Question

With [NSURLConnection sendSynchronousRequest] method I get, with a GET request, a list of records from html page.

The records are paged at intervals of 20. To get the pages following the first, a function is called

javascript: GoToPagina (n)

where n is the number of page.

How can I call the function programmatically?

Answer 1

You need a UIWebView to do what you are asking about, as that is the only thing that can execute javascript on iOS. You can load it up with the URL in question, and when it’s done loading:

[myWebView stringByEvaluatingJavascriptFromString:
  [NSString stringWithFormat:@"GoToPagina(%d), pageNum]];

However, in order to do it with NSURLConnection directly, you can’t use JS. Instead, forgure out what URL the GoToPagina(n) function gets its data from and call that directly with another NSURLConnection.

If all you want is the data and you don’t want to show any webview at all, then this is more likely what you want to do.
