How to rewind the last napkin like Tinder

Question

I am working on an iOS app (using Objective-C).

I use the MDCSwipeToChoose API to flip through a view (like and dislike).

I want to add another button to the application (rewind the last hit, like a tinder ).

Answer 1

It looks like you want NSUndoManager. See the links below.

Answer 2

You can create a separate manager that will process the current card number. With the repeated action of the button, you can delete the previous map and animate the appearance of the new one. You can see how we implement this manager here: https://github.com/Yalantis/Koloda

Answer 3

You may need CoverFlow, this is a swipe animation, like a tinder, using a collection.
