有没有办法停止播放音频？喜欢播放/停止的东西？
-(IBAction)PlaySound:(id)sender{
audioTitle = [NSString stringWithFormat:@"Audio %@", audioInteger];
CFBundleRef mainBundle = CFBundleGetMainBundle();
CFURLRef soundfileURLREF;
soundfileURLREF = CFBundleCopyResourceURL(mainBundle, (CFStringRef) audioTitle, CFSTR ("mp3"), NULL);
UInt32 SoundID;
AudioServicesCreateSystemSoundID(soundfileURLREF, &SoundID);
AudioServicesPlaySystemSound(SoundID);
}
