insertSubView:atIndex: is not a valid UIView method. You have subtle error in that line of code. Recheck the documentation; the error should stick right out.

Thanks. I re-entered the line and it worked. However when I ran it I get a message saying that the view outlet was not set. I have checked and there is a connection from the File's Owner to the view - so I am a bit confused.

Can somebody help ? thanks

regards

Without your Xcode project, it's rather difficult to help you find out why your connections aren't working.
