How to properly quit application, call exit(0)?

Question

I'm not sure which is the right way, right now I'm just calling exit(0) when a user clicks on the exit button.

Don't forget to title your button “Quit”, not “Exit”. – Vas

Answer 1

Use NSApplication's terminate method. For example:

[NSApp terminate:self]

Documentation is available here.

Answer 2

The previously given answer is deprecated since 10.10 and this question is the first thing that turns up for cocoa quit application, so use this instead (Swift):

NSApplication.sharedApplication().terminate(self)

Note: As of now it's the following:

NSApplication.shared().terminate(self)

What's deprecated? The use of NSApp? NSApp still appears to be available and isn't marked as deprecated in the documentation… – Bifocals

Because I just had to do this again: the original way to do it now yields: static member 'sharedApplication' cannot be used on instance of type 'NSApplication'. PS: Note that I wrote the comment above when Swift was still quite unstable, and especially Xcode was quirky as hell. So the error message might have been different at the time. – Shanklin

Answer 3

I always terminate App the safe way.

[NSApp performSelector:@selector(terminate:) withObject:nil afterDelay:0.0];

This will put the event in the next loop.
