Qt 5.3.2 / QML on iOS 8, cannot get UIView from QQuickWindow anymore [solved]

[nils_heidorn]

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 ?

Hi,

iOS 8 has brought a lot of modifications, you should bring this to the interest mailing list. You'll find there Qt's developers/maintainers. This forum is more user oriented.

Hello SGaist !
Thanks for the hint.

Are you talking of this list( sorry to be ignorant):
http://lists.qt-project.org/mailman/listinfo/interest

I don't want to spam the innocent with my problems :-)

Its solved !
The idiotic thing is: Xcode 6 Debugger showed uiview to be nil and so i thought the crash resulted from that, but in reality view WAS valid and the crash had another trivial reason...

There is no better debugging than fprintf... GRRR

:-)

Nice you found out !

qDebug ? :D

Since it's working now, please update the thread title prepending [solved] so other forum users may know a solution has been found :)

Hi all,

I'm trying to do the same thing but my compiler complains about incomplete type for QPlatformNativeInterface.

What do I need to do to use the code posted by nils?

Qt 5.3, iOS8

PS: SGaist you are the true master of Qt and iOS! Cheers for the great work, your answers have been guiding me a lot this year without you knowing it. :)

Hi !

Did you use the include:
#include <QtGui/qpa/qplatformnativeinterface.h>

Hi!

Thanks for the fast reply.

file doesn't exist...

[k.gaitanis]

Ask too fast and find yourself answering yourself...

for posterity :

QT += gui-private
