在iOS中按UITableView的单元格时如何打开展开的视图？

Question

I have UIWebView. I want to open it just under the UITableView. I have custom cell, with button, or even it can be expand of click of cell (didselectrow).

How can I put UIWebView under Cell and expand it when cell is clicked.

I want also to close it when another cell is clicked, as it will open its respective webview.

Thanks

This is an outline of how you can achieve this. The code is not tested, but should be pretty self-explanatory. Let me know if you have questions about it.

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    _selectedCellIndexPath = indexPath;

    // redraw the visible cells, which will now expand the selected cell
    [_tableView reloadData];
}


- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{ 
    if([indexPath compare: _selectedCellIndexPath] == NSOrderedSame) {
        return EXPANDED_CELL_HEIGHT;
    } 
    else {
        return NORMAL_CELL_HEIGHT;
    }
}


- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
     MyCell *cell = …. // get the cell
    if([indexPath compare: _selectedCellIndexPath] == NSOrderedSame) {
        return cell.webView.hidden = NO;
        // update the web view if necessary
    } 
    else {
        return cell.webView.hidden = YES;
    }


    return cell;
}

this should help you, you need to add web view to your custom cells and update the row height:
