Question

我正在尝试使用AudioToolBox框架点击按钮播放一个wav文件。没有抛出任何错误，但声音没有播放。

-(IBAction)buttonPressed
{

  NSString *path;
  NSURL *url;
  AVAudioPlayer *player;
  NSLog(@"Hai");
  path = [[NSBundle mainBundle] pathForResource:@"sound" ofType:@"wav"];
  url=[NSURL fileURLWithPath:path];
  player=[[AVAudioPlayer alloc]initWithContentsOfURL:url error:NULL];
  [player setVolume:5.0];
  [player play];
 }

还试过这段代码

NSString *path = [NSString stringWithFormat:@"%@%@", [[NSBundle mainBundle] resourcePath], @"censor-beep-01.wav"];

SystemSoundID soundID;
NSURL *filePath = [NSURL fileURLWithPath:path isDirectory:NO];
//Use audio sevices to create the sound
AudioServicesCreateSystemSoundID((__bridge CFURLRef)filePath, &soundID);
//Use audio services to play the sound
AudioServicesPlaySystemSound(soundID);

Answer 1

在头文件中设置AVAudioPlayer框架..并声明AVAudioPlayer *播放器;在.h文件中

@property（非原子，保留）AVAudioPlayer *播放器; 在按钮动作AVAudioPlayer *播放器中合成并删除此行; 你应该在.h文件中声明。
