macOS Check for Update Function (SOLVED)

Hi,
Does anyone know how to write a check for updates script? Or know where i could find an example?
Just the back end like
- (IBAction)updateid)sender {
//update script
}
ANYTHING HELPS!

Ok

Thanks, i will try this out

Does not seem to work

The framwork does not seem to work with 10.5, has anyone gotten it to work? it is a coca app

I should have been more specific

yes, thank you. I should have been more specific, I can not get the class to show up in interface builder for 10.5. i dont know if im looking in the wrong spot or not, but i go to file-> read class file, then when i click on UUpdater.h it does not show up.

Never Mind

Sorry, i had a brain fart, i got it all taken care of
