Question

I want to add a UIWebView into a cell. THe HTML data will change and I will call reloadData when this happens.

Problem is, the UIWebView changes nicely but I can’t get the UITableViewCell to match the height properly. I’ve tried and failed at this solution…

When webview loads:

- (void)webViewDidFinishLoad:(UIWebView *)aWebView {
    CGRect frame = aWebView.frame;
    int old_height = frame.size.height;
    frame.size = CGSizeMake(280, 0);
    aWebView.frame = frame;
    float content_height = [[aWebView stringByEvaluatingJavaScriptFromString:@"document.body.offsetHeight;"] floatValue];
    frame = aWebView.frame;
    frame.size = CGSizeMake(280, content_height + 20);
    aWebView.frame = frame;
    NSLog(@"SIZES - %i - %i",old_height + 4,(int) frame.size.height);
    if(old_height + 4 != frame.size.height){
        [self.tableView reloadData];
    }
}

Returned height for cell:

return webview.frame.size.height + 20;

After the first load the cell is not sized properly. It’s hard to figure out how to do this. I need to stretch the entire content downwards to fit a cell.

Thank you.

UIWebView isn’t designed to work inside another scroller (like UITableView);

And to resize the cell you should use either UITableView.rowHeight property or the following UITableViewDelegate method :

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath

And by the way, [UITableView reloadData] is normally a bad decision for updating the table.
