候出现上述系统错误，求解决方法
{
CPbkContactEngine * engine = CPbkContactEngine::NewL();
CleanupStack::PushL(engine);
CPbkContactItem* contact = engine->CreateEmptyContactL();
CleanupStack::PushL(contact);
_LIT(KFName,"King");
_LIT(KLName,"Chai");
_LIT(KNumber,"13777777777");
_LIT(KText,"the name has been added");
//修改first name
TPbkContactItemField* field = contact->FindField(EPbkFieldIdFirstName);
CPbkFieldInfo* fieldInfo;
field->TextStorage()->SetTextL(KFName);
field = contact->FindField(EPbkFieldIdLastName);
field->TextStorage()->SetTextL(KLName);
field = contact->FindField(EPbkFieldIdPhoneNumberMobile);
field->TextStorage()->SetTextL(KNumber);
TContactItemId Id = engine->AddNewContactL(*contact);
ShowNoteL(KText);
CleanupStack::PopAndDestroy(contact);
CleanupStack::PopAndDestroy(engine);
}
[解决办法]
代码看不出问题来，是不是少能力？
