I have a main window which has the UITabViewController as its root controller. I am using a nib file for this. In Interface Builder, two of the tabs have been wired to Controller_A, Nib_A and Controller_B, Nib_B but the 3rd tab only knows about Controller_C.

I assumed that this would mean that the loadView method of Controller_C would be automatically called since I haven’t bothered to specify the NIB file. I want to lay this piece out programmatically. And it DOES indeed get called as I’ve confirmed by placing a breakpoint inside this method.

BUT when I switched over to Controller_C in the simulator, it comes up empty!

Here’s what the loadView of Controller_C looks like:

- (void)loadView
{
    [super loadView];
    ...
    [self setTableView:formTableView];
    [view addSubview:formTableView];
    [self setView:view];
}

Any tips? What am I ignoring?

    It seems loadView works as expected, the reason that my view was blank is because the datasource for my tableview was actually NIL. Earlier, I did not consider this scenario as I thought that it would at least present an empty table in such a case but apparently that was an incorrect assumption on my part. All this mistakenly led me to believe that the view wasn’t being initialized properly.

    @cduhn: Thanks, I had been following steps 1-3 already and it was really good to hear someone else give the same advice. The rest of what you said was educational for me as well.

    Thanks Everyone.
