Cocoa Touch - 加载 AVAudioPlayer

Question

我有这段代码可以播放声音，但第一次播放时需要 5 秒才能加载...

如何加快速度？

-(IBAction)playSound{ //play the cricket noise
 NSString *soundPath = [[NSBundle mainBundle] pathForResource:@"Cricket_Sound" ofType:@"mp3"];
 audioPlayer =[[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:soundPath] error:NULL];
 audioPlayer.delegate = self;
 [audioPlayer prepareToPlay];
 audioPlayer.numberOfLoops = 0;
 [audioPlayer play];
}

Answer 1

您可以尝试将以下代码部分放在viewDidLoad 中，以便audioPlayer 实例在被要求实际播放音频之前准备好播放：

NSString *soundPath = [[NSBundle mainBundle] pathForResource:@"Cricket_Sound" ofType:@"mp3"];
 audioPlayer =[[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:soundPath] error:NULL];
 audioPlayer.delegate = self;
 [audioPlayer prepareToPlay];
 audioPlayer.numberOfLoops = 0;
