Deploy Sqlite db file on iOS and Winphone?

AlekseyShi

Code below it works on Android, but how to do same on iOS and Winphone?

QFile dfile("assets:/db/database-last.db3");
if (dfile.exists())
{
    dfile.copy("./database-last.db3");
    QFile::setPermissions("./database-last.db3",QFile::WriteOwner |     QFile::ReadOwner);
 }

...

QSqlDatabase db = QSqlDatabase::addDatabase("QSQLITE");
db.setDatabaseName("./database-last.db3");
db.open();

...

in .pro file

deployment.files += database-last.db3
deployment.path = /assets/db
INSTALLS += deployment

@AlekseyShi Here you try to write in current directory:

dfile.copy("./database-last.db3");

This not going to work then that directory isn't writeable by your application (and the installation directory of an mobile app isn't writable!).
You should use one of the standard directories from http://doc.qt.io/qt-5/qstandardpaths.html (QStandardPaths::AppDataLocation)

It works on Android by set permissions. My question is for iOS and Winphone concerning to pack dbfile into *.dmg.
*But I'll try your advice too. :)
