Work around to Xcode 4 NIB Name drop-down not populating

[RomanRobot]

I'm pretty sure the few of you using Xcode 4 have encountered the same problem. I want to know what work around people have been using, since this is a huge problem.

For those of you who don't know what I'm talking about:
Let's say for example I am to create a UINavigationController in the NIB. Now I expand it to show the Root View Controller of the UINavigationController. I click the Root View Controller so I can point it to an existing NIB file I've already made in the Attributes Inspector. When I click the NIB Name drop-down list, nothing. It's empty. I've tried cleaning the targets and a whole bunch of other stuff, but how would I set the Root View Controller of the Navigation Controller programmatically?

So I answered my own question once again. :P

I just had to import the class at the top of the App Delegate's implementation file

#import "RootViewController.h"

in the application:didFinishLaunchingWithOptions: I just had to create the RootViewController object and init the navigation controller with it.

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    // Override point for customization after application launch.
    RootViewController *navigationRootViewController = [[RootViewController alloc] init];
    [navigationController initWithRootViewController:navigationRootViewController];
    
    self.window.rootViewController = self.navigationController;
    [self.window makeKeyAndVisible];
    return YES;
}

There's only one anomaly with my solution. When I run it, it shows the RootViewController as a detail view and the back button says Root View Controller

which when pressed goes to the... RootViewController. The same thing.

Any ideas how I could make it not start in a detail view with the same thing?

[navigationController initWithRootViewController...

You can't (or at least, shouldn't) take an existing object and init it again. The only thing that should be immediately to the left of an init* method is [WhateverClass alloc].

So it would seem that what you've accomplished is to push another view controller on the stack. Since you did a bad thing to start with, I'd say that this is probably falling into the realm of "the behavior when you do this is undefined."

I'm not entirely sure that I understand the complaint, but I can't honestly say that I've ever seen the NIB Name menu contain anything useful. Or at all. But it isn't really necessary anyway. If you go to the Identity inspector (3rd from left in Xcode 4), there you can specify your custom class. Just define this, and then you can leave the NIB Name selection blank. The only 3-vs-4 difference I've seen with the Class menu is that 4 seems to be case-sensitive, where 3 was not.

For some reason it doesn't work on a sample project with a table view controller instead of a view controller that I made for a tutorial. I tried it in my main project though and it worked. Ah well, spot on! Thanks again! ^.^
