Question

I am wondering if there is some way to run a function every minute in Cocoa. I, personally, will be using this for saving content as the user types it in case they quit – But I have seen this effect also used in Twitter clients. When the user keeps the window open, it will auto-update every x minutes without input from the user. It seems as if this is common, and the language allows it, I just can’t seem to find documentation on it.

Thanks for any help!

A better solution would be to be the text view’s delegate, and respond to textDidChange: by creating the non-repeating timer (if you have not done so already or it has already fired) and setting its fire date to X seconds in the future. Then, the user loses no more than X seconds’ worth of work, not up to one minute, and the timer is not firing when the user has not typed anything.
