Question

I downloaded the Red Laser MonoTouch sample and ran the project in MonoDevelop, I had to first update the solution file so that it would load up in MonoDevelop.

When I try to view one of the .xib files in the Xcode Interface builder I get the error:

Error updating Xcode project. Could not generate outlet
‘overlayController’ in class ‘RedLaserSample.RLSampleViewController’
as its type ‘RedLaserSample.OverlayController’ could not be resolved
to Obj-C.

Details:

Answer 1

You need to add [Register (“OverlayController”)] to your OverlayController class.
