    <p>I have a <code>UIViewController</code> with a custom background color. On top of it there's a <code>UITableView</code> with <code>UITableViewCells</code> that are semi-transparent (white color with opacity 0.5).</p> <p>The issue I'm blaming about and the one I'm banging my head against the wall is in iOS 7, when you have a <code>UITableViewCell</code> with semi-transparent background and you try to delete/insert/moving rows (so relying on an animation effect) the entire <code>UITableView</code> with its cells <strong><em>flashing</em></strong> for just 0.1 second and set cells background to a more transparent one. This is very annoying.</p> <p>The only thing I'm doing is set the background color of <code>self.view</code> with:</p> <pre><code>self.view.backgroundColor = [UIColor colorWithRed:0.4 green:0.5 blue:0.7 alpha:1]; </code></pre> <p>and set the background color of cells with:</p> <pre><code>- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath { cell.backgroundColor = [UIColor colorWithWhite:1 alpha:0.5]; } </code></pre> <p>Here's a gif showing you the problem: </p> <p><img src="https://i.stack.imgur.com/L5c8S.gif" alt="enter image description here"></p> <p>And here's the super simple project: <a href="https://github.com/socksz/TransparentCellFlashing" rel="nofollow noreferrer">https://github.com/socksz/TransparentCellFlashing</a></p> <p>Please help me to solve this ridicolous issue! :P</p>

    1. COWhat is the background colour of your UITableView? If you have set one, try setting it to "clear" (or any colour of your choice) in your xib/storyboard. Normally in iOS7, it is set to "default", which is the cause for most of these issues.

    2. COIt seems that it doesn't matter. I've tried to set the background color of `self.view` (which is the table view) to `[UIColor clearColor]` and also tried to embed the table view in a `UIView` (the main view of the view controller) and set the background color of this view to clear. Doesn't work.

    3. COOh OK. Then you probably need to override setSelected() property of your UITableViewCell by subclassing it. Or at least use the backgroundView property instead of the backgroundColor.

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.
