See applicationShouldTerminate:
-
(NSApplicationTerminateReply)applicationShouldTerminate:(NSApplication
*)sender
Invoked from within the terminate: method immediately before the
application terminates. sender is the NSApplication to be terminated.
The value returned should be one of the values defined in Constants.
For compatibility reasons, a return value of NO is equivalent to
NSTerminateCancel, and a return value of YES is equivalent to
NSTerminateNow.
See Also: terminate:,
applicationShouldTerminateAfterLastWindowClosed:,
applicationWillTerminate:
or applicationWillTerminate:
- (void)applicationWillTerminate:(NSNotification *)aNotification
Sent by the default notification center immediately before the
application terminates. aNotification is always an
NSApplicationWillTerminateNotification. You can retrieve the
NSApplication object in question by sending object to aNotification.
Put any necessary cleanup code in this method.
The applicationWillTerminate: method does not get called for logout for
power off. See NSWorkspaceWillPowerOffNotification, which is sent for
these events.
See Also: applicationShouldTerminate:, terminate:
In
http://developer.apple.com/techpubs/macosx/Cocoa/Reference/
ApplicationKit/ObjC_classic/Classes/NSApplication.html
Implement applicationShouldTerminate: or -applicationWillTerminate: to
implement a close, save, cancel or whatever panel.
NSData and NSString documentation explains how to read and write
strings or arbitrary data.
There is an example in "Cocoa Programming" that implements a
multi-document application without using NSDocument. It shows how to
use -applicationWillTerminate: etc. There is also the TextEdit sampel
already on your hard disk. It includes useful code.
