    <p>I have an action sheet with options that vary depending on the circumstances. There are enough different button titles that I would like to construct an array of those button titles first, but I can't figure out how to convert that into the varargs format. </p> <p>I want to do something like this:</p> <pre><code>NSMutableArray *buttonTitles = [NSMutableArray array]; if (condition1) { [buttonTitles addObject: @"Do action 1"]; } if (condition2) { [buttonTitles addObject: @"Do action 2"]; } if (condition3) { [buttonTitles addObject: @"Do action 3"]; } if (condition4) { [buttonTitles addObject: @"Do action 4"]; } UIActionSheet *actionSheet = [[[UIActionSheet alloc] initWithTitle: nil delegate: self cancelButtonTitle: @"Cancel" destructiveButtonTitle: nil otherButtonTitles: buttonTitles] autorelease]; </code></pre> <p>Now obviously if I had to I could do something like this instead:</p> <pre><code>UIActionSheet *actionSheet = nil; if (condition1 &amp;&amp; condition2 &amp;&amp; condition3 &amp;&amp; condition4) { actionSheet = [[[UIActionSheet alloc] initWithTitle: nil delegate: self cancelButtonTitle: @"Cancel" destructiveButtonTitle: nil otherButtonTitles: @"Do action1", @"Do action2", @"Do action3", @"Do action 4", nil] autorelease]; } else if (condition1 &amp;&amp; condition2 &amp;&amp; condition3 &amp;&amp; !condition4) { actionSheet = [[[UIActionSheet alloc] initWithTitle: nil delegate: self cancelButtonTitle: @"Cancel" destructiveButtonTitle: nil otherButtonTitles: @"Do action1", @"Do action2", @"Do action3", nil] autorelease]; } // else ... // about 14 other cases! </code></pre> <p>But that would be horrible. Anyone know some nice syntactic sugar to help me out?</p> <p><b>EDIT:</b> It has been suggested that I use <code>addButtonWithTitle</code>, which on the face of it looks great, unfortunately it this puts the additional buttons after the cancel button, which isn't desirable. </p> <p>I believe this is bug with Apple's code since their documentation on <code>addButtonWithTitle</code> states: </p> <pre><code>// adds a button with the title. returns the index (0 based) of where it was added. buttons are displayed in the order added except for the // destructive and cancel button which will be positioned based on HI requirements. buttons cannot be customized. </code></pre> <p>HI requirements (Apple's own Human Interface guidelines) favor the cancel button below all other options, so I'd say Apple screwed up. Of course, that doesn't really help me, so I'm back to trying to convert between an NSArray and a varargs, which I still don't know how to do.</p>

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.
