How can my app know that Finder has started? Is there any event that could help with this?
I thought about enumerating processes and look for Finder but this seems too heavy to do every X seconds. Is there any other way?
回答1:
You can observe the notifications that NSWorkspace posts to its notification center (-[NSWorkspace notificationCenter]). For example, it posts NSWorkspaceDidLaunchApplicationNotification when a GUI app is launched. That notification's userInfo dictionary has, under the key NSWorkspaceApplicationKey, an instance of NSRunningApplication for the newly-launched app. You can check the bundleIdentifier of that to see if it equals "com.apple.finder".
