Understanding the TTNavigation Demo

[elpuerco]

Hi

I'm creating a new app to learn how to use TTNavigator rather than the
stock UINavigationController.....but am not getting very far!

When I create a new project and add three20 all goes well, but then
when I try to add code to match the nav demo I just get a black
screen?

I see there is no nib use, in fact I see no assignment to a
window.......

cannot someone point me to where I am going wrong?

Thanks

Have you looked at the samples/TTNavigatorDemo project?

Yes, as per the title of my thread ;-)

I guess I read that as "I'm building a navigation demo app", not "I'm trying to understand the TTNavigator sample"...

Are you saying your app has the same code but behaves differently?  I guess you have to go diffing the project.pbxproj files.

Hi,

I created a new window based app and added the code as in the demo project, removed the references to window as they do not appear in the demo as well as removing the xibs.

The app compiles and runs with no error, just a black screen.

I have now found that the didFinishLauching does not get called???

I see no difference in my sections of code in relation to the demo?

I also read another post going back a while where someone had exact problem but solution was not posted.

I don't know where to look?

Have even tried adding a window with no joy?

Open "main.m" in "Other Sources" and find this line:

int retVal = UIApplicationMain(argc, argv, nil, nil);

You will need to change the last parameter to a string containing name of your app delegate. For example, my app delegate is declared as "@interface AppDelegate", so I would write:

int retVal = UIApplicationMain(argc, argv, nil, @"AppDelegate");

Cheers,

Ding Dong!  Thanks Jeff, now I can get to learning ;-))))

This needs to go into the FAQ. I'll add that in. It's a very common
Three20 beginning problem. Primarily, because very few people touch
the main.c and even the prefix files. It's been the cause of a lot of
confusion for people. These little issues will go away. :)
