iOS–；为同一通知触发了两次UILocalNotification

如果我安排两个

UILocalNotification

s，并将它们设置为在完全相同的fireDate点火。然后在fireDate的设备上（这不是模拟器bug），

应用程序：didReceiveLocalNotification:

将触发4次（每次通知2次）。这是已知的bug吗？因为我找不到有关它的任何信息。

请将错误报告给

话虽如此，之前已经注意到，虽然模拟器中存在缺陷，但设备上似乎也存在缺陷

请参阅有关此SO问题的评论和答案：

在我的应用程序中尝试此功能：

-(IBAction)setRemind:(id)sender{

NSCalendar *calendar = [NSCalendar autoupdatingCurrentCalendar];

NSDateFormatter *dateFormatter2 = [[NSDateFormatter alloc] init];

[dateFormatter2 setDateFormat:@"YYYY-MM-dd HH:mm:ss"];

//Gets our picker
NSDate *selectedTime = [datePicker date];
strDate2 = [dateFormatter2 stringFromDate:selectedTime];
NSDate *Date=[dateFormatter2 dateFromString:strDate2];

NSDateComponents *dateComponents = [calendar components:(NSYearCalendarUnit | NSMonthCalendarUnit | NSDayCalendarUnit ) fromDate:Date];

// Set up the fire time
NSDateComponents *dateComp = [[NSDateComponents alloc] init];
[dateComp setDay:[dateComponents day]];
[dateComp setMonth:[dateComponents month]];
[dateComp setYear:[dateComponents year]];
[dateComp setHour:9];
[dateComp setMinute:00];
[dateComp setSecond:00];
[dateComp release];

NSDate *date = [calendar dateFromComponents:dateComp];
[self scheduleAlarmForDate:date message:txtDescri.text];

}


-(IBAction)scheduleAlarmForDate:(NSDate*)date message:(NSString*)msg
{

//====== TO SEE OLD NOTIFI=======
UIApplication *Ap = [UIApplication sharedApplication];
NSArray *arr = [Ap scheduledLocalNotifications];
NSLog(@"Old Notifications :>> %@",arr);

UIApplication* app = [UIApplication sharedApplication];
UILocalNotification *alarm = [[UILocalNotification alloc] init];

// Create a new notification
alarm.fireDate = date;
NSLog(@"fireDate IS >> %@", alarm.fireDate);
alarm.timeZone = [NSTimeZone localTimeZone];
alarm.alertBody = msg;
NSLog(@"msg IS >> %@",msg);
alarm.alertAction = @"Show";
alarm.repeatInterval = 0;
alarm.soundName = UILocalNotificationDefaultSoundName;
alarm.applicationIconBadgeNumber = 1;
[app scheduleLocalNotification:alarm];
 [alarm release];
} 

我希望这对你有帮助
