Body
<p>I need to create an object in one class hierarchy that wraps an object from a different one. They both have very similar interfaces, and I'd like to automatically have my wrapper forward messages it doesn't recognize to its target in lieu of implementing its own properties. I got this to work using something like this:</p> <pre> - (id)forwardingTargetForSelector:(SEL)sel { if ([self.wrappedObject respondsToSelector:sel]) return self.wrappedObject; return self; } </pre> <p>But this doesn't work for key-value coding. How can I go about having my wrapper implement key-value coding in a way that uses the properties of its wrapped object?</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.
