Я реализую приложение на основе аудио, в котором мне нужно проигрывать как аудио приложения, так и ipod auido.Когда я пытаюсь запустить свое приложение, я получаю сообщение об ошибке: 

ld: framework not found AudioUnit
collect2: ld returned 1 exit status
Command /Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/llvm-gcc-4.2 failed with exit code 1

мой код контроллера представления выглядит следующим образом:

.h файл: 

 #import <UIKit/UIKit.h>

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


 @interface AudioViewController : UIViewController     <AVAudioPlayerDelegate,MPMediaPickerControllerDelegate>
{
     UIButton *musicButton;
     UIButton *soundButton;
     AVAudioPlayer *audioPlayer;
     MPMusicPlayerController *musicPlayerController;
}
@property (nonatomic, retain)  UIButton *musicButton;
@property (nonatomic, retain)  UIButton *soundButton;

Я использую FrameWorks, 

1. AuidoUnit.framework.
2. AVFoundation.framework.
3. MediaPlayer.framework.
4. UIKit.framework.
5. Foundation.framework.
6. CoreGraphics.framework.
7. CoreData.framework.

Ребята, пожалуйста, посмотрите на это и дайте мне знать, что мне не хватает.

Заранее спасибо, Чандра.

Попробуйте добавить CoreAudio.framework и AudioToolbox.framework в список фреймворков.

А также удалить AudioUnit.framework

В моем случае, добавив Accelerate.framework, помимо AudioToolbox.framework и CoreAudio.framework, здание удалось. Вы также можете найти это полезным.
