Question

I’m trying to present a standard ViewController modally, but can’t figure out how to do it. The view controller will have buttons which will ultimately trigger the dismissing actions, so I don’t need to wrap it in a NavigationController. Also, I’m doing all of this programmatically, without .xibs.

Here’s the code I’m using:

- (void)viewDidAppear:(BOOL)animated {
    NSLog(@"view did appear within rootviewcontroller");
    WelcomeViewController *welcome = [[WelcomeViewController alloc] init];
    [self presentModalViewController:welcome animated:true];
    [welcome release];
}

The problem is that I haven’t set the WelcomeViewController's view, so loadView is not getting run, which means no content is being drawn to the screen.

Every example I find, including Apple’s, uses either a .xib to initialize the ViewController, a NavigationController that adds a RootViewController, or both. My understanding is that loadView is called automatically for you in both of these scenarios.

Where do I configure my WelcomeViewController's view? Right there after the alloc/init? Inside WelcomeViewController's init method?

Thanks!

Override the loadView method in your subclass. See View Controller Programming Guide for iOS.
