在我打开应用程序之前，本地通知不会停止发送

Question

在我打开应用程序之前，我的应用程序不会停止发送我在特定时间设置的通知。它会像我每2分钟那样发送给我一点提醒我......

• （void）applicationDidEnterBackground：（UIApplication *）application {

  NSCalendar * calendar3 = [NSCalendar currentCalendar]; NSDateComponents * components3 = [calendar3 components：（NSYearCalendarUnit | NSMonthCalendarUnit | NSDayCalendarUnit | NSHourCalendarUnit | NSMinuteCalendarUnit）fromDate：[NSDate date]]; [components3 setHour：21]; [components3 setMinute：30]; UIApplication * app3 = [UIApplication sharedApplication]; UILocalNotification * notifyAlarm3 = [[UILocalNotification alloc] init]; if（notifyAlarm3）{     notifyAlarm3.fireDate = [calendar3 dateFromComponents：components3];     notifyAlarm3.timeZone = [NSTimeZone defaultTimeZone];     notifyAlarm3.repeatInterval = NSDayCalendarUnit;     notifyAlarm3.soundName = @“not.wav”;     notifyAlarm3.alertBody = @“你好”;     [app3 scheduleLocalNotification：notifyAlarm3]; } }

• （void）applicationWillEnterForeground：（UIApplication *）application {
  UIApplication * app = [UIApplication sharedApplication]; NSArray * oldNotifications = [app scheduledLocalNotifications]; if（[oldNotifications count]＆gt; 0）{     [app cancelAllLocalNotifications]; } }

期待回应！
