For the past month I have been working on a personal iOS component after seeing and being inspired by a custom UI transition in an iPad app that I downloaded recently.
Since then I have been trying to reverse engineer it with some tweaks here and there. The goal was to be able to license it out for others to use, but the more that I thought about it I just can't justify charging for it. It it turns out the way that I want to I feel, and hope, that more devs can benefit from it by including it in their apps so I will open source it on github.
I have some more work to do before I post even an "alpha" preview, but I am hoping within in the next few weeks it will be ready for people to comment on and possibly improve.
