Are there any 3rd-party libraries out there that implement the quick return listview UI pattern for iOS? The ones I could find were all for Android. Here are some:
https://github.com/LarsWerkman/QuickReturnListView
https://github.com/felipecsl/QuickReturn
This probably developed as an Android concept, but it isn't unusual for devs to be inspired by UI patterns and port them to another platform. I'm not an iOS dev. If there is already an easy built-in mechanism to do this, it's even better.
