What iphone app lets you play Youtube on TV through connecting cord?

I use to use the iphone to show my students youtube videos but now with ios6 installed the iphone 4s does not work for showing it on TV. Are there any other apps for iphones that will have video out for Youtube… Even the official Youtube app does not have it.
