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.

@bogong For me it's normal develop qt (also for mobile application), but in this time I must develop a strange case, I must use a native controller (that it can't be emulate in qt/qml) and from this I must start the qml GUI. It's all ok, I see the qml elements but I can't catch the user interaction, not press button, nothing. I started from Qt project where I added native object-c files, AppDelegate, other native controller, etc.

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.

@Almer_Cz said: ...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
