When I attempt to carry out step 12 on page 94 I feel like when I right click and drag over that the Hello World View Controller and the Window base are not associating.

How do I know that they are associating correctly?

Also:

When I hit Command-R it succeeds BUT I just get a plain white screen and the debugger gives me 3 warnings that read

Under CompileXIB Classes/HelloWorldViewController.xib: (I get this warning)

The 'view' outlet of the 'File's Owner is connected to 'View' but 'view' is no linger defined on HelloWorldView Controller

Under the Compile windowbasedAppAppDelegate.m: (I get these 2 warnings)

1. Property 'viewController' requires method '-viewController' to be defined -use @synthesize, @dynamic or provide a method of implementation

2. Property 'viewController' requires the method 'setViewController:' to be defined - use @ synthesize, @ dynamic or provide a method of implementation

Can someone please give me some guidance so that I understand what I did wrong and what I need to do to correct this problem please.

First I would make sure on page 93 that you entered everything that is needed. There are no bold lines of code and the following should be bold and must be input into the project:
If this doesn't resolve your problem. I would suggest that you redo the project, in case you made some errors following the steps. If the redo works, try to locate the discrepancies between the 2 projects.
If that doesn't help you could send me your project files at
[email protected]
and I will diagnose it.

Hello

Page 94 step 12 isn't very clear. Don't see how to wire the delgate and view controler by dragging.

Thanks for any help

When you drag from the WindowBasedAppDelegate item to the HelloWorldView Controller a delegate outlet option should be available. Click on the word "delegate" in the drop-down menu that appears. Alternatively, you can right-click or control-click the WindowBasedAppDelegate item opening the Outlets/Actions info window and drag from the empty circle to the right of the delegate outlet option to the HelloWorldView Controller. You will know that the connection has been made because the name of the outlet will appear next to the word "delegate" in the WindowBasedAppDelegate item and the circle will now be filled with a dot.
If the delegate option is not appearing, refer to the previous bold code posting to ensure that you have entered all necessary code. Also, make sure you have saved your work in Xcode. Outlets typed in Xcode only appear in Interface Builder after they have been saved.
Let me know if this helps.

Some times even with years of programming experience, I can be a little slow. When they say control click they mean hold down the control key and then click. When I did this I was able to link the delegate and the view.
