Global Variable

NSWorkspaceWillLaunchApplicationNotification

Posted when the Finder is about to launch an app.

Declaration

NSNotificationName NSWorkspaceWillLaunchApplicationNotification;

Discussion

The notification object is the shared NSWorkspace instance. In macOS 10.6 and later the userInfo dictionary contains the NSWorkspaceApplicationKey key with a corresponding instance of NSRunningApplication that represents the affected app.

In OS X v10.5 and earlier the userInfo dictionary contains the keys and values described in Table 1.

The system does not post this notification for background apps or for apps that have the LSUIElement key in their Info.plist file. If you want to know when all apps (including background apps) are launched or terminated, use key-value observing to monitor the value returned by the runningApplications method.
