在过去的几天里，我正在尝试将本地保存的声音记录上传到服务器（它使用 php 文件处理它并将其保存到服务器）。问题是我找不到这样做的方法。
在录制声音（AVAudioRecorder）时，它保存在“NSTemporaryDirectory()”中：
NSURL *temporaryRecFile = [NSURL fileURLWithPath:[NSTemporaryDirectory() stringByAppendingPathComponent:[NSString stringWithFormat:@"VoiceFile"]]];
现在，无论我在哪里检查答案都是使用ASIHTTPRequest。但问题是它在 ios6 中不受支持。
还有一些其他的库，但无论我如何尝试，都没有任何效果。如果有人可以帮助我，我会很高兴...
这是我的代码：
