    <p>Declare the method like this in your <code>@interface</code>:</p> <pre><code>- (id)myObjectWithObjects:(id)firstObject, ... NS_REQUIRES_NIL_TERMINATION; </code></pre> <p>Then in the <code>@implementation</code> you would define it like this:</p> <pre><code>- (id)myObjectWithObjects:(id)firstObject, ... { va_list args; va_start(args, firstObject); for (id arg = firstObject; arg != nil; arg = va_arg(args, id)) { // Do something with the args here } va_end(args); // Do more stuff here... } </code></pre> <p>The <code>va_list</code>, <code>va_start</code>, <code>va_arg</code> and <code>va_end</code> are all standard C syntax for handling variable arguments. To describe them simply:</p> <ul> <li><code>va_list</code> - A pointer to a list of variable arguments.</li> <li><code>va_start</code> - Initializes a va_list to point to the first argument after the argument specified.</li> <li><code>va_arg</code> - Fetches the next argument out of the list. You must specify the type of the argument (so that va_arg knows how many bytes to extract).</li> <li><code>va_end</code> - Releases any memory held by the va_list data structure.</li> </ul> <p>Check out this article for a better explanation - <a href="http://cocoawithlove.com/2009/05/variable-argument-lists-in-cocoa.html" rel="noreferrer">Variable argument lists in Cocoa</a></p> <hr> <p>See also: <a href="http://pubs.opengroup.org/onlinepubs/009695399/basedefs/stdarg.h.html" rel="noreferrer">"IEEE Std 1003.1 stdarg.h"</a></p> <hr> <p>Another example from the <a href="http://developer.apple.com/library/mac/#qa/qa1405/_index.html" rel="noreferrer">Apple Technical Q&amp;A QA1405 - Variable arguments in Objective-C methods</a>:</p> <pre><code>@interface NSMutableArray (variadicMethodExample) - (void) appendObjects:(id) firstObject, ...; // This method takes a nil-terminated list of objects. @end @implementation NSMutableArray (variadicMethodExample) - (void) appendObjects:(id) firstObject, ... { id eachObject; va_list argumentList; if (firstObject) // The first argument isn't part of the varargs list, { // so we'll handle it separately. [self addObject: firstObject]; va_start(argumentList, firstObject); // Start scanning for arguments after firstObject. while (eachObject = va_arg(argumentList, id)) // As many times as we can get an argument of type "id" [self addObject: eachObject]; // that isn't nil, add it to self's contents. va_end(argumentList); } } @end </code></pre>

    1. COThanks, ACCEPTED. Just adding that I found http://cocoawithlove.com/2009/05/variable-argument-lists-in-cocoa.html, and it'd be nice if you edited your answer telling readers that stdarg use is needed. Anyways, huge thanks, will accept as soon as StackOverflow allows me to.

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.
