(iphone) 如何使用 AVAudioPlayer 顺序播放声音？

Question

I'd like to play multiple sound sequentially.
The sound data will be available via NSData.
(to be more precise, I'm going to play different sound whenever scrollViewDidEndScrolling is called, and stop previous sound if it is still playing)

Do I need to alloc/init AVAudioPlayer for every sequential sound?
If alloc/init/release AVAudioPlayer isn't a big deal, I could do that but I'm not sure

Answer 1

If using the higher-level AVAudioPlayer, then yes, you'd need to instantiate (alloc/init) an AVAudioPlayer for each.

Yet, the "expensive" part (time-wise) is prepareToPlay - which you could call in a separate thread, thus hopefully by the time you come to play any given sound, it will be fully ready to play.
