将AVAudioRecorder发送到服务器iOS [英] Sending AVAudioRecorder to server iOS
本文介绍了将AVAudioRecorder发送到服务器iOS的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我在过去几天尝试将一个本地保存的sounde记录上传到服务器（用一个php文件处理它并将其保存到服务器）。
问题是我找不到办法做到这一点。
I am trying for the past few days to upload a locally saved sounde record to a server (which handels it with a php file and saves it to the server). the problem is that I can't find a way to do that.
录制声音（AVAudioRecorder）时，它保存在NSTemporaryDirectory（） ：
While recording the sound (AVAudioRecorder) it saves at a "NSTemporaryDirectory()":
NSURL *temporaryRecFile = [NSURL fileURLWithPath:[NSTemporaryDirectory() stringByAppendingPathComponent:[NSString stringWithFormat:@"VoiceFile"]]];
现在，我检查答案的地方是使用 ASIHTTPRequest 。
，但问题是它在ios6中不受支持。
Now, everywhere I checked the answer was to use ASIHTTPRequest. but the problem is that it is not supported in ios6.
还有一些其他的库，但无论我尝试什么和如何都没有任何作用。
我很乐意，如果有人可以帮助我...
There are some other libraries for it but nothing works no matter what and how I try. I would love it if someone could help me...

ViewController。 m 包括我用图书馆进行的一些测试，例如 STHTTPRequest 和AFNetworking
The ViewController.m includes some test I have made with libraries such as STHTTPRequest and AFNetworking
推荐答案
这行代码对我很有用
现在我发布了我的整个代码用于录制，保存，播放和播放发布到服务器
now I have post my whole code for Record,save,play & post to server
