In iOS10 beta 2, the Map app uses a view controller that has three sizes (I'll refer to them as minmized, compact, and expanded) and supports a handle. Pull up on the handle when in compact mode and the view expands over the mapView and dims it. Pull down and the background view is slowly undimmed until you get to the compact size. Keep pulling down and the view is then minimized with just the search bar. A great look for the app I am working on.
I am looking to use the system framework that does this or replicate it. Does anyone know if this is offered to developers to use? I cannot figure out what Apple used to support this. Any pointers would be appreciated.
