Typos on my part
It's applicationDidFinishLaunching:
That delegate method is in the file App_Delegate.m, which is the
App_Delegate file.
The App_Delegate file is a delegate of the app.
Basically, I have some code working with outlets.
If I put it as a method in App_Delegate, it works. I call it like
this from applicationDidFinishLaunching:
[self doStuff];
If I move the doStuff method to the FirstLaunch.m file and call that
method, again, from applicationDidFinishLaunching, it doesn't work:
FirstLaunch *thing = [[FirstLaunch alloc] init];
[thing doStuff];
So in App_Delegate's applicationDidFInishLaunching method, I have
something that looks like this:
[self doStuff];
FirstLaunch *thing = [[FirstLaunch alloc] init];
[thing doStuff];
And either the first line is commented out or the last two are
commented out. The method they are calling is the same, just located
in different files. Both App_Delegate and FirstLaunch have the Outlet
ivars connected in IB and give no warnings or errors.
Thanks for your help,

Hi,
are you using - (void)applicationDidFinishLaunch:(NSNotification
*)aNotification or - (void)applicationDidFinishLaunching:
(NSNotification *)aNotification ? The first is not a valid delegate
method, the second is. Have you connected your AppDelegate as
delegate of your app - can it receive the notification at all?
And can you clarify on the difference of an App_Delegate file vs.
App_Delegate.m ?
Cheers,
Volker

I have a App_Delegate file. In applicationDidFinishLaunch:, I
instantiate a FirstLaunch object and call its start method. The
weird thing is that this method, which access several IBOutlets,
seems to be working with null outlets. All the connections are
right in IB, and yet the outlets are null. I put the method inside
App_Delegate.m and set the same connections, and the outlets work
fine. I've been staring at the files for an hour, trying to figure
out where I went wrong. The connections are the same, the headers
have the same ivars, and yet in one file, the outlets work fin, and
in another they're null.
Thanks,
