[SOLVED] Problem with iOS app and QML Plugin.

shav

Hi everyone!

I have a project with QML plugin. On desktop all works fine but when I try to build my application to iOS i've received this error:
@
Starting remote process.
QML debugging is enabled. Only use this in a safe environment.
QQmlApplicationEngine failed to load component
qrc:/qml/ios/main.qml:1 static plugin for module "QtQuick" with name "PicfectionSDKPlugin" has no metadata URI
@

My qmldir file looks like:
@
module com.shav.picfection
plugin PicfectionSDK
typeinfo Picfection.qmltypes
classname PicfectionSDKPlugin
@

My plugin was copied to:
@
<Qt_install_path>/ios/qml/com/shav/picfection
@

What I do wrong? Thanks for any help!

Hi everyone!

I still have problem with QtQuick Plugin on iOS. I've tried research but can't find any solution for this problem. Also I've tried examples but no lucky. Main class of my plugin looks like this:
@
class PicfectionSDKPlugin : public QQmlExtensionPlugin
{
Q_OBJECT

    Q_PLUGIN_METADATA(IID "org.qt-project.Qt.QQmlExtensionInterface")

public:
    void registerTypes(const char *uri);

};
@

Project file of my plugin looks like:
@
TEMPLATE = lib
TARGET = PicfectionSDK
QT += qml quick network
ios {
CONFIG += qt plugin c++11 static
}
else
{
CONFIG += qt plugin c++11
}

TARGET = $$qtLibraryTarget($$TARGET)
uri = com.shav.picfection

DESTDIR = com/shav/picfection
OBJECTS_DIR = tmp/objects
MOC_DIR = tmp/mocs

Default rules for deployment.

I can't understand how to fix problem with metadata URI. Could you help me with this?

Hi, everyone!

Maybe somebody know where I can find information about metadata URI for iOS QML plugins?

shav

Hi everyone!

At last I found the solution of my problem with static plugin for iOS. The solution is: set line to your plugin .pro file
@
QMAKE_MOC_OPTIONS += -Muri=com.shav.picfection
@

and you plugin .pro file must looks like:

TEMPLATE = lib
TARGET = PicfectionSDK
QT += qml quick network
ios {
	CONFIG += qt plugin c++11 static
}
else
{
	CONFIG += qt plugin c++11
}

TARGET = $qtLibraryTarget($TARGET)
uri = com.shav.picfection
QMAKE_MOC_OPTIONS += -Muri=com.shav.picfection #<----- This helped me to solve my problem.
