NS任务控制通知

Question

是否可以在Cocoa应用程序中接收启动Mission Control的通知？

我尝试了以下但没有成功：

- (void)applicationDidFinishLaunching:(NSNotification *)notification {

    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(notify:) name:NSWorkspaceActiveSpaceDidChangeNotification object:nil];
}

- (void)notify:(NSNotification *)notifcation {
    NSLog(@"mission control called");
}
