我有自定义单元格的表视图。在我的自定义单元格中,我有一个标签和textView,我想从textView获取数据以保存在feedBack按钮中。当我在我的数据数组中添加txtView时,我得到两次自定义单元格。如何删除此问题

- (void)textViewDidEndEditing:(UITextView *)textView
{
    FeedbackQuestionDC *feedBack = [dataArray objectAtIndex:textView.tag];
    feedBack.FeedbackQuestionDC_Answers=textView.text;
    [dataArray addObject:feedBack];
    [myTableView reloadData];


}


- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

    static NSString *simpleTableIdentifier = @"Feed Back";

    feedBackCC *cell = (feedBackCC *)[tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
    if (cell == nil) {
        UIViewController *c = [[UIViewController alloc] initWithNibName:@"feedBackCC" bundle:nil];
        cell = (feedBackCC *) c.view;

    }
    cell.textLabel.font = [UIFont boldSystemFontOfSize:15.0];
    FeedbackQuestionDC *feedBack = [dataArray objectAtIndex:[indexPath row]];
         cell.lblQuestion.text = feedBack.FeedbackQuestionDC_QuestionText;

    cell.txtViewAnswer.tag=indexPath.row;
    cell.txtViewAnswer.text=feedBack.FeedbackQuestionDC_Answers;

    cell.txtViewAnswer.delegate=self;



    return cell;

}

首先获取特定索引处的单元格,然后从中获取视图,然后查看textview

使用以下功能获取单元格

[table cellForRowAtIndexPath:[NSIndexPath indexPathForRow:0 inSection:0]]

//我认为这对你有用,试试这个

- (void)textViewDidEndEditing:(UITextView *)textView
{
    feedBackCC *cellsuperView = (feedBackCC *)[textView superview];

    nslog(@"%@",cellsuperView.txtViewAnswer.text);
}

答案 2 :(得分:2)

- (void)textViewDidEndEditing:(UITextView *)textView
{
   FeedbackQuestionDC *feedBack = [dataArray objectAtIndex:textView.tag];
   feedBack.FeedbackQuestionDC_Answers=textView.text;
   [dataArray addObject:feedBack]; //REMOVE THIS LINE 
   [myTableView reloadData];
}

请参阅上面的代码删除我建议的行,您不需要再次将对象添加到数组中,它已经使用dataArray中对象的引用进行了更新。

希望这会有所帮助..
