    <p>I am building my first iPhone/Obj-c app and I have a large amount of data-holding subclasses that I am passing into a cite function. To the cite function these objects are anonymous and I need to find a way to access all the variables of each passed object. I have been using a pre-built NSArray and Selectors to do this but with more than 30 entries (and growing) it is kind of silly to do manually. There has to be a way to dynamically look up all the variables of an anonymous object.</p> <p>The <a href="http://developer.apple.com/iphone/library/documentation/Cocoa/Reference/ObjCRuntimeRef/Reference/reference.html" rel="nofollow noreferrer">obj-c runtime</a> run-time docs mention this problem but from what I can tell this is not available in iPhone OS. If it is then I don't understand the implementation and need some guidance. <a href="https://stackoverflow.com/questions/754824/get-an-object-attributes-list-in-objective-c">A similar question</a> was asked before but again I think they were talking about OSX and not iPhone.</p> <p>Any thoughts?</p> <pre><code>-(NSString*)cite:(id)source { NSString *sourceClass = NSStringFromClass([source class]); // Runs through all the variables in the manually built methodList for(id method in methodList) { SEL x = NSSelectorFromString(method); // further implementation // Should be something like NSArray *methodList = [[NSArray alloc] initWithObjects:[source getVariableList]] for(id method in methodList) { SEL x = NSSelectorFromString(method); // Further implementation } </code></pre>

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.
