objective-c - SBJSON 失败，包含二进制数据的 json

Question

我正在使用 Web 服务并使用 sbjson 来解析接收到的数据，如下所示:

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

它运行良好但失败了包含二进制数据的 json (application/pdf)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。还有其他人处理过包括二进制在内的 json 吗？谢谢!

发件人:json.org “JSON 是一种文本格式”。将二进制数据进行Base64编码。
