Question

我的问题是：我有一个TableVC，其中我有CustomCells。这些customCells具有各种标签，其中一个是时间标签。解析一个xml将获取timeLabel的文本。但是现在假设我使用静态内容，例如：下午2:45。是否有可能将此文本作为UILocalNotification的fireDate提供，并且当然它应该在上述时间触发。应该在点击“didSelectRowAtIndexPath”中的单元格时完成。或者这不可能做到？

是的，如果这是一个重复的问题，你不喜欢它，或者如果有一些拼写错误或任何相关的事请不要用投票标记它。我曾经看到人们玩这种廉价的噱头，并以不健康和不专业的方式使用他们所谓的声誉。

热烈欢迎你的相关答案。

谢谢!!!

修改我试过这件事

 NSString *str = cell.timeLabel.text;
    NSLog(@"str = %@",str);
    formatter = [[NSDateFormatter alloc]init];
    [formatter setDateFormat:@"MM/dd/yyyy hh:mm a"];
    NSTimeZone *gmt = [NSTimeZone timeZoneWithAbbreviation:@"GMT"];
    [formatter setTimeZone:gmt];
    date = [formatter dateFromString:str];

上面的cellForRowAtIndexPath

和

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{



    UILocalNotification *localNotif = [[UILocalNotification alloc] init];

    localNotif.fireDate = [NSDate dateWithTimeInterval:5 sinceDate:date];

    localNotif.timeZone = [NSTimeZone defaultTimeZone];
    localNotif.alertBody = @"You are notified";
    localNotif.soundName = UILocalNotificationDefaultSoundName;
    [[UIApplication sharedApplication]scheduleLocalNotification:localNotif];

}

NSDate *currentDate=[NSDate date];
NSString *dateStr=@"7:10 PM";
UILocalNotification *localNotification =[[UILocalNotification alloc]init];
NSTimeZone *gmt = [NSTimeZone timeZoneWithAbbreviation:@"GMT"];
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"hh:mm a"];
[dateFormatter setTimeZone:gmt];
[dateFormatter setDateFormat:@"yyyy-MM-dd"];

NSString *preFix=[dateFormatter stringFromDate:currentDate];
NSString *datetoFire=[NSString stringWithFormat:@"%@ %@",preFix,dateStr];

[dateFormatter setDateFormat:@"yyyy-MM-dd hh:mm a"];
[dateFormatter setDateStyle:NSDateFormatterShortStyle];
[dateFormatter setTimeStyle:NSDateFormatterShortStyle];
[dateFormatter setDateFormat:@"yyyy-MM-dd hh:mm a"];

NSDate *fireDate = [dateFormatter dateFromString:datetoFire];
fireDate=[fireDate dateByAddingTimeInterval:-(60*60*(5.5))];

NSLog(@"date is %@",fireDate);

// Cancel the previously scheduled notification, if any.
if (localNotification == nil) {
    return;
}

localNotification = [[UILocalNotification alloc] init];
localNotification.alertBody = @"Good Morning Buddies";
localNotification.alertAction = @"View";
localNotification.fireDate = fireDate;
localNotification.soundName = UILocalNotificationDefaultSoundName;
localNotification.applicationIconBadgeNumber++;
[[UIApplication sharedApplication] scheduleLocalNotification:localNotification];

根据Label的Text / Value调用UILocalNotification
