в моей таблице ViewController на
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
я нажимаю свой viewController
[self.navigationController pushViewController:[[[UIViewController alloc] initWithNibName:@"myViewController" bundle:nil] autorelease] animated:YES];
в myViewController я импортирую AVFoundation и добавляю через IB три кнопки для воспроизведения / паузы / остановки песни
myViewController.h
#import <UIKit/UIKit.h>
#import <AVFoundation/AVFoundation.h>
@interface fotos : UIViewController <AVAudioPlayerDelegate> {
AVAudioPlayer *player;
}
@property (nonatomic, retain) AVAudioPlayer *player;
-(IBAction)play:(id)sender;
-(IBAction)pause:(id)sender;
-(IBAction)stop:(id)sender;
и я реализовал таким образом
myViewController.m
@implementation fotos
@synthesize player;
- (void)viewDidLoad {
[super viewDidLoad];
NSString *filePath = [[NSBundle mainBundle] pathForResource:@"peter"
ofType:@"mp3"];
NSURL *fileURL = [[NSURL alloc] initFileURLWithPath:filePath];
player = [[AVAudioPlayer alloc] initWithContentsOfURL:fileURL error:nil];
player.delegate = self;
[player prepareToPlay];
[filePath release];
[fileURL release];
}
-(IBAction)play:(id)sender {
if(!player.playing)
{
[player play];
}
}
-(IBAction)pause:(id)sender {
[player pause];
}
-(IBAction)stop:(id)sender {
[player stop];
}
Я подключил свое действие в IB, но когда я пытаюсь воспроизвести мой файл, я получаю

terminate called after throwing an instance of 'NSException'
Я также пытался играть в viewDidLoad, но ничего.
Есть предложения?
Спасибо в
