Question

我有一个tableview，需要三个textview进行描述。我制作了一个包含带有标签1000的文本视图的原型单元格。我想重复使用这个textview，但是当我滚动时，textview的文本会发生变化。

有一段时间法拉兹采取haider textview的位置，有时zaidi采取faraz的位置。

我尝试给他们独特的标签，但它仍然没有帮助我。

NSString *cellViewIdentifier = nil;
long section = indexPath.section;
UITableViewCell *cell;

if(section == kSocialStatusSection) {

        cellViewIdentifier = kCheckBoxItemCellViewIdentifier;
        cellViewIdentifier = [cellViewIdentifier stringByAppendingString:langAppendString];
        cell = (UITableViewCell *)[tableView dequeueReusableCellWithIdentifier:cellViewIdentifier];
        [cell setBackgroundColor:[UIColor clearColor]];

        SocialStatus *  socialStatus = [socialResult.socialStatus objectAtIndex:indexPath.row];

                    [cell setBackgroundColor:[UIColor clearColor]];

我们可以使用包含每个单元格的字符串的NSMutableArray对象。您必须使用空字符串填充数组并使用此信息填充文本字段。它会像，

 textView.text = [textViewStringsArr objectAtIndex:indexPath.row];

由于您在视图控制器中以编程方式执行此操作，因此您必须将视图控制器设置为文本视图委托。你可以做到

-(void)textViewDidEndEditing:(UITextView *)textView {
UITableViewCell *cell = (UITableViewCell*)textField.superview;

NSIndexPath *indexPath = [self.tableView indexPathForCell:cell];

... Since you've the index path, you can map it to an array.

[textViewStringsArr replaceObjectAtIndexPath:indexPath withObject:textView.text];
}

这将是基本的想法。从可变数组的空字符串开始，每次更新文本视图时通过用新文本替换原始文本来修改它们。希望这会有所帮助。
