No, but I've done other platform-specific tie-ins for OSX/Android without problem. I create a class (Derived from QObject) that is the shim for each platform. Then in a .mm file I add the obj-c code. Because my app is QML, I expose it as a root context property. 

	PlatformShimImpl *shim = new PlatformShimImpl(&app);
	engine.rootContext()->setContextProperty(QStringLiteral("platformShim"), shim);
	app.connect(&app, SIGNAL(applicationStateChanged(Qt::ApplicationState)), shim, SLOT(applicationStateChanged(Qt::ApplicationState)));

I would expect the same to work for services.
