Overriding loadView and setting rootViewController programmatically, no Storyboard - ios

Question

I'm trying to create and set a View as the root View programmatically. I'm not using a Storyboard or ARC.
I'm trying to set a UIWebView as my ViewController's root View, which I'm unable to do. When I run the following code, I see a NavigationBar with a blank white screen. I tried setting a regular UIView as the root View and set its background color to blue, which loaded, so the problem seems to be specific to a UIWebView.
I'd really appreciate it if someone could point out what I'm doing wrong. Thanks!
Here is my loadView code:
// in GmailOAuthViewController.m
- (void)loadView {
CGRect frame = [[UIScreen mainScreen] bounds];
UIWebView *webView = [[[UIWebView alloc] initWithFrame:frame] autorelease];
self.view = webView;
}
And here is my application:didFinishLaunchingWithOptions: code:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
CGRect frame = [[UIScreen mainScreen] bounds];
UIViewController *viewController = [[GmailOAuthViewController alloc] init];
self.navigationController = [[UINavigationController alloc] initWithRootViewController:viewController];
self.window = [[UIWindow alloc] initWithFrame:frame];
self.window.backgroundColor = [UIColor whiteColor];
self.window.rootViewController = self.navigationController;
[self.window makeKeyAndVisible];
return YES;
}

Answer 1

you are assigning self.view...
if you assign webView to view everything else is gone
try
[self.view addSubview: webView]
this is code i just tried and it works
CGRect frame = [[UIScreen mainScreen] bounds];
UIViewController *viewController = [[ViewController alloc] init];
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:viewController];
self.window = [[UIWindow alloc] initWithFrame:frame];
self.window.backgroundColor = [UIColor whiteColor];
self.window.rootViewController = navigationController;
[self.window makeKeyAndVisible];
in ViewController.m
-(void)viewDidAppear:(BOOL)animated{
CGRect frame = self.view.bounds;
UIWebView *webView = [[UIWebView alloc] initWithFrame:frame] ;
webView.delegate = self;
self.view = webView;
NSString *thePath = [[NSBundle mainBundle] pathForResource:#"ViewControllerCatalog" ofType:#"pdf"];
if (thePath) {
NSData *pdfData = [NSData dataWithContentsOfFile:thePath];
[(UIWebView *)self.view loadData:pdfData MIMEType:#"application/pdf"
textEncodingName:#"utf-8" baseURL:nil];
}
}
I apologize I told you wrong earlier you do in fact assign to view
