Okay, I've verified that the page has loaded correctly (by running [webView stringByEvaluatingJavaScriptFromString:@"document.body.innerHTML"] to output the HTML of the loaded webview and then comparing it with the page loaded by the Mac version to ensure that they're the same.)
I've come to the conclusion that the problem is that the Javascript is taking longer than 10 seconds to complete. This is a bit of a problem since the Javascript is sending user credentials to the server and the server takes a little over 10 seconds to service that request and send back (a rather large) packet of data - which then needs to be processed. On the Mac, this takes a little under 10 seconds - on the iPhone it wouldn't surprise me if it took rather longer. So my question is this - how can I override this 10 second limit, if only to test my theory (i.e. even if that isn't permitted in a shipping app, can I do it for debug purposes)? Does anyone have any ideas for circumventing this problem (rewriting the HTML of the page is not, sadly, an option). Or is it a case that there are some things that simply can't be done on iOS?
