After lunch app on iOS I see black screen.

  • Hi everyone!

    I'm using last Qt 5.8 RC1 on iOS platform. When I create new project in QtCreator and try to build it to real device or simulator I see black screen. In console I see this:

    Starting remote process.

    Screenshot from simulator.

    UPDATE: This bug happened only if I use QtCreator with iOS 10.x. But all works fine on iOS 9.x. Also this bug doesn't reproduce in Xcode. If I build my app for Xcode my project work fine on iOS 9.x and iOS 10.x.

    Which version of Qt Creator are you using ?

  • Thanks for the reply! I.m using QtCreator 4.2 from the official install package of Qt 5.8 RC1 which I download from official site.

    Can you retry with the official 5.8 release ?

  • Hi,

    I've been tested last release Qt 5,8 on iOS 10.2 Simulator and device. Now this but doesn't reproduce. But now I can't understand why my application can't find my QML plugin. I've check the path (Qt_install_dir)/ios/qml and see my plugin here. But when I try to load my app on device or simulator I've get message:

    QQmlApplicationEngine failed to load component
    qrc:/main.qml:5 module "com.shav.uicomponents" plugin "ShavUIComponents" not found

    But this happens only for iOS (on Android don't tested yet), on Mac OS all works fine.

    If you have plugins then set the QT_DEBUG_PLUGINS environment variable to 1 and check what the output says.

  • Hi,

    I'm trying this variable but can't see any results in debug console. I added it to Build Environment settings inside QtCreator for project. Is this correct? Or I need to add it another way?

    Anyway I created a new topic with this problem.

    I usually, put it in the Run part of the Project panel.
