Set new url of NSURLRequest and call [webView loadRequest:requestObj]; after any time interval you want again.

NSTimer will help you to call method after some interval.

// after loading first url:
NSTimer *timer = [NSTimer scheduledTimerWithTimeInterval:60 target:self selector:@selector(loadNewUrl:) userInfo:nil repeats:NO];

//somewhere in delegate define selector
- (IBAction)loadNewUrl:(NSTimer *)timer
{
     NSURL *url = [NSURL URLWithString:@"http://www.apple.com/stevejobs"];

     //URL Requst Object
     NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];

     //Load the request in the UIWebView.
     [webView loadRequest:requestObj];
}

UPDATED:
Implement in your “ methods to detect when webview finished loading first url:

- (void)webViewDidFinishLoad:(UIWebView *)webView;
- (void)webView:(UIWebView *)webView didFailLoadWithError:(NSError *)error;
