Question

I have got a sample app where i have delegate method and a main controller and mainwindow.xib.
when i application is loaded it directly loading.But i want to do some changes like adding buttons and other UI things.But i dont have a nib file.So i added new nib file name called Newview.xib.

So my requirement is how to load this nib file on launch, what all changes i have to make in appdelegate method.Present code which is running is below

(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {  

    mainController = [[MainController alloc] init];

    [window addSubview:mainController.view];
    [window makeKeyAndVisible];

    return YES;

}

Answer 1

In your sample application, the app gets the .xib-file by searching for one with the same name as its view controller. In your new situation, where you would like to define yourself which .xib-file to use, you can implement:

initWithNibName:bundle:

and specify the name of your .xib as the first argument (without “.xib” attached to it).
