我一直在使用以下代码 
  
  
 
AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc]initWithRequest:request]; operation.allowsInvalidSSLCertificate=YES;
现在我将AFNetworking更改为2.0的最新版本.使用AFHTTPRequestOperation,operation.allowsInvalidSSLCertificate不再工作.根据我使用的文件
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager]; manager.securityPolicy.allowInvalidCertificates = YES;
我的请求代码是
AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc]initWithRequest:request];
[operation  setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation,id responSEObject) {
    NSLog (@"success: %@",operation.responseString);
}
                                  failure:^(AFHTTPRequestOperation *operation,NSError *error) {
                                      NSLog(@"error: %@",error.description);
                                  }
 ];
[operation start];
[operation waitUntilFinished]; 
 但是,这对于需要证书的HTTPS不起作用.我该怎么办才能使这项工作?
解决方法
 我在[操作开始之前]添加以下代码解决了这个问题; 
  
  
 
        AFSecurityPolicy *sec=[[AFSecurityPolicy alloc] init]; [sec setAllowInvalidCertificates:YES]; operation.securityPolicy=sec;
这是因为AFHTTPRequestOperationManager未连接到AFHTTPRequestOperation.所以设置管理员的安全证书在请求操作时不能做魔术.所以必须初始化并分配一个到AFHTTPRequestOperation.
希望这个帮助有人:)
