    <p>I'm making an app which will fetch pictures resources and text from web service. I pick the great AFNetworking's UIImageView+AFNetworking category to deal with the image downloading stuff.</p> <p>However, I'm facing a memory problem. I used <strong>Allocation</strong> tool of the <strong>Instruments</strong>, finding each time I load more images, there will always be a growth of memory allocation, 1-2 MB in size. I tracked down to the source code, it turned out that it lies in AFNetworking's code.</p> <p>The exact line of code is:</p> <pre><code>- (void)connectionDidFinishLoading:(NSURLConnection *)__unused connection { self.responseData = [self.outputStream propertyForKey:NSStreamDataWrittenToMemoryStreamKey]; [self.outputStream close]; [self finish]; self.connection = nil; } </code></pre> <p>This will occupy 99.6% of the memory allocation.</p> <p>I user ARC in the project, display the UIImageViews in a UITableView and configure the cell like the following code:</p> <pre><code>[self.imageView setImageWithURLRequest:request placeholderImage:nil success:successBlock failure:failBlock]; </code></pre> <p>Can any one offer some idea about the memory issue? It's really a headache cuz once the memory is allocated, they will never be cleared even if I cleared the whole image view. After a little while, my app will occupy more than 100MB from the <strong>Real Memory Usage</strong> window of <strong>Instruments</strong>.</p> <p>Any help will be greatly appreciated!! Thanks in advance!!</p>

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.
