iOS 10 以前本地推送通知：

  // [[UIApplication sharedApplication] registerUserNotificationSettings:settings];
  // // 通知重复提示的单位，可以是天、周、月
  // }

  UILocalNotification *notification = [[UILocalNotification alloc] init];
  // 设置触发通知的时间
  NSDate *fireDate = [NSDate dateWithTimeIntervalSinceNow:alertTime];
  NSLog(@”fireDate=%@”,fireDate);

  notification.fireDate = fireDate;
  // 时区
  notification.timeZone = [NSTimeZone defaultTimeZone];
  // 设置重复的间隔
  notification.repeatInterval = kCFCalendarUnitSecond;

  // 通知内容
  notification.alertBody = @”该起床了…”;
  notification.applicationIconBadgeNumber = 1;
  // 通知被触发时播放的声音
  notification.soundName = UILocalNotificationDefaultSoundName;
  // 通知参数

  notification.userInfo = userDict;

  // iOS8后，需要添加这个注册，才能得到授权
