同步运行时,AFNetworking永远不会完成

在有人发送线程告诉我这不是最佳做法之前,有充分的理由在这种情况下我没有使用异步方法。

我正在尝试强制我的AFNetworking库以某种方法调用的同步模式运行(已被分解)。

这是我的(黑客)片段:

    NSURL *url = [NSURL URLWithString:_apiBaseUrl];
    AFHTTPClient *client = [AFHTTPClient clientWithBaseURL:url];
    NSMutableURLRequest *request = [client requestWithMethod:@"POST" path:path parameters:nil];

    NSDictionary *requestDict = [NSDictionary dictionaryWithObjects:@[@"2.0", path, params, [NSNumber numberWithInt:(int)[[NSDate date] timeIntervalSince1970]]] forKeys:@[@"jsonrpc", @"method", @"params", @"id"]];

    NSString *requestBody = [requestDict JSONString];

    NSLog(@"requestBody: %@", requestBody);

    // Set the request body
    [request setHTTPBody:[requestBody dataUsingEncoding:NSASCIIStringEncoding]];
    AFJSONRequestOperation *operation = [AFJSONRequestOperation JSONRequestOperationWithRequest:request success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON) {

        // Do something with the success (never reached)
        successBlock(request, response, JSON);

    } failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, id JSON) {
        failureBlock(request, response, error, JSON);
    }];

    if (queue == 1) {
        [self.operationArray addObject:operation];
    }
    else {
        [operation waitUntilFinished];
        successBlock(nil, nil, nil);            
        //[operation start];

    }

当运行该方法并且队列参数强制该方法为waitUntilFinished时,永远不会到达成功块,也不是下一行。如果我使用start方法,它可以正常工作。
