于Symbian OS的通讯录操作总结

核心提示：TInt count = filter->iIds->Count();CleanupStack::PopAndDestroy(2); // filter contactsDb注：在某些symbian手机中，若没有设定DateTime可能会出现错误，于Symbian OS的通讯录操作总结(4)，6、数据库查询

TInt count = filter->iIds->Count();

CleanupStack::PopAndDestroy(2); // filter contactsDb

注：在某些symbian手机中，若没有设定DateTime可能会出现错误。

6、数据库查询

所用的函数有：

CContactDatabase::FindLC() ;

CContactDatabase::FindInTextDefLC();.

FindInTextDefLC() ;

FindInTextDefAsyncL();

例1、 FindInTextDefAsyncL()的应用：

iContactsDb = CContactDatabase::OpenL();

iFieldDef = new (ELeave)CContactItemFieldDef();

iFieldDef->AppendL(KUidContactFieldGivenName);

iFieldDef->AppendL(KUidContactFieldFamilyName);

_LIT(KFindToken, "Bond");

iFinder =

iContactsDb->FindAsyncL( KFindToken, iFieldDef, this);

if(iFinder->IsComplete())

{

if(iFinder->Error() == KErrNone)

{

CContactIdArray* result = iFinder->TakeContactIds();

for(TInt i=0; iCount(); i++)

{

TInt cardId = (*result)[i];

// do something with the card

}

delete result;

}

delete iFinder;

delete iFieldDef;

delete iContactsDb;

}
