I have recorded a video to explain, this is really easy to reproduce.
I have also managed to reproduce this by swiping up in the gesture recogniser (but not as often).
I had the very same problem.
The issue was always happening when panning down to dismiss the keyboard. I can't reproduce the issue anymore since I updated the code to the latest available (I had an old version of DAKeyboardControl ; see #35).
I suggest we close down this issue, as it seems a duplicate of issue #17 - "Keyboard isn't re-anabled correclty" (now fixed).
I will check out and see if I can reproduce this issue with the latest version of DAKeyboardControl, thanks @gcerquant
I think this can still happen. Perhaps it has to do with using DAKeyboardControl on two views? I'm using it in the pageviewcontroller on the different view controllers. I remove it on a page when it disappears, but at times you can see two pages while swiping, so two versions would be alive.
