IOS 11表确实选择了问题

Question

我正在使用table将数组中的值设置为行中的标签。 在ios 10中，当我选择表行时，它可以工作，但在ios 11中，当我选择一行时，单元格标签值仅替换为Label文本。 任何人都可以帮忙。 这是我所做的代码：=

-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
    return arrpickuprequest.count;
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
            cell.lblName.text = [[arrpickuprequest objectAtIndex:indexPath.row-1]valueForKey:@"Name"];
          cell.btncheck.tag = indexPath.row;

        if([[arrpickuprequestChecked objectAtIndex:indexPath.row] isEqualToString:@"Uncheck"])
            [cell.btncheck setImage:[UIImage imageNamed:@"uncheck"] forState:UIControlStateNormal];
        else
            [cell.btncheck setImage:[UIImage imageNamed:@"check"] forState:UIControlStateNormal];

        [cell.btncheck addTarget:self action:@selector(purchase_click:) forControlEvents:UIControlEventTouchUpInside];
        cell.selectionStyle = UITableViewCellSelectionStyleNone;
        return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {

        if (indexPath.row==0) {
            if([[arrpickuprequestChecked objectAtIndex:indexPath.row] isEqualToString:@"Uncheck"])
                                {
                                    for (int i=0; i<[arrpickuprequest count]+1; i++) {
                                        [arrpickuprequestChecked replaceObjectAtIndex:i withObject:@"Check"];
                                    }
                                }
                                else
                                {
                                    for (int i=0; i<[arrpickuprequest count]+1; i++) {
                                        [arrpickuprequestChecked replaceObjectAtIndex:i withObject:@"Uncheck"];

                                    }
                                }
        }
        else {
            if([[arrpickuprequestChecked objectAtIndex:indexPath.row] isEqualToString:@"Uncheck"])
                {
                    [arrpickuprequestChecked replaceObjectAtIndex:indexPath.row withObject:@"Check"];
                }
                else
                {
                    [arrpickuprequestChecked replaceObjectAtIndex:indexPath.row withObject:@"Uncheck"];
                    [arrpickuprequestChecked replaceObjectAtIndex:0 withObject:@"Uncheck"];
                }
            }
            [tblPickupreuest reloadData];
}
