Note: My VCs are using Autoconstraints. I'm not sure why some buttons on my VCs are not responding after I rotate from landscape to portrait and vice versa.
I got a hunch that this has something to do with Autoconstraints, but got no idea how to prove it.
Not using any animations either.
Yes I assign IBActions properly and they all respond well if I lock on a single orientation, problem occurs when I start rotating my app.
