cocoa-touch - Cocoa Touch - 加载 AVAudioPlayer

Question

我有这段代码可以播放声音，但是第一次播放它需要 5 秒钟才能加载...

我怎样才能加快速度？

-(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入其中，viewDidLoad以便在要求audioPlayer实例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;
