Ok, the problem solved itself with update to Qt 5.11.2 (while running iOS12). Thanks for reading.

Here is the code that works:

QString path = QCoreApplication::applicationDirPath() + "/Photo 2014-05-10 11 33 08.jpg"; QPixmap pixmap(path); ui->label->setPixmap(pixmap);

Right, I forgot there was the tech preview. So indeed you can grab Qt 5.8.

Hi all.
I'd rather raise this old topic, than create an identical one.
I'm trying to achieve exactly the same functionality using iOS12 (since yesterday) and Qt 5.10.1 (more recent versions are to be tested yet). It does not work. No updates, no events are coming to my Qt window, and it's not being drawn. Does anyone has a working solution?

I have gone through following resources without success:
https://github.com/msorvig/qt-and-swift
https://forum.qt.io/topic/65979/calling-qt-gui-from-native-ios-gui-vice-versa
https://alediaferia.com/2014/12/18/a-native-ios-app-with-a-qt-third-party-library/
https://github.com/richardmg/HybridQtIosApp/tree/master/HybridQtApp

p.s. I will post sample code a bit later.

Thanks in advance!

Am I the only one having this problem?

@NGV1
seems like the app is crashing for them. So the reason is to figure out why.
Don't they provide a stack trace of the crash?

Also you can try to upgrade the used Qt version, since a lot of stuff happens during major releases especially in the mobile section.

@SGaist Ohh cool ! Didn't know about that feature.. Thank you :)

Did you generate the Xcode project using qmake ?

Hi and welcome to devnet,

Did you regenerate the Xcode project after deleting Xcode 6.4 ?

This is a very useful set of formatter... My problem is that the formatters works only once in a while. Sometimes I have to start XCode 7.2 several times to make it work. And as soon as I restart the debugger, the formatters don't work anymore. This sounds more like a LLDB bug than a bug from your formatters, I must say...

Solved by upgrading Qt Creator to 3.5.0
Many thanks.

...and also create .pro and let qmake to generate XCode project, but this will produce a lot of Mambo Jambo around and won't be handy when something changes.

So your looking for a way to create and maintain the Mambo Jambo manually and this will somehow be more handy ?

I'd generate the Xcode project from a .pro file, that way you have everything setup for you

Sorry, I don't know OpenGL well enough to propose you an alternative/workaround to emulate that behavior.

Hi,

Out of curiosity, can you describe what your application does that it needs all of these elements hidden ?

Hi and welcome to devnet,

What version of Qt are you using ? What exact error message did you get ?

Thanks anyway Sandy. This is a weird one to be sure.

Hi,
I deleted the whole build directory. Than I created a new release with QtCreator and opened the xcode project in xcode (there i also tried a clean and build).
best,
Patrik
