创建ini文件：

void CFrozenBubbleAppUi::WriteIniFile(TUid iInfo, void *ptr, TUint size){

TInt r;

RFs fs;

fs.Connect();

CleanupClosePushL( fs );

RDictionaryWriteStream rdsIniFile;

CDictionaryStore *cdIniFile = Application()->OpenIniFileLC(fs);//如果不存在就创建

rdsIniFile.AssignLC(*cdIniFile, iInfo);

TPtr8 buf((TUint8*)ptr, size, size);

TRAP(r, rdsIniFile.WriteL(buf));

rdsIniFile.CommitL();

CleanupStack::PopAndDestroy();

cdIniFile->CommitL();

CleanupStack::PopAndDestroy( 2 );

}

读ini文件：

TBool CFrozenBubbleAppUi::ReadIniFile(TUid iInfo, void *ptr, TUint &size){

TInt r;

TBool result = EFalse;

RFs fs;

fs.Connect();

CleanupClosePushL( fs );

RDictionaryReadStream rdsIniFile;

CDictionaryStore *cdIniFile = Application()->OpenIniFileLC(fs);

if (cdIniFile->IsPresentL(iInfo)){

rdsIniFile.OpenLC(*cdIniFile, iInfo);

TPtr8 buf((TUint8*)ptr, size);

TRAP(r, rdsIniFile.ReadL(buf));

CleanupStack::PopAndDestroy(); // rdsIniFile

result = ETrue;

}

CleanupStack::PopAndDestroy( 2 ); // fs, cdIniFile

return result;

}
