Body
<p>I'm trying to make an image 100% the height of the cell, but it doesn't seem to update correctly.</p> <p>I have created a special <code>getCellHeightFromData</code> method that is meant to calculate the height from the text length. I also have a method called <code>getRestaurantPictureById</code> that downloads an image from a web server which responds with an image resized to the specific width and height, and returns it as an <code>UIImage</code>.</p> <p>I want to set the <code>UIImageView</code> to the same width and height as the image that was loaded. I have access to both the width and height as float numbers, so that is not the problem.</p> <h3>The UIImageView outlet looks like this</h3> <pre><code>@property (weak, nonatomic) IBOutlet UIImageView *Thumbnail; </code></pre> <h3>My attempt at resizing the image (from inside my UITableViewCell subclass)</h3> <pre><code>- (void)updateCellWithContent:(RestaurantCell*)restaurant { self.NameLabel.text = [restaurant name]; float width = 75.0; float height = [RestaurantCell getCellHeightFromData:restaurant]; self.Thumbnail.frame = CGRectMake(self.Thumbnail.frame.origin.x, self.Thumbnail.frame.origin.y, width, height); self.Thumbnail.image = [DataLoader getRestaurantPictureById:restaurant.restaurantId withWidth:width andHeight:height]; } </code></pre> <p>It does not look correctly immediately when I run, but if I scroll so that a cell goes out of sight, and then let it bounce back, it has been redrawn with the proper (100%) height.</p> <h3>Before scrolling out of sight</h3> <p><img src="https://i.stack.imgur.com/x8vHP.png" alt="Before"></p> <h3>After scrolling the first cell out of sight and letting it bounce back</h3> <p><img src="https://i.stack.imgur.com/lOPAd.png" alt="enter image description here"></p> <p><strong>Any ideas? Thanks in advance :)</strong></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.
