如何在iPhone应用程序中播放声音(How to play sounds in iPhone app)

我是这个非常令人困惑的Objective-C游戏的初学者。

每次按下某个按钮，我都想播放非常短的音效。

我怎样才能做到这一点？

我可以使用mp3文件吗？ 或者我必须转换为wav？

I am a beginner in this very confusing Objective-C game.

I would like to play a very short sound effect every time a certain button is pushed.

How can I do this?

Can I use an mp3 file? Or will I have to convert to wav?

您可以使用系统声音服务播放短音：

CFBundleRef mainBundle = CFBundleGetMainBundle(); CFURLRef soundFileURLRef = CFBundleCopyResourceURL(mainBundle, CFSTR("filename"), CFSTR("aiff"), NULL); SystemSoundID soundId; AudioServicesCreateSystemSoundID(soundFileURLRef, &soundId); AudioServicesPlaySystemSound(soundId); CFRelease(soundFileURLRef)

支持.caf，.aiff和.wav格式。
