现在，iPhone 3.0 SDK是公共的，我想我可以问那些你已经玩了3.0 SDK这个问题。我想在我的应用程序中录制音频，但我想使用AVAudioRecorder而不是像SpeakHere所示的示例那样采用较旧的录制方式。 iPhone开发中心没有任何关于如何做到这一点的例子，只能参考类。我是iPhone开发的新手，所以我正在寻找一个简单的示例让我开始。提前致谢。如何使用AVAudioRecorder在iPhone上录制音频？
其实，有根本没有例子。 这是我的工作代码。录制是由用户在navBar上按下按钮触发的。 录音使用cd质量（44100个采样），立体声（2个通道）线性pcm。注意：如果您想使用其他格式，尤其是编码格式，请确保您完全理解如何设置AVAudioRecorder设置（仔细阅读音频类型文档），否则您将永远无法正确初始化它。还有一件事。在代码中，我没有展示如何处理计量数据，但可以轻松搞定。 最后，请注意截至撰写本文时AVAudioRecorder方法deleteRecording崩溃了您的应用程序。这就是我通过文件管理器删除记录文件的原因。录制完成后，我使用KVC将录制的音频保存为当前编辑的对象中的NSData。

好吧，所以我得到的答案帮助我在正确的方向，我非常感谢。它帮助我弄清楚如何真正在iPhone上的记录，但我想我也将包括一些有用的代码，我从iPhone参考图书馆有：
我用这个代码，并把它添加到avTouch例子相当容易。使用上面的代码示例和参考库中的示例，我能够很好地实现这一目标。
下面的链接，你可以找到与AVAudioRecording记录有用的信息。在第一部分“使用音频”的链接中，有一个名为“AVAudioRecorder Class录音”的锚点，可以引导您进入该例子。
它真的很有帮助。我唯一的问题是记录后创建的声音文件的大小。我需要减小文件大小，所以我做了一些设置更改。
NSMutableDictionary *recordSetting = [[NSMutableDictionary alloc] init];
[recordSetting setValue :[NSNumber numberWithInt:kAudioFormatAppleIMA4] forKey:AVFormatIDKey];
[recordSetting setValue:[NSNumber numberWithFloat:16000.0] forKey:AVSampleRateKey];
[recordSetting setValue:[NSNumber numberWithInt: 1] forKey:AVNumberOfChannelsKey];
文件大小从360kb减少到只有25kb（2秒记录）。
虽然这是一个回答的问题（和慈祥的老人），我决定张贴其他人发现很难找到好的工作（开箱）播放和录制比如我的完整的工作代码 - 包括编码，PCM通过扬声器播放，写在这里提交是：

希望这将帮助一些你们的。
我一直在试图让这段代码在过去的2个小时里工作，虽然它在模拟器上没有显示错误，但是在设备上有一个错误。
事实证明，至少在我的情况，从目录中附带的错误使用（包）：
NSURL *url = [NSURL fileURLWithPath:[NSString stringWithFormat:@"%@/recordTest.caf", [[NSBundle mainBundle] resourcePath]]];
这是不可写或者这样的事情...什么都有，除了这个事实没有错误prepareToRecord
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *recDir = [paths objectAtIndex:0];
NSURL *url = [NSURL fileURLWithPath:[NSString stringWithFormat:@"%@/recordTest.caf", recDir]]
现在就像一个魅力：失败...
因此，我被取而代之。
希望这可以帮助别人。
我上传了一个示例项目。你可以看看。

十分感谢@Massimo卡法洛和Shaybc 我是能够实现的任务
下面的iOS 8：
Record audio & Save
Play Saved Recording
1.新增 “AVFoundation.framework” 到您的项目
在.h文件中
2.添加以下import语句 'AVFoundation/AVFoundation.h'。
3.Define “AVAudioRecorderDelegate”
4.Create实录布局，播放按钮和其行动methids
5.Define记录器和播放等
下面是完整的示例代码这可能会帮助你。

#import <UIKit/UIKit.h>
#import <AVFoundation/AVFoundation.h>

真棒，我已经迫不及待要将此代码到我的项目。非常感谢你的回答，昨晚让我疯狂，试图让它独立工作，但我确实很好地学习了这门课。 :) – 2009-06-18 15:24:19
我认为我已经接近让你的代码工作，但我正在努力与委托的东西。我对Objective C非常陌生，但仍然没有找到正确的方法来做这样的事情。我有我的委托试图实现NSObject，但我不认为我做对了。发布委托代码也会太麻烦吗？谢谢。 –
