UIWebview缓慢加载安全页面

Question

I have a site I'm loading with a UIWebView that has some problems loading when secured with Basic Authtype of Apache:

NSString * myUrlAddress = [NSString stringWithFormat:@"http://user:pass@mysite.mydomain.com"];
NSURL *url = [NSURL URLWithString:myUrlAddress];
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url cachePolicy:NSURLRequestReturnCacheDataElseLoad timeoutInterval:60.0];
[webView loadRequest:requestObj];

Initial loading works most of the times, but sometimes, especially on reloading of the app the callback

- (void)webViewDidFinishLoad:(UIWebView *)webViewloc

is not reached, and it is also not running into

-(void)webView:(UIWebView *)wv didFailLoadWithError:(NSError *)error

If I use a different server without .htaccess to secure the page it all works fine.

I also see in the access log, that it sometimes just stops loading from the page.

Has this something to do with cachePolicy or timeoutInterval ?

Answer 1

You could try to manage the authentication challenge coming from the server on your own, since it seems that UIWebView is not able to handle it.

This requires setting up your own NSURLRequest/Connection and handle the challenge in the connection:didReceiveAuthenticationChallenge delegate method before trying to load the actual html page in your UIWebView .

You can find full sample code here for a GET request. You might also check into a third-party networking framework that makes handling the communication and the challenge easier (eg, ASIHTTPRequest , although it is now in a "frozen" state it works well; or AFNetworking )

Answer 2

NSString * myUrlAddress = [NSString stringWithFormat:@"http://user:pass@mysite.mydomain.com"];
NSURL *url = [NSURL URLWithString:myUrlAddress];
[webView loadRequest:[NSURLRequest requestWithURL:url]];
