iPhone：AVAudioPlayer是否支持.wav格式？

Question

我将在我的应用程序中使用.wav音频文件。

是否AVAudioPlayer支持.wav文件格式？

还有哪些其他格式支持AVAudioPlayer？

Answer 1

是的，AVAudioPlayer为您提供播放.wav文件的可能性。

这是很简单的：

// in the corresponding .h file: 
// @property (nonatomic, retain) AVAudioPlayer *player; 

// in the .m file: 
@synthesize player; // the player object 

NSString *soundFilePath = 
      [[NSBundle mainBundle] pathForResource: @"sound" 
              ofType: @"wav"]; 

NSURL *fileURL = [[NSURL alloc] initFileURLWithPath: soundFilePath]; 

AVAudioPlayer *newPlayer = 
      [[AVAudioPlayer alloc] initWithContentsOfURL: fileURL 
                error: nil]; 
[fileURL release]; 

self.player = newPlayer; 
[newPlayer release]; 

[player prepareToPlay];
