I've created an application with a button "Exit" and I've connected
it with
the method:
- (IBAction)exitApp:(id)sender
{
// TODO
}
Now my question is: "Which call I have to do to quit my application
instead
of // TODO?"
Is there a NSsomething to call?
[[NSApplication sharedApplication] terminate:self];
Also, in this simple case, the button can directly target the
application object with the terminate: action. That is, the above -
exitApp: method is an action method. So is -[NSApplication
terminate:]. It is an action method for the very purpose of being
connected to UI elements via the target-action mechanism.
Cheers,

Cheers, -- Uli Kusterer "The Witnesses of TeachText are everywhere..." http://www.zathras.de And for anyone curious about the same question in relation to the iPhone OS, two comments come to mind: a) you're not supposed to quit your own application; the user is in charge and can hit the home button if he/she wants to quit your application b) still, if you really want to programmatically quit your application, you can try the analogous [[UIApplication sharedApplication] performSelector: @selector(terminate)]; It works, but the final animation that an application goes through when the application quits to the home screen (the zooming effect) does not happen, which might confuse the user into thinking that your application crashed.
