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！
