How to play the macOS "Trash" system sound?-CodePudding

I found several macOS system sounds inside

/System/Library/Components/CoreAudio.component/Contents/SharedSupport/SystemSounds

including the trash sound when you delete a file in finder in dock/drag to trash.aif.

However I could not find an API to play any of these sounds. I would really prefer not to hardcode any file paths.

PS: An option would probably be to simply copy the sound to my own app bundle, but I also want to avoid that if possible (also licensing?).

CodePudding user response：

Import AudioToolbox framework and use AudioServicesPlaySystemSound function. The argument values are not documented and are subject to change the same as the hard coded paths. It should pass the app store review as it's not private API.

//drag to trash.aif
AudioServicesPlaySystemSound(0x10);

//poof item of dock.aif
AudioServicesPlaySystemSound(0xf);

The only documented values are:

CF_ENUM(SystemSoundID)
{
    kSystemSoundID_UserPreferredAlert   = 0x00001000,
    kSystemSoundID_FlashScreen          = 0x00000FFE,
        // this has been renamed to be consistent
    kUserPreferredAlert     = kSystemSoundID_UserPreferredAlert
};

Here is list of undocumented values
