我正在使用 Web 服务并使用 sbjson 解析接收到的数据，如下所示：

NSDictionary *response = [[[NSString alloc]initWithData:data encoding:NSUTF8StringEncoding]JSONValue];

它运行良好，但使用包含二进制数据（应用程序/pdf）的 json 失败，我在控制台中得到了这个：

-JSONValue failed. Error trace is: (
    "Error Domain=org.brautaset.JSON.ErrorDomain Code=6 \"Invalid high character in surrogate pair\" UserInfo=0x1e0e1700 {NSLocalizedDescription=Invalid high character in surrogate pair}",
    "Error Domain=org.brautaset.JSON.ErrorDomain Code=6 \"Broken unicode character\" UserInfo=0x1e0e1740 {NSUnderlyingError=0x1e0e1720 \"Invalid high character in surrogate pair\", NSLocalizedDescription=Broken unicode character}",

)

现在我想知道如何在不移动到另一个 json 库的情况下解决它。还有其他人曾经处理过包括二进制在内的json吗？谢谢！

来自：json.org “JSON 是一种文本格式”。Base64 对二进制数据进行编码。

请参阅SO 问题“JSON 字符串中的二进制数据”
