UIWebView Loading content properly on iOS 6 simulator but not on device?

Question

I have encountered a weird bug with a released app. My UIWebView is no longer loading content on iOS 6, yet the content still displays in the simulator. The activity indicator displays properly but then it loads a blank url? Again, this only happens on a device, not on the simulator.

To provide extra context (in the simulator the NSURLRequest is assigned the proper URL. When run on a device the value is nil.)

Here is my code :

-(void)loading
{
    if(!self.webView.loading)
        [self.activityIndicator stopAnimating];
    else {
        [self.activityIndicator startAnimating];
    }
}


- (void)viewDidLoad
{
    [self.webView addSubview:self.activityIndicator];
    NSURLRequest *requestUrl = [NSURLRequest requestWithURL:self.url];
    [self.webView loadRequest:requestUrl];
    self.timer = [NSTimer scheduledTimerWithTimeInterval:(1.0/2.0) target:self selector:@selector(loading) userInfo:nil repeats:YES];
     [super viewDidLoad];
    NSLog(@"%@", requestUrl);
}

I had a similar issue with our web app (HTML+JS+CSS) not loading on a device, but working fine in a browser and iPhone Simulator. The cause of the issue was the wrong case in filenames. E.g., HTML file wanted to load a file 'Loader.js', whereas its name was 'loader.js'.

So, maybe you should check your 'self.url' (if your 'index.html' has the right case in its filename).
