body: <p>i have a tab bar control. 1st tab contains a navigation control. On the 2nd tab i want to load a web page (say google.com). I have written the code as </p>
  
  <p><strong>NPIViewController.h</strong></p>
  
  <pre><code>@interface NPIViewController : UIViewController {
     IBOutlet UIWebView *webView;
  }
  @property (nonatomic,retain) IBOutlet UIWebView *webView;
  @end
  </code></pre>
  
  <p><strong>NPIViewController.m</strong> </p>
  
  <pre><code>- (void)viewDidLoad {
    [super viewDidLoad];
    NSURL *url = [NSURL URLWithString:@"http://www.google.com"]; 
    NSURLRequest *request = [NSURLRequest requestWithURL:url]; 
    [webView setScalesPageToFit:YES];         
    [self.webView loadRequest:request];               
  }
