Fancy Custom Transitions
summary
Shows concrete code and running demos: uses iOS7 transition APIs and the transitioning delegate protocols to implement a zoom, a dimmed core‑animation pop‑up, and an interactive cube 3D navigation pop. Uses UITransitionContext, UIViewControllerAnimatedTransitioning, UIViewControllerInteractiveTransitioning and a UIPercentDrivenInteractiveTransition subclass, keeps the transitionContext to drive progress, and puts code on GitHub (github com /g davis / Swift custom transitions). All three examples build and run, with cancelable interactive gestures that finish or rollback as expected.
