ios - 在iPhone iOS中播放简单的WAV文件

Question

我正在尝试使用AudioToolBox框架单击一个按钮来播放wav文件。没有引发任何错误，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];
 }

也尝试过此代码

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 * player;在.h文件中

@property(非原子的，保留)AVAudioPlayer * player;
在按钮 Action AVAudioPlayer * player中合成并删除此行；
您应该在.h文件中声明。
