Loren Brichter implemented the "pull-down to refresh" mechanism in Tweetie 2, and Tweetie 1 already has a similar prototype (a button instead of a direct pull-down trigger operation). The pull-to-refresh operation was first invented by Loren Brichter, the founder of Tweetie.
After that, many mobile clients based on news feeds successively adopted this design, and now it has basically become the standard for similar mobile applications.
Loren Brichter applied for a patent for "Pull-down to Refresh", but he would like to see this mechanism adopted by other apps, and has also said that the application is defensive.
Tweetie is a third-party Twitter client that was later acquired by Twitter, and Loren Brichter also became a Twitter employee (now gone).
Pull down to refresh:
It has been widely used in various applications. Sparrow, Facebook, Sina Weibo, and even iOS native systems are also using this method. . Some theories believe that pull-down refresh is an application suitable for arranging feeds in chronological order from new to old. In this application scenario, after viewing old content, users will naturally pull down to find newer content.
So pull-down refresh seems very reasonable. With the continuous evolution of the pull-down refresh method, pull-down refresh has jumped out of the basic function and become an element that expresses brand and design sense. This article mainly introduces several interesting pull-down refresh methods.
During the collection process, we found that some applications cleverly integrate application types into pull-down refresh; the pull-down refresh of many applications incorporates brand elements, including the color of the logo, the shape of the icon, etc. etc. There are also some that are more special and have some innovations combined with the style of the entire application.
