In the pod's Example project go to MXScrollViewController tab
Scroll down so that some part of view is not shown anymore (is out of screen)
Go to some other tab
Return to MXScrollViewController tab
See the empty space at the bottom of the view (just above the tab bar)
I discovered that the empty space means that the frame of ScrollView changed (the height reduced). The height of empty space is the same as tab bar's height.
If you leave this screen without previously scrolling down and the whole view is shown then the issue is not reproduced.
Maybe, this info will help.
