    <p>I inherited an old iPhone app that I'm converting from NIBs to a storyboard. One thing that I can't seem to figure out is that the first page of cells in a UITableView is covered by the background color. I've verified that the cells are being created and being filled out. But I just can't see them. Once I scroll down, the lower cells look fine.</p> <p>TableView code:</p> <pre><code>- (CGFloat) tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section { return segment_SECTION_HEIGHT; } - (CGFloat) tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath { return segment_CELL_HEIGHT; } - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { NSArray * allKeys = [segmentsByTimeDictionary allKeys]; return allKeys.count; } - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { NSString *date = [timeSections objectAtIndex: section]; NSMutableArray *timesegments = [segmentsByTimeDictionary objectForKey: date]; return timesegments.count; } - (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section { NSString *date = [timeSections objectAtIndex: section]; UIView *headerView = [[GradientView alloc] initWithStartColor: segment_SECTION_COLOR_TOP endColor: segment_SECTION_COLOR_BOTTOM]; headerView.frame = CGRectMake(0, 0, tableView.frame.size.width, segment_SECTION_HEIGHT); UILabel *timeLabel = [[UILabel alloc] initWithFrame: CGRectMake(10, 0, 320, segment_SECTION_HEIGHT)]; timeLabel.backgroundColor = [UIColor clearColor]; timeLabel.font = [UIFont boldSystemFontOfSize: 16]; timeLabel.text = date; timeLabel.textColor = segment_SECTION_TEXT_COLOR; [headerView addSubview: timeLabel]; return headerView; // return date; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"segmentCell"; segmentCell *cell = [tableView dequeueReusableCellWithIdentifier: CellIdentifier]; NSDate *date = [timeSections objectAtIndex: indexPath.section]; NSMutableArray *timesegments = [segmentsByTimeDictionary objectForKey: date]; segments *segment = [timesegments objectAtIndex: indexPath.row]; [cell setName: segment.name]; return cell; } </code></pre> <p>Edited to add: I noticed if I remove this function call from viewDidLoad, then it goes away:</p> <pre><code>drawGradientBackground(self.view, DEFAULT_BACKGROUND_TOP, DEFAULT_BACKGROUND_BOTTOM); </code></pre> <p>That function is defined as </p> <pre><code>CAGradientLayer *gradient = [CAGradientLayer layer]; gradient.colors = [NSArray arrayWithObjects: (id) startColor.CGColor, (id) endColor.CGColor, nil]; gradient.frame = view.layer.bounds; [view.layer insertSublayer: gradient atIndex: 0]; </code></pre> <p>Screenshot: <img src="https://i.stack.imgur.com/cc0m7.png" alt="UITableView Screenshot"></p>

    1. COAfter you scroll down and see cells, then scroll back up, what do you see there? Could you please show how you have set up your storyboard?

    2. COAfter I scroll down and scroll back up, the cells are still covered up. I'm still thinking it has something to do with the gradient.

    3. COLet's try something. Set the `clipsToBounds` of the gradient view to `YES` and see if it helps.

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.
