为什么Objective-C要将JSON值转换成ASCII字符码的散列?

从浏览器向iPhone发送JSON聊天信息时:

    {"content":"Hi"}

iPhone接收:

    {"content":{"0":72,"1":105,"length":2}}

要重现此问题,请首先安装节点.js&redis。然后:

• 获取代码:

  git clone git://github.com/acani/acani.git
  cd acani
  git submodule update --init
  

• http://github.com/acani/acani-node :

  node acani-node-server.js # run node.js chat server
  # open index.html in a Google Chrome or Firefox and follow instructions.
  

• http://github.com/acani/acani-chat/tree/master/Lovers2/ ,并将LoversAppDelegate.m更改为最初加载ChatViewController而不是HomeViewController。

  homeViewController = [[HomeViewController alloc] init]; # comment out this line
  # change the next line to:
  navigationController = [[UINavigationController alloc] initWithRootViewController:[[ChatViewController alloc] init]];
  # Then, build & run.
