    <p>My table view cell has four labels. The table view is not smooth when scroll in first time. After all cells displayed one time, the scrolling is so smooth with no problem. So I thought the problem is the speed of loading one cell in the first time.</p> <p>I have reuse cell but the problem is not solved. Please help me! Thanks so much!</p> <p>Here is my code:</p> <pre><code>// Customize the appearance of table view cells. - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *MyIdentifier = @"MyIdentifier"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:MyIdentifier]; if (cell == nil) { NSArray *views = [[NSBundle mainBundle] loadNibNamed:@"ForumListTableViewCell" owner:self options:nil]; cell = [views objectAtIndex:0]; } NSDictionary *cate = [_forums objectAtIndex:indexPath.section]; NSArray *forumsInCate = [cate objectForKey:@"forums"]; NSDictionary *forumInfo = [forumsInCate objectAtIndex:indexPath.row]; // title1 UILabel *forumTitleLabel = (UILabel *)[cell viewWithTag:1]; forumTitleLabel.text = [forumInfo objectForKey:@"name"]; // master UILabel *masterLabel = (UILabel *)[cell viewWithTag:2]; NSString *master = [forumInfo objectForKey:@"moderators"]; masterLabel.text = master; // title2 UILabel *threadTitleLabel = (UILabel *)[cell viewWithTag:3]; NSString *lastPostTitle; NSDictionary *lastPostInfo = [forumInfo objectForKey:@"lastpost"]; lastPostTitle = [lastPostInfo objectForKey:@"subject"]; threadTitleLabel.text = lastPostTitle; // author UILabel *authorLabel = (UILabel *)[cell viewWithTag:4]; authorLabel.text = [NSString stringWithFormat:@"%@ / %@", [forumInfo objectForKey:@"threads"], [forumInfo objectForKey:@"posts"] ]; return cell; } </code></pre>

    1. COyou dont seem to init/alloc your variables. dont think its related though. I would try on the simulator and device to see if this is reproducible.

    2. COI have inited all the vars in another function, so i think it may be not the reason. I have tested it in simulator and it worked very well. It's very smooth in simulator, but not smooth in iPhone.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
