    text
    <p>I have created a cell using</p> <pre><code>static NSString *CellIdentifier = @"TweetListUserName"; CustomTableViewCell *cell = (CustomTableViewCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[CustomTableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier]autorelease] ; } </code></pre> <p>and used the following code to set up a section header: </p> <pre><code>- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section { UIView* customView = [[[UIView alloc] initWithFrame:CGRectMake(0.0, -4.0, 320.0, 67.0)]autorelease]; [customView setOpaque:YES]; UIImageView *image = [[UIImageView alloc] initWithFrame:CGRectMake(-2.0, -4.0, 328.0, 67.0)]; [image setImage:[UIImage imageNamed:@"header-msg.png"]]; [image setOpaque:YES]; [customView addSubview:image]; UILabel *label1 =[[UILabel alloc] initWithFrame:CGRectMake(10, 5, 100, 12)]; label1.text =@"TWEETS MATCHING:"; label1.textAlignment=UITextAlignmentLeft; [label1 setTextColor:[UIColor grayColor]]; [label1 setFont:[UIFont fontWithName:@"Helvetica" size:9]];; [label1 setBackgroundColor:[UIColor clearColor]]; [customView addSubview:label1]; [label1 release]; UILabel *label2 =[[UILabel alloc] initWithFrame:CGRectMake(10, 6, 315, 50)]; label2.text =usernametag; label2.textAlignment=UITextAlignmentLeft; [label2 setTextColor:[UIColor blackColor]]; [label2 setFont:[UIFont fontWithName:@"Helvetica-Bold" size:20]]; [label2 setBackgroundColor:[UIColor clearColor]]; [customView addSubview:label2]; [label2 release]; return customView; } </code></pre> <p>However, when I quickly scroll the table the header flickers in almost all cases. How can I prevent this flickering?</p>

Guidance
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.
