How can I play a sound using Cocoa-Applescript in Xcode?

Check out the NSSound Class Reference. You can add a property for the sound and initialize it with something like:

set mySound to current application's NSSound's soundNamed_("your sound name")

The system will check for an installed sound file in the Sounds folders, and then in your application bundle if it is not found (note that the extension is not used). You can then play it by using the play method:

mySound's play()

Also note that if you are going to use one of the pre-installed sounds, you can assign a sound for the button in the Attributes Inspector in the Interface Editor.

If you could use one of the built-in sounds it would be easier, just

on playSound_(sender)

tellclass"NSSound"of current application

set soundInstance to its soundNamed_("Pop")

end

soundInstance's setVolume_(1.0)

soundInstance's |play|()

end

Just put the sound name you want to use in place of Pop

If you have to use the sound file then first you need to know where it is. The easiest is to have it as part of the bundle then you can use the pathToResource:ofType: method that finds files of a given type in the Resourse folder of the applications bundle.

So

tell class "NSBundle" of current application

tell its mainBundle

set soundFilePath to its pathForResource_ofType_("click", "aiff")

end tell

end tell

gets the sound file name in soundFilePath

then to play it first load it

tell class "NSSound" of current application

set soundInstance to its alloc()'s initWithContentsOfFile_byReference_(soundFilePath, true)

end tell

then play it as above

soundInstance's setVolume_(1.0)

soundInstance's |play|()

I beleive that should do it.

Never realized the system would check in the application's bundle for a non-standard sound file name, That sure does simplify things!

Yep - it looks like it only searches the /Library/Sounds and ~/Library/Sounds folders, but using the soundNamed: method replaces the statement(s) to get the resource in the bundle. You can still use paths or URLs if you want, though.

clicksound is not being set, most likely it is not finding the click.aiff file.

As a test change "click" to "Pop" and see if it works. Pop is one of the default sounds. If it works then you know the problem is not being able to find your sound file.

In cases like this testiog to make sure the class was set by doing somehting like

if clicksound is equal to missing value then

display alert "missing"

else

clicksound's play()

end

is a good habit to get into.

You might want to check if the sound is actually being found. Also, what kind of sound file is it? The documentation specifies that the sound file needs to be .wav or .aiff (with two 'f's).
