Have you used Tinder app? That app is full of nice effects that makes a great UX experience in my opinion.
Try to open it and you see the launch image with a red flame at the center of the screen.
Seconds after the flame moves itself to the navigation bar to make the app logo.
The animation I am trying to create it exactly that and I can't figured out how to (1) let the navigation bar appear in that way and (2) to transition a custom UIView
inside another view.
If I'd find an app to record the screen of my iPhone I will post a video explaining the animation I'm referring to.
In the meanwhile, do you have any ideas?
