Progress on new sites (like airbnb tablet site)

[raver99]

Hello,

I think your control is great and would love to use it but some new sites (airbnb on iPad iOS 8.0) gets stuck at 50%.

Could you please have a look, or maybe point out what goes wrong.
Thanks,
R.

I checked this issues running on iOS 7.1 (built with 7.1 SDK).
Here it works fine so I guess something changed in 8.

I will try to figure it out myself, might take a while, but I would enormously appreciate your help.
Thanks,
Roland

Did you happen to find a good fix? I am about to go home, but I've stumbled over the same problem. I think the problem is here:

- (void)webViewDidFinishLoad:(UIWebView *)webView
{
    if ([_webViewProxyDelegate respondsToSelector:@selector(webViewDidFinishLoad:)]) {
        [_webViewProxyDelegate webViewDidFinishLoad:webView];
    }

   _loadingCount--;
    [self incrementProgress];

   NSString *readyState = [webView stringByEvaluatingJavaScriptFromString:@"document.readyState"];

    BOOL interactive = [readyState isEqualToString:@"interactive"];
    if (interactive) {
        _interactive = YES;
         NSString *waitForCompleteJS = [NSString stringWithFormat:@"window.addEventListener('load',function() { var iframe = document.createElement('iframe'); iframe.style.display = 'none'; iframe.src = '%@://%@%@'; document.body.appendChild(iframe);  }, false);", webView.request.mainDocumentURL.scheme, webView.request.mainDocumentURL.host, completeRPCURLPath];
        [webView stringByEvaluatingJavaScriptFromString:waitForCompleteJS];
    }

    BOOL isNotRedirect = _currentURL && [_currentURL isEqual:webView.request.mainDocumentURL];
    BOOL complete = [readyState isEqualToString:@"complete"];
    if (complete && isNotRedirect) {
         [self completeProgress];
    }
}

specifically this line:

BOOL isNotRedirect = _currentURL && [_currentURL isEqual:webView.request.mainDocumentURL];

I've noticed that in my case, the URL is changed (probably by Javascript), after the hash sign. Thus isNotRedirect was false.

I'm going home now and I don't know if this is a clean fix or even a fix, but it appears to work now for me using this code:

BOOL isNotRedirect = YES;

if (_currentURL != nil && _currentURL.fragment != nil) {
    NSString *nonFragmentCurrentURL = [_currentURL.absoluteString stringByReplacingOccurrencesOfString:[@"#" stringByAppendingString:_currentURL.fragment] withString:@""];

    NSString *nonFragmentMainDocumentURL = [webView.request.mainDocumentURL.absoluteString stringByReplacingOccurrencesOfString:[@"#" stringByAppendingString:webView.request.mainDocumentURL.fragment] withString:@""];

    isNotRedirect = _currentURL && [nonFragmentCurrentURL isEqual:nonFragmentMainDocumentURL];
}

To detect the redirect I use the URLs without the fragment.
