iOS: WebView Loading a url

Question

I am trying to open the following url in UIWebView but it fails to load whereas changing it to:

 http://www.google.com

works fine

Answer 1

I would try encoding all of the key/value items in your url. Specifically the curly braces ({}) and the hash (#) symbols may be causing a problem.

Answer 2

Your line of code looks convoluted, but basically it is a very simple one.

You should breakup this code from a one liner to multiple lines that are more readable. That will also allow you to log and check the URL you actually created, like so:

NSLog(@"My url: %@", urlString);

Update: I see you added the full url. Webview indeed fails to load that url (UIWebkit error 101).

The part of the url that causes the problem is the '#' character and dictionary that follows in the params. You should url encode that part of the url.

Try this:

NSString *address = @"http://m.forrent.com/search.php?";
NSString *params1 = @"address=92115&beds=&baths=&price_to=0";

// URL encode the problematic part of the url.
NSString *params2 = @"#{%22lat%22:%220%22,%22lon%22:%220%22,%22distance%22:%2225%22,%22seed%22:%221622727896%22,%22is_sort_default%22:%221%22,%22sort_by%22:%22%22,%22page%22:%221%22,%22startIndex%22:%220%22,%22address%22:%2292115%22,%22beds%22:%22%22,%22baths%22:%22%22,%22price_to%22:%220%22}";
params2 = [self escape:params2];

// Build the url and loadRequest
NSString *urlString = [NSString stringWithFormat:@"%@%@%@",address,params1,params2];
[self.webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:urlString]]];

The escaping method I used:

- (NSString *)escape:(NSString *)text
{
    return (__bridge NSString *)CFURLCreateStringByAddingPercentEscapes(NULL,
                                                                        (__bridge CFStringRef)text, NULL,
                                                                        (CFStringRef)@"!*'();:@&=+$,/?%#[]",
                                                                        kCFStringEncodingUTF8);
}
