I’m opening this in the Issue category.
See here : Does animation="nav-title-slide-ios7" still work?
I don’t think nav-title-slide-ios7 works anymore.
See this Codepen that should demonstrate it: http://codepen.io/ionic/pen/HjnFx
Thanks @Calendee, I’ve noticed this too. A fix for this should be in soon (https://github.com/driftyco/ionic/pull/607)
