    <p>I have the following code to download an image:</p> <pre><code> imageRequest = [ASIHTTPRequest requestWithURL:[NSURL URLWithString:magazineItem.contentURL]]; __weak ASIHTTPRequest *weakRequest = imageRequest; __block typeof (self) bself = self; [imageRequest setCompletionBlock:^{ if (weakRequest.responseStatusCode == 200) { bself.imageData = weakRequest.responseData; [[DataAccessLayer sharedInstance] storeTemporaryContentData:bself.imageData url:magazineItem.contentURL]; bself.contentImage = [UIImage imageWithData:bself.imageData]; if (bself.contentImage != nil) { if (bself.magazineItem.presentationStyle.intValue != -1) { [bself setPresentationStyle:bself.magazineItem.presentationStyle.intValue]; } else { [bself setPresentationStyleForImage:bself.contentImage]; } } else [bself.delegate contentItemViewUnavailable:bself]; } else { [bself.delegate contentItemViewUnavailable:bself]; } }]; [imageRequest setFailedBlock:^{ if (weakRequest.error.code == 4) return; [bself.delegate contentItemViewUnavailable:bself]; }]; [imageRequest startAsynchronous]; </code></pre> <p>And though I'm using a <code>__block typeof (self)</code> identifier to pass the self into the block, it still gets retained. I also have tried <code>__weak MyClassName *bself = self;</code> and it still gets into retain cycle. It seem I'm missing something here, can anyone fill me up with what exactly am I doing wrong?</p> <p>For reference <code>imageRequest</code> is a __strong iVar in my .m file category.</p> <p>Thanks in advance.</p>

    1. COdid you set imageRequest strong? @propert(nonatomic,strong) ASIHTTPRequest *imageRequest;

    2. COYes, the iVar is strong by default, but I'm using another request as a weak reference to the strong one, keeping it in memory for further operations like cancel.

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
