    [web release];
}

If this is the exact code you're using then it can't work: the webView added to topView that is never put on screen anywhere.

You probably want to add the webView to the controller view, but a better place to do that might be viewDidLoad, where self.view can be used safely.

This code works for me:

- (void)viewDidLoad {
    [super viewDidLoad];
    self.webView = [[[UIWebView alloc]
        initWithFrame:CGRectMake(0, 0, 320, 480)] autorelease];

    NSString *urlAddress = @"http://www.google.com";
    NSURL *url = [[[NSURL alloc] initWithString:urlAddress] autorelease];
    NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];

    [self.webView loadRequest:requestObj];

    [self.view addSubview:self.webView];
}
