iPhone – UIWebView loading but not displayed (Xcode 4, iOS SDK 4.3)

if(!webView)
{
 webView = [[ UIWebView alloc]init];
}

webView.delegate = self; 

I plan to write an application that includes UIWebView. So first I want to try it out by simply loading the URL.

>Create UIWebView in Interface Builder
>Connect to the code

@property (non-atomic, reserved) IBOutlet UIWebView * webView;

in viewDidLoad:

- (void)viewDidLoad { 
[super viewDidLoad];
if(!webView)
{
 webView = [[UIWebView alloc]init];
}

 webView.delegate = self;

[webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"http://www.google.com"]]]]; }

I also implemented didFailLoadWithError and webViewDidFinishLoad delegate methods.
Call webViewDidFinishLoad and indicate that HTML has been loaded.

The problem is: Even if webViewDidFinishLoad is called, UIWebView will not display the website. It only displays white. Touch and When dragging the UIWebView but not displaying the content, the scroll bars on the right and bottom are displayed. Nothing is found. It looks strange..

Edit
This screenshot shows the connection of the xib:

If you have correctly connected everything in Interface Builder, the following line is not required:

if(!webView)
{
 webView = [[UIWebView alloc]init];
}

webView .delegate = self;

Try to delete them and see what happens. Also, put an NSLog(…) in webView:didFailLoadWithError:callback and see if it is output.
