AppDelegate didFinishLaunchingWithOptions launchOptions始终返回（空）

Question

我正在尝试使用完全关闭（终止）的应用程序获取计划的UILocalNotification ，因为方法didReceiveLocalNotification:没有被调用，所以我尝试使用以下代码：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
UILocalNotification *localNotification = [launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];
NSLog(@"LOCAL NOTIFICATION - %@",localNotification);
if (localNotification) {
    //HANDLE THE NOTIFICATION
}
return YES;

}

这就是我创建UILocalNotification ：

UILocalNotification * notificationRH = [UILocalNotification new];
notificationRH.fireDate = date;
notificationRH.repeatInterval = repetition;
notificationRH.alertBody = body;
notificationRH.alertAction = title;
notificationRH.hasAction = title ? 1 : 0;
notificationRH.timeZone = [NSTimeZone defaultTimeZone];
notificationRH.soundName = sounds ? UILocalNotificationDefaultSoundName : nil;
notificationRH.userInfo = @{@"test": title};

但是问题是方法上的launchOptions总是返回(null) ，并且在关闭应用程序时无法触发Notification。 有谁能帮助我吗？ 非常感谢！！

问题是您忘记了安排本地通知：
