you have to setGeometry(QRect screenGeometry) explicitly. screenGeometry should be queried from iOS directly, like this:

const CGRect r = [[UIScreen mainScreen] bounds];
return QRect(0, 0, r.size.width, r.size.height);

We had similar problem, black screen with AirPlay or with HDMI dongle. This solved it for us.
