在过去的几天中，我尝试将本地保存的声音记录上传到服务器(将其与php文件一起处理并将其保存到服务器)。
问题是我找不到解决办法。
录制声音(AVAudioRecorder)时，它保存在“NSTemporaryDirectory()”中:
NSURL *temporaryRecFile = [NSURL fileURLWithPath:[NSTemporaryDirectory() stringByAppendingPathComponent:[NSString stringWithFormat:@"VoiceFile"]]];
现在，到处检查的答案都是使用ASIHTTPRequest。
但问题是ios6不支持它。
还有其他一些库，但是无论我如何尝试，都无济于事。
如果有人可以帮助我，我会喜欢的。
这是我的代码:

最佳答案
这行代码对我来说很好
现在我已经将整个代码发布到进行记录，保存，播放并发布到服务器
