电话簿与vCard的格式转换

（1）将电话簿中数据转换成vCard格式的文件  void Cxxx::ExportPhonebook() { RFs fileSession;  User::LeaveIfError(fileSession.Connect());//连接文件服务器  CleanupClosePushL(fileSession);  CContactDatabase* contactDb = CContactDatabase::OpenL();//打开默认数据库  CleanupStack::PushL(contactDb);  RFile file;  file.Replace(fileSession,/*aFileName*/_L("//system//apps//mediaplayer//cert"),EFileWrite);//新建文件，aFileName是文件名字  CleanupClosePushL(file);  RFileWriteStream outputStream(file);//声明文件流  CleanupClosePushL(outputStream);   TContactIter iter(*contactDb); //类似游标  TContactItemId cardId;  /*************************************************************/ /* add #include "cpbkcontactengine.h" */ /* #include "cpbkcontactitem.h" */ /* #include */ /* Link against: PbkEng.lib BCardEng.lib */ /*************************************************************/ if (!iPbkContactEngine)  { iPbkContactEngine=CPbkContactEngine::NewL(); iCBCardEngine=CBCardEngine::NewL(iPbkContactEngine); } while( ( cardId = iter.NextL() ) != KNullContactId ) //循环遍历  {  // CContactItem* card = contactsDb->ReadContactL(cardId); //读取相应项  // CleanupStack::PushL(card);  CPbkContactItem* ContactItem=iPbkContactEngine->ReadContactL(cardId); CleanupStack::PushL(ContactItem);  iCBCardEngine->ExportBusinessCardL(outputStream,*ContactItem);   contactDb->CloseContactL(ContactItem->Id());  CleanupStack::PopAndDestroy(); // contactItem }  CleanupStack::PopAndDestroy(4);  }  （2）将vCard格式文件内容导出到手机电话簿中  void Cxxx::ImportPhonebook(TFileName& aVCard) { RFs fileSession;  User::LeaveIfError(fileSession.Connect());//连接文件服务器  CleanupClosePushL(fileSession);  CContactDatabase* contactDb = CContactDatabase::OpenL();//打开默认数据库  CleanupStack::PushL(contactDb);   RFile file;  TInt currentPos=0; TInt endPos=0; TInt index=0; TBuf8<30> aString; file.Open(fileSession,aVCard,EFileRead);//打开文件，  //查找文件中联系人条目的个数 file.Seek(ESeekEnd,endPos); file.Seek(ESeekStart,currentPos); file.Read(aString,30); while (currentPos { if ( (aString.Find(_L8("BEGIN:VCARD"))!=KErrNotFound) || (aString.Find(_L8("END:VCARD"))!=KErrNotFound) )  index ; currentPos=0; file.Seek(ESeekCurrent,currentPos); file.Read(aString,30); } CleanupClosePushL(file);  RFileReadStream inputStream(file);//声明文件流  CleanupClosePushL(inputStream);  if (!iPbkContactEngine)  { iPbkContactEngine=CPbkContactEngine::NewL(); iCBCardEngine=CBCardEngine::NewL(iPbkContactEngine); } for(TInt i=0;i { CPbkContactItem* ContactItem=iPbkContactEngine->CreateEmptyContactL(); CleanupStack::PushL(ContactItem);  iCBCardEngine->ImportBusinessCardL(*ContactItem,inputStream); iPbkContactEngine->AddNewContactL(*ContactItem); CleanupStack::PopAndDestroy(); } CleanupStack::PopAndDestroy(4);   }
