Problem displaying dialog boxes in AUv3s on iOS

If I call NativeMessageBox::showOkCancelBox in an AUv3 on iOS I get the following assertion →

        // Since iOS8, alert windows need to be associated with a window, so you need to
        // have at least one window on screen when you use this

I can fix it by adding the following line to the constructor of UIViewComponentPeer::UIViewComponentPeer:

iOSGlobals::currentlyFocusedPeer = this;

currentlyFocusedPeer is null when the plugin is instantiated until I edit a label or do something to change the focus, which is why I am getting the assertion.

Not sure if this is a bug that should be reported?
