基本上我是參考這一篇文章，重點的地方在影片部份，可惜影片被移除，試了兩天才試出關鍵點。

@interface StockNews_iphone : UIViewController <UIWebViewDelegate> {
IBOutlet UIWebView *stockNews;
IBOutlet UIActivityIndicatorView *activityIndicator;
}

- (void)viewDidLoad
{
[super viewDidLoad];
[stockNews loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"http://網址"]]];
}
- (void)webViewDidStartLoad:(UIWebView *)webView
{
[activityIndicator startAnimating];
}
- (void)webViewDidFinishLoad:(UIWebView *)webView
{
[activityIndicator stopAnimating];
}

除了拉Activity Indicator View 和 Web View 外，在Files Owner裡將Web View拉入delegate！ (之前沒拉，ActivityIndicator都不會轉，弄半天才知道是這裡少做一個步驟。)
