I did not find any method to dismiss date pickers.
In my opinion, this would be a quite useful feature, looking at the following example:
User selects date range for a search query:
Navigation controller pushes to results controller:
User hits 'Back', is confronted with a half-screen date picker --> Bad UX:
Does anyone know how to solve the problem with already available methods?
I plan on fixing this soon on this Issue #377. Thanks!
