    how should I remove a webView when call another ?

    if I run my small app with activity monitor (instruments)
    you can see each time you call a webView then the memory increases, and add 4 or 5 MB each time pressing the button (calling a local HTML)

    my question is:
    how can I remove a webView before call another webView please.

    here is the url of the small proyect to see see the problem.

    please help , and one more time thanks.

    I did not download your code - but are you creating a whole new webview each time? I would create a single webview, and just load new content into it. It'll probably be faster too.

    if (webView != nil)
    [webView release];
    webView = [[UIWebView alloc] initWithFrame:[myHTML_ojo1 bounds]];
    [myHTML_ojo1 addSubview:webView];	
    That's the code that makes a whole new webView - don't do this when you click the button. Do it once when the view is first shown.

    NSString *filePath = [[NSBundle mainBundle] pathForResource:@"head-mandiblev" ofType:@"html"];
    NSString *html = [NSString stringWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:nil];
    [webView loadHTMLString:html baseURL:[NSURL fileURLWithPath:[[NSBundle mainBundle] resourcePath] isDirectory:YES]];
    That's the code that loads the HTML into the view. That's the stuff that you want to do when the button is pushed.
