nevermind. i didnt name my navigationcontroller “navigationcontroller”. i made a short name “navcontr” which did not work at all. appr u cant just name them whatever…
and also. remeber to put everything in a view in the rootviewcontroller.xib and not in a window. this will cause it to not display anything. learned from my mistakes.

it keeps telling me that “self.navigationcontroller” in “rootviewcontroller.m” :

“request for member ‘navigationController’ in something not a structure or union”

why?

You almost had a great tut until you dropped

“Also make sure you make a new reference outlet for your Navigation Controller to your App Delegate.”

What? Is that Greek? I have NO idea what that means and once again stopped following the tutorial and gave up on iPhone programming for a while. ARGH.

Almost.

Thanks for the tutorial. I’m just learning the language (brand new to C of any kind!) and your example introduced some simplicity to the picture and brought things into perspective for me. I appreciate your having taken the time.

Tried to follow this using Xcode 4.0.1. It’s way too different to be able to follow step by step like the rookie I still am.

Just to clarify — to get this to work I used the advice of two comments:

1. Alan Zeino:

For those of you unsure of what he meant by some things, “Also make sure you make a new reference outlet for your Navigation Controller to your App Delegate” means control-clicking on the Navigation Controller in MainWindow.xib and linking to ‘Nav App App Delegate’ (or whatever you’ve called your app + App Delegate), and “once here we will make a few connections” means opening the xib for your second view (called View2.xib in the example), selecting ‘File’s Owner’ in the xib window, changing its type/class to ‘UIViewController’ in the Controller Identity Inspector (command + 4) under ‘Class Identity’, and then making a reference to ‘view’ in the Connections Inspector (command + 2) for ‘File’s Owner’.

2. Himanshu

Open Navigation App Delegate Inspector Panel (Third Item in MainWindow.xib). Click on + sign in front of navigationController outlet and drag it to Navigation Controller in MainWindow.xib.

Thanks for a great tutorial, the code really came in handy, helped me to see how the delegates knitted together.

I used it in XCode4, with little changes needed.

For those only seeing a white box. Try this.

Select the App Delegate in MainWindow.xib. Then in connections inspector clickand hold in the circle next to navigationController and drag to NavigationController in the MainWIndow.xib.

I think you left something out, or something changed in the new version. Only the window in MainWindow.xib is being loaded, not the Navigation Controller that we added.

Hey… Its a nice code….
but how can add this to a tabbar application?

Does not work for me :-(. No black view with button. I see only the empty white window. I.e. loading from loading from RootViewController.nib does not happen.
