Qt 5.6 iOS geometry size ASSERT fail

douyw

Hi,
I'm encountering this weird problem on an iPhone 6s (ios 9.2) with Qt 5.6:

ASSERT: "m_qioswindow->geometry().size() == bounds" in file quiview.mm, line 183

My app simply cannot get started. The same app can be up and running on an iPad Mini(ios 8.2) without any problem. I wonder maybe the ios version matters, but I generated a new test app using QtCreator, it can run successfully on the iPhone.

I even downloaded the Qt 5.6 source code to see what happens in there, but can't get a clue. It's just an assert clause, left or right expression, which one goes mad? Still no idea.

If anyone has any idea about this, please reply. Thanks.

Hi and welcome to devnet,

What kind of application is ? QML ? Widgets ?

One way (not the easiest) is to disable everything from your application and re-add every piece one by one until your application breaks again.

I got the same error because i changed the window's geometry

window->setGeometry(window->screen()->geometry())

Hi and welcome to devnet,

Are you trying to modify the geometry of your main widget on iOS ?
