How does pull-to-refresh work?
Pull-to-refresh is a touchscreen gesture that consists of touching the screen of a computing device with a finger or pressing a button on a pointing device, dragging the screen downward with the finger or pointing device, and then releasing it, as a signal to the application to refresh the contents of the screen.
Who invented pull-to-refresh?
Twitter was just officially granted a patent on the ubiquitous pull-to-refresh gesture — a touch interface concept the company acquired when it purchased Tweetie developer Atebits in 2010 and hired founder Loren Brichter, who invented the move.
