uiwebview not loading the web page - iphone

Question

in my program uiwebview is not loading the url address.when i nslogged the request object is not null.however when i nslog the webview.request it returns null.what may be the reason it is not loading
- (void)viewDidLoad {
[super viewDidLoad];
self.web = [[UIWebView alloc] init];
NSString *urlAddress = #"http://www.google.com";
NSURL *url = [NSURL URLWithString:urlAddress];
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
NSLog(#"%#",requestObj);
[self.web loadRequest:requestObj];
[web setFrame:CGRectMake(0, 0, 320, 370)];
NSLog(#"%# %#",self.web,self.web.request);
}
the nslog results are
<NSURLRequest http://www.google.com>
<UIWebView: 0xbb17ff0; frame = (0 0; 320 370); layer = <CALayer: 0xbb12f20>> (null)
as per suggestions from this site i changed it from IB and made it to code .i made the class confirm to uiwebview delegate..both the webviewdidstart and webview did finish are being called these are the nslog outputs from these methods
webviewdidstart
webView-----><NSMutableURLRequest >
webView-----><NSMutableURLRequest http://www.google.com>
webview did finish
webView-finished----><NSMutableURLRequest http://www.google.com>
webView-finished----><NSMutableURLRequest http://www.google.com>
still nothing is being called and i think both these methods are called twice

Answer 1

This is a working code, test this out in your application and let us know the outcome
in .h file, add UIWebViewDelegate
in .m file's viewDidLoad, add this:
UIWebView *webview=[[UIWebView alloc] initWithFrame:CGRectMake(0.0,0.0,320.0,460.0)];
NSURL *url = [NSURL URLWithString:#"http://www.google.com"];
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
webview.delegate = self;
[webview loadRequest:requestObj];
[self.view addSubview:webview];
Now check in the delegates if your page is loading or not:
- (void)webViewDidStartLoad:(UIWebView *)webView {
NSLog(#"page is loading");
}
-(void)webViewDidFinishLoad:(UIWebView *)webView {
NSLog(#"finished loading");
}

try like this
CGRect webFrame = CGRectMake(0.0, 0.0, 320.0, 460.0);
UIWebView *webView = [[UIWebView alloc] initWithFrame:webFrame];
NSString *urlAddress = #"http://www.google.com";
NSURL *url = [NSURL URLWithString:urlAddress];
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
[webView loadRequest:requestObj];
[self addSubview:webView];
[webView release];
