ios 自签证书，webview加载https

首先如果你的证书是自签的，那么你的webview是是不是不能加载https的网址。如果是，且出现了如下的问题。那么就请接着看下去.

解决这个问题的办法，代码如下：

BOOL _Authenticated;

NSURLRequest * _FailedRequest; (两个全局变量)

- (void)createWebView {

_webview = [[UIWebView alloc] initWithFrame:CGRectMake(0, 0, kScreenW, kScreenH)];

_webview.delegate = self;

[self.view addSubview:_webview];

NSString * string = [NSString stringWithFormat:@"%@%@",baseRequest, self.urlString];

NSURL * url = [NSURL URLWithString:string];

_FailedRequest = [[NSURLRequest alloc] initWithURL:url cachePolicy:NSURLRequestReloadIgnoringLocalCacheData timeoutInterval:30.f];

[_webview loadRequest:_FailedRequest];

}

#pragma UIWebViewDelegate

- (void)webViewDidStartLoad:(UIWebView *)webView {

NSLog(@"webview开始加载！");

}

- (void)webViewDidFinishLoad:(UIWebView *)webView {

NSLog(@"webview加载完成！");

}

-(BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request  navigationType:(UIWebViewNavigationType)navigationType {

BOOL result = _Authenticated;

if (!_Authenticated) {

_FailedRequest = request;

NSURLConnection *urlConnection = [[NSURLConnection alloc] initWithRequest:request delegate:self];

[urlConnection start];

}

return result;

}

#pragma NSURLConnectionDelegate

-(void)connection:(NSURLConnection *)connection willSendRequestForAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge {

if ([challenge.protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust]) {

NSString * string = [NSString stringWithFormat:@"%@%@",baseRequest, self.urlString];

NSURL* baseURL = [NSURL URLWithString:string];

if ([challenge.protectionSpace.host isEqualToString:baseURL.host]) {

[challenge.sender useCredential:[NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust] forAuthenticationChallenge:challenge];

}

}

[challenge.sender continueWithoutCredentialForAuthenticationChallenge:challenge];

}

-(void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)pResponse {

_Authenticated = YES;

[connection cancel];

[_webview loadRequest:_FailedRequest];

}。

到这里，运行你的demo试试吧，奇迹会发生！
