UILocalNotification如何在屏幕锁定时显示应用程序图标

Question

我正在创建这样的本地通知：

UILocalNotification * notification = [[UILocalNotification alloc] init];
notification.alertBody = @"Alert body";
notification.alertAction = @"Yes";
notification.fireDate = [NSDate date];

[[UIApplication sharedApplication] presentLocalNotificationNow:notification];

如果在手机被锁定时加注，则只有“滑动解锁”滑块之前显示的短信。我知道可以显示一些带警报的图标。我的应用程序的图标大小为57 x 57。 有任何建议怎么做？
