Wireless DJ on IOS

I have been experimenting with MIDI DJ on my IPhone, using it to control Mixxx on my PC. I have all the buttons and sliders working as well as outputs for button LEDS etc. However I cannot find any examples of code to allow me to output data to display track title and track time on my iphone app/MIDI controller. The app has the capability to display these things.
Has anybody done this.

Cheers
Rod

This is currently not possible. Mixxx does not give this information to controllers (One can only obtain numeric values, not textual values)

Thanks for clearing that up. I was starting to think that may be the case.
