i've tryed to implement a UIScrollView in pure auto layout mode, using the ios tech note and a very well explained blog (which was using objective c).
apple technote: https://developer.apple.com/library/ios/technotes/tn2154/_index.html
Whatever i do, this constraint is always added and breaks autolayout by forcing the ContentSize instead of letting the ContentSize be driven by the autolayout.
"<_UIScrollViewAutomaticContentSizeConstraint:0x14269d00 Ac.Touch.Views.ConnectionsScrollView:0x140adb70.contentWidth == 0.000000>"
I now think it is a bug in monotouch.
See my post on stackoverflow: http://stackoverflow.com/questions/20784653/uiscrollview-with-autolayout-pure-approach
I used the same appearance hierarchy and constraints, but i keep having the error 'Unable to simultaneously satisfy constraints'. The problem relies in the 'Container View' whose constraints can not be set to 0 right/bottom spaces of the scrollview without triggering the error. But if these constraints are removed, the 'Container View' has no width/height and the scrollview does't scroll.
I've created a new scrollview in pure autolayout mode and it works ok.
So i'll check again back into my 2 others examples to see what is really wrong.
