[Interest] Debug messages to socket on iOS

[Jason H]

I want to add logging of all messages that appear in the application output pane of QtC. For non-QML this can be gone by qInstallMessageHandler() but I am not having success on iOS.
I install it in the usual way in main():

qInstallMessageHandler(myiOSMessageOutput);

Even though I have an empty one (doesn't printf or fprintf anything), I still get messages. Not sure what is going on? What am I missing?
