我在每个部分有四个部分，有五行。当点击任何一行时，它会再次点击时显示实际数据，它会显示另一个部分数据。我无法理解我错在哪里。重复数据在另一行中。这是我的代码和图片。

if (section==0) {

我不知道，你在为此尝试什么...但尝试跟随，我希望它可以帮到你：

假设您显示日期和标题：

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath (NSIndexPath *)indexPath{
        if (indexPath.section == 0){
            NSPredicate *predicate = [NSPredicate predicateWithFormat:@"Category =[cd] %@", @"Category 1"];
            NSArray * catArray = [self.notes filteredArrayUsingPredicate:predicate];
            cell.textLabel.text = [[catArray objectAtIndex:indexPath.row] objectForKey:@"Title"];
            cell.detailTextLabel.text = [[catArray objectAtIndex:indexPath.row] objectForKey:@"Date"];

        } else if (indexPath.section == 1){
            NSPredicate *predicate = [NSPredicate predicateWithFormat:@"Category =[cd] %@", @"Category 1"];
            NSArray * catArray = [self.notes filteredArrayUsingPredicate:predicate];
            cell.textLabel.text = [[catArray objectAtIndex:indexPath.row] objectForKey:@"Title"];
            cell.detailTextLabel.text = [[catArray objectAtIndex:indexPath.row] objectForKey:@"Date"];
        } 
    }

这样做。
