小编Clo*_*ync的帖子

我正在使用这种方法:

NSUserNotification *notification = [[NSUserNotification alloc] init];
            notification.title = @"Title";
            notification.informativeText = @"body";
            notification.soundName = NSUserNotificationDefaultSoundName;

            [[NSUserNotificationCenter defaultUserNotificationCenter] deliverNotification:notification];

如何让它在3秒后超时？
