I am implementing walking tour for the first time user in the application. I do not know is there a better way of doing it, but I have implemented the following approach which detects user taps via tap gesture recognition.
I wonder how could I handle if I have more than one image? Or is there any better or recommended approach for the walking tour?
It is totally up to you how you want yo implement this. The approach you have mentioned have nothing wrong.
For your question if you have more than one images then you can create a container view on which you can add multiple imageViews. And On Touch on that container you can show hide image view based on your sequence.
