当另一个可可应用程序终止时，一个Cocoa应用程序通知

Question

Suppose there are two cocoa apps APP1 and APP2. I want APP2 to be notified when APP1 terminates. I want some callback function registered with APP2 which will be called as soon as APP1 terminates. How can I achieve this? Any sample code will be highly appreciated.

Answer 1

You can observe the NSWorkspaceDidTerminateApplicationNotification . Its userInfo dictionary contains details about which application was terminated (an NSRunningApplication object).

Answer 2

You certainly looking for NSDistributedNotificationCenter .

Whenever you want to send a notification from One app to Other, just like XCode3.2 and Interface Builder were sending notifications, use NSDistributedNotificationCenter .

This documentation contains sample code such as DockTile, that will come handy to you.
