QProgressDialog does not show as correct size in iOS

CellCS

QQmlEngine::setObjectOwnership(quit_loop, QQmlEngine::CppOwnership);
QProgressDialog progress(("Loading Data------------"), QString(), 0, 100);

......(signals)

progress.setRange(0,0);

int progressCode = progress.exec();

In Android, works fine and progress dialog show default size, and resize() functions works. But in iOS, show in the whole screen, and resize() does not work. But when using progress.size(), get QSize(220, 64).

how could show progressbar Dialog correctly. Thanks
