为iOS投冰源客户端
我一直在试图为ios创build一个用于投冰的源代码客户端。 我已经能够连接使用asyncsocket连接到套接字。 我也能够写入数据到服务器。 icecastconfiguration是为mp3格式完成的。 但写入服务器的MP3文件已损坏。 我正在提供一些代码片段。

我是否需要更改写入服务器的格式？
你不发送MP3数据，你正在发送AAC或M4A数据。 我不相信Icecast支持M4A。 你真的使用Icecast或其他服务器？
对于AAC，您的Content-Type标头是错误的。 尝试audio/aac ， audio/aacp ， audio/mp4或audio/mpeg4-generic 。
另外，您只需要一个User-Agent头，您应该select与您正在编写的软件相匹配的内容，而不是复制其他人的内容。 将来，可能需要对代码进行协议调整，而且只有在使用自己的用户代理string时才有可能。
