Question

UITableView only shows data from JSON array when I scroll up and down. When I load the table view it shows cells but they are blank and as I scroll up and down it then starts showing the data.

How do I show the cells with data without scrolling?

- (void)requestFinished:(ASIHTTPRequest *)request
{    
    if (request.responseStatusCode == 400) {
        NSLog( @"Code already used");

    } else if (request.responseStatusCode == 403) {
        NSLog( @"Code already used");

    } else if (request.responseStatusCode == 200) {
        NSLog(@"%@",[request responseString]);
        NSString *response = [request responseString];
        const char *convert = [response UTF8String];
        NSString *responseString = [NSString stringWithUTF8String:convert];
        responseArray  = [responseString JSONValue];
        Nrows = [responseArray count];

    }
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"Cell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

    if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] autorelease];
    }

    NSDictionary *dict = [responseArray objectAtIndex:indexPath.row];
    cell.detailTextLabel.text = [dict objectForKey:@"allfeeds"];
    cell.textLabel.adjustsFontSizeToFitWidth = YES;
    cell.textLabel.font = [UIFont systemFontOfSize:12];
    cell.textLabel.minimumFontSize = 10;
    cell.textLabel.numberOfLines = 4;
    cell.textLabel.lineBreakMode = UILineBreakModeWordWrap;
    cell.textLabel.text = [dict objectForKey:@"allfeeds2"];
    cell.selectionStyle = UITableViewCellSelectionStyleNone;

    return cell;
}

Instead of starting the request asynchronously (non-blocking)

[request startAsynchronously];

Try doing it synchronously (blocking)

[request startSynchronously];
