今天用UIWebView加载https时出现此服务器的证书无效，然后在网上找解决方法，发现并不是很完美，根据自己的理解修改如下：

1.在webview出现的XX.h文件中加入NSURLConnectionDelegate代理，并声明以下变量

NSURLConnection *_urlConnection;

NSURLRequest *_request;

BOOL _authenticated;

2.在xx.m文件中加入以下方法

- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType;{    if (!_authenticated) {        _authenticated =NO;        _urlConnection = [[NSURLConnection alloc] initWithRequest:request delegate:self]; // 网上好多教程这句写的request写的是_request        _request = request; //网上好多教程这句代码忘记加了        [_urlConnection start];        return NO;    }    return YES;}#pragma mark - NURLConnection delegate- (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge{    if ([challenge previousFailureCount] == 0)    {        _authenticated = YES;        NSURLCredential *credential = [NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust];        [challenge.sender useCredential:credential forAuthenticationChallenge:challenge];    } else    {        [[challenge sender] cancelAuthenticationChallenge:challenge];    }}- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response{    // remake a webview call now that authentication has passed ok.    _authenticated = YES;    [self.webView loadRequest:_request]; //  self.webView替换成自己的webview    // Cancel the URL connection otherwise we double up (webview + url connection, same url = no good!)    [_urlConnection cancel];}// We use this method is to accept an untrusted site which unfortunately we need to do, as our PVM servers are self signed.- (BOOL)connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace *)protectionSpace{    return [protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust];}
