[Interest] iOS8: Qt 5.3.2 / QML , cannot get UIView from QQuickWindow anymore

[Gustavsen Richard]

The iOS version should not matter in this case (with respect to how this is implemented in Qt). But since you try to get the view, you are mixing Qt with native APIs. Do you call UIApplicationMain yourself? Perhaps you try to grab the view at a point before the window is fully created? You can check if reinterpret_cast<UIView *>(window()->winId()) returns the view. Otherwise you must be doing something very strange...

Emne: [Interest] iOS8: Qt 5.3.2 / QML , cannot get UIView from QQuickWindow anymore

Hi !

I got a problem since upgrading my iPad to iOS 8 (had to, customer wants
me to continue developing on iOS8 NOW).

On iOS 7.x i was used to get the current uiview like this:

UIView *view = static_cast<UIView
*>(QGuiApplication::platformNativeInterface()->nativeResourceForWindow("uiview",
window()));


or if i want to have it “ARC safe”:

UIView *view = (__bridge UIView *)reinterpret_cast<void
*>(QGuiApplication::platformNativeInterface()->nativeResourceForWindow("uiview",
window()));


But on iOS8 this results in “view = nil” :-(

I need the uiview in order to get the UIViewController (as most will):

UIViewController *qtController = [[view window] rootViewController];


Sooo, do you know a way to get the uiview (or better the
UIViewController) on iOS 8 ?

Greetings,

Nils
