    <p>i have a huge huge problem, i feel like i will never get rid of it. i got a xml file coming from my server, parsing it well. but i got duplicates in that xml file. The thing is i need to get rid of the duplicates in my NSMutableArray, in order to know what i have in my NSMutable array and display a little menu with wich section is avaible and wich is not. But i can't manage to copy only the good stuff into another array since the NSMutableArray is as a matter of fact a Array of dictionaries. And i don't know how to manage them, i tried sevral things the past two days with no results, so please if someone can help me it would very appreciated. </p> <p>here is my entire code (hope it doesn't burn you eyes :3) :</p> <pre><code>#include &lt;CommonCrypto/CommonDigest.h&gt;

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.
