Question

我正在使用以下代码进行本地通知

 for (int i=0;i<newBirthDates.count;i++)
{
    NSDate *date =[Formatter1 dateFromString:[newBirthDates objectAtIndex:i ]];
    NSComparisonResult result = [date compare:todaydate];
    if(result == NSOrderedSame)
    {
        UILocalNotification *localNotif = [[UILocalNotification alloc] init];
        localNotif.fireDate = date;
        localNotif.timeZone = [NSTimeZone defaultTimeZone];
        localNotif.alertBody = @"birthdate notification";
        localNotif.alertAction = @"View";

        localNotif.soundName = UILocalNotificationDefaultSoundName;
        localNotif.applicationIconBadgeNumber = 1;
        [[UIApplication sharedApplication] scheduleLocalNotification:localNotif];
    }
}
  newBirthdate is array with dates in it
  Formatter1 =MM/dd.

让我们说newbrithdate中的一个日期是18/3，所以我所做的就是更换我的电脑日期到17/3和11.59 pm然后我等待1分钟它转18/3但我没有得到任何通知我的模拟器中的时间总是与我的电脑时间相同。

您将格式化的日期字符串存储在数组中（以MM / dd格式）并将其转换回日期以设置通知。

让我们做一个简单的检查!!

NSDateFormatter *Formatter1 = [[NSDateFormatter alloc]init];
Formatter1.dateFormat =@"MM/dd";

NSDate *today = [NSDate date];// take current date
NSString *initialDateString =[Formatter1 stringFromDate:today]; // formatted date string(in MM/dd)


NSDate *dateFromFormatter = [Formatter1 dateFromString:initialDateString]; // Date from the formatted string(In your case taking from array)
NSString *finalDateString = [Formatter1 stringFromDate:dateFromFormatter];// formatted string from new date

// lets take a look wether both are same
NSLog(@"Initial date string: %@",initialDateString);
NSLog(@"Final date string  : %@",finalDateString);
// Both date strings are same

NSLog(@"Actual date    : %@",today);
NSLog(@"Formatted date : %@",dateFromFormatter);
//But see both dates are entirely different

输出

初始日期字符串：03/18
截止日期字符串：03/18
实际日期：2013-03-18 12:15:45 +0000
格式化日期：2000-03-17 18:30:00 +0000

那你怎么得到通知？
