Question

Hi guys I’m trying to load an html page, and after the loading I want to be executed change.php?lang=eng.
I have this now when the program starts:

- (void)viewDidLoad {
    [super viewDidLoad];
    self.title = @"Treviturismo.it";
    link = @"http://www.treviturismo.it/dev/index.php";
    NSURL *url = [NSURL URLWithString:link];
    NSURLRequest *requestObj=[NSURLRequest requestWithURL:url];
    [myWebView loadRequest:requestObj];
}

Maybe I can do an IF to check if the page has been loaded, then:

link = @"http://www.treviturismo.it/dev/change.php?lang=en";
NSURL *url = [NSURL URLWithString:link];
requestObj=[NSURLRequest requestWithURL:url];
[myWebView loadRequest:requestObj];

Is this a good way?? I don’t know what to type in the if(), to check if the first page has been loaded!
Can anyone help me?
thanks!

You should listen for the page loading event using the UIWebViewDelegate protocol.

- (void)viewDidLoad
{
   [super viewDidLoad];
   // init code...

   myWebView.delegate = self; // your class must implement the UIWebViewDelegate protocol

   link = @"http://www.treviturismo.it/dev/index.php";
   NSURL *url = [NSURL URLWithString:link];
   NSURLRequest *requestObj=[NSURLRequest requestWithURL:url];
   [myWebView loadRequest:requestObj];
}

- (void)webViewDidFinishLoad:(UIWebView *)webView
{
   // if you want this method to not being called again, do this :
   webView.delegate = nil;

   // then do your request to change.php here
   link = @"http://www.treviturismo.it/dev/change.php?lang=en";
   NSURL *url = [NSURL URLWithString:link];
   requestObj=[NSURLRequest requestWithURL:url];
   [webView loadRequest:requestObj];
}
