    <p>This line is garbage:</p> <pre><code>[request setDidFinishSelector:[self performSelector:@selector(imageDownloaded:idPlace:)withObject:request withObject:place.idPlace]]; </code></pre> <p>This should be throwing a compiler warning at the very least. You're executing <code>-imageDownloaded:idPlace:</code> immediately, and then taking the result (which in your case is going to be whatever garbage value was on the stack) and returning that as the selector. the response data is nil because you're actually executing your <code>imageDownloaded:</code> method before the request even runs.</p> <p>Assuming ASIHTTPRequest only accepts didFinishSelectors of the form <code>foo:</code> (e.g. one argument), then there's no good way to do what you're trying to do, which is to attach a second argument onto the method. That simply won't work. You have a few alternatives, but the simplest one is probably to make use of ObjC Associated Objects. You can hang your <code>place.idPlace</code> object off of the request and get at it later.</p> <p>At the top of your file, define a key:</p> <pre><code>static char kAssociationKey; // we just want its memory location </code></pre> <p>Then when you start the request you can run:</p> <pre><code>objc_setAssociatedObject(request, &amp;kAssociationKey, place.idPlace, OBJC_ASSOCIATION_RETAIN_NONATOMIC); [request setDidFinishSelector:@selector(imageDownloaded:)]; </code></pre> <p>This will attach <code>place.idPlace</code> to the request object. Then in your didFinishSelector you can run</p> <pre><code>id oldIdPlace = objc_getAssociatedObject(request, &amp;kAssociationKey); </code></pre>

    1. COfinally i override the ASIHTTPRequest in order to add a property with the idPlace. But also i tried your answer and it works. So thanks you very much

    2. COI suppose you could also just subclass ASIHTTPRequest to add your own property.

    3. COASIHTTPRequest has a userInfo dictionary property you can attach stuff to. You don't need to actually use associated objects or subclass.

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.
