Question

I have an app that works with tabs and webview. I already have it setup to refresh the page assigned to a tab each time the item on tabbar is selected. My problem now is that it takes some time to load the page and it’s impossible to say if the page being displayed is the old or refreshed one.

What I want to do is add a “loading” screen (a simple image) which will be displayed until the refreshed page is loaded. Here is the function I run on each tab tap:

- (void) goToPage:(NSString *)sid
{
    NSString *newURL = [NSString stringWithFormat:@"%@/mykingdom.php?sid=%@", appURL, sid];

    [secondView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:newURL]]];
}

Thanks!

UIWebViewDelegate has 2 handy methods:

– webViewDidStartLoad:(UIWebView *)webView
– webViewDidFinishLoad:(UIWebView *)webView

you can easy implement and do whatever you like.
