ios - 从选择表格单元格设置本地通知

Question

其实这个问题已经被问了很多次了。但我对这些感到困惑。这个我试过了。

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    if([[cell.btn backgroundImageForState:UIControlStateNormal]isEqual:[UIImage imageNamed:@"unchecked.png"]])
    {
        [cell.btn setBackgroundImage:[UIImage imageNamed:@"checked.png"] forState:UIControlStateNormal];

    UILocalNotification *reminderNote =[[UILocalNotification alloc]init];
    reminderNote.soundName = @"music.mp3";
    [[UIApplication sharedApplication] scheduleLocalNotification:reminderNote];
    reminderNote.alertBody = @"Wish birthday to :%@",[kAppDelegate.commString objectAtIndex:indexPath.row];

    NSString *date =[kAppDelegate.String objectAtIndex:indexPath.row];

    NSDate *dateP = [ dateformat dateFromString:date];
    components = [[NSCalendar currentCalendar] components:NSCalendarUnitDay | NSCalendarUnitMonth | NSCalendarUnitYear fromDate:dateP];
        [components setHour:4];
        [components setMinute:59];
        [components setSecond:10];

    reminderNote.fireDate = [[NSCalendar currentCalendar] dateFromComponents:components];
    }

其中单元格是 UITableviewCell 的对象，但没有任何类型的通知。我知道有一个小Bug，请帮我找出来。

Answer 1

• 将最后一行作为 [[UIApplication sharedApplication] scheduleLocalNotification:reminderNote]; 放在 reminderNote.fireDate 行之后。

• 记录 reminderNote.fireDate 并检查格式。

希望这对您有所帮助。
