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]> 0）{[app cancelAllLocalNotifications]; }}
期待回复！
