ios项目绕过证书访问https程序

如果是单个的webview或者request请求，在请求的文件h中直接实现NSURLConnectionDelegate，并在m中添加下列实现下列两个方法：

 

 - (BOOL)connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace *)protectionSpace {
     return [protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust];
 }

 - (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge {
     if ([challenge.protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust])
         //if ([trustedHosts containsObject:challenge.protectionSpace.host])
             [challenge.sender useCredential:[NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust]
                  forAuthenticationChallenge:challenge];
     [challenge.sender continueWithoutCredentialForAuthenticationChallenge:challenge];
 }

 上述方法很不爽的是每个请求的地方都要加。

 

如果项目中用到了three20，直接修改“TTRequestLoader.m”即可，这个文件本身就已经实现了NSURLConnectionDelegate，

 

修改如下，只改这一个地方就行，处处可用。
