I'm having this issue as well. I made a project straight out of Xcode4 with two view controllers. I added some textfields and a button, hooked up the outlets to the textfields and an action to the button, everything was fine. I then came back later, added some code for push notifications, tried to build, and got this "coding-compliant" error about one of my textfields. If I removed the textfield and all outlets etc, it would then complain about the next one. I removed all controls, and it then was erroring about the view itself. I've tried deleting the view in Xcode, remaking it, recreating the outlet the file's owner, and the only way to get it to go away is to delete the view and everything referring to it.
I read on the MonoTouch site that this error is due to something not being generated correctly in the designer.xib.cs generated file: http://support.xamarin.com/customer/portal/articles/135125-this-class-is-not-key-value-coding-compliant-for-the-key-xxxx But those files don't exist in Monodevelop. Someone said you can manually create them, but will that actually fix this? Is there an easier way to get MT to regenerate these files and fix the problem if that's really the issue?
