ios – 如何使用AFNetworking允许https连接？

我已经设置了AFNetworking,但它不接受https网址.如何让AFNEtworking通过ssl进行连接.

我有以下代码：

NSMutableURLrequest *apirequest =
[self multipartFormrequestWithMethod:@"POST"
                                path: pathstr
                          parameters: params
           construcTingBodyWithBlock: ^(id <AFMultipartFormData>formData)
           {
               //TODO: attach file if needed
           }];



AFJSONrequestOperation* operation = [[AFJSONrequestOperation alloc] initWithrequest: apirequest];
[operation setCompletionBlockWithsuccess:^(AFhttprequestOperation *operation,id responSEObject) {
    //success!
    completionBlock(responSEObject);
} failure:^(AFhttprequestOperation *operation,NSError *error) {
    //failure :(

    NSLog(@"%@",error);
    completionBlock([NSDictionary DictionaryWithObject:[error localizedDescription] forKey:@"error"]);
}];

[operation start];

operation.securityPolicy.allowInvalidCertificates = YES;
