    <p>Here is how I implemented this in case anyone else is trying to do this (I have limited it to 2-button combos but I could easily extend the logic to 3 &amp; 4-button combos as well). I chose to handle each touch individually using the ccTouchBegan/Ended/Moved instead of using the ccTouchesBegan/Ended/Moved because I just couldn't get it to work with the hash code. Any alternative ideas would be welcome.</p> <p>spuButton.h (a CCSprite Subclass)</p> <pre><code>#import &lt;Foundation/Foundation.h&gt; #import "cocos2d.h" typedef enum tagButtonState { kButtonStatePressed, kButtonStateNotPressed } ButtonState;

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.
