I'm trying to write an app where I need to accept keypresses, and call
a function whenever the user has stopped typing (or when there is a
specified delay between keystrokes).
How do I measure the time between two keystrokes?
Measuring the time between keystrokes (or events of any other kind) is
easy. Each keystroke generates an NSEvent and NSEvent has a -
timestamp method.
The real problem is that you want to do something when there _hasn't_
been an event for a certain time period. For that, I recommend that
you schedule an NSTimer, and keep pushing back its firing time each
time you get a keystroke.
