    <p>I'm doing an iPhone application which uses a navigation control to browse through some data. This data is stored in a sqlite database and I have a class which gets it and returns it in a NSMutableArray of NSStrings.</p> <p>The problem is that in the first screen of the navigation everything works prefectly, but in the second screen (another view which is pushed) the same code fails because the NSMutableArray gets corrupted. In the debugger I can see that it is returned correctly, but when it's time to use it the pointers have become corrupted and the application crashes.</p> <p>I have put breakpoints in all my functions, and I can't see anywhere where it can get corrupted. And as the first view, which uses the same exact code, even accesing the same eact tables, works correctly I don't really know where to look.</p> <p>If anyone want to have a look at the code I have uploaded it to my site: <a href="http://sachafuentes.com/iBacus.zip" rel="nofollow noreferrer" title="http://sachafuentes.com/iBacus.zip">http://sachafuentes.com/iBacus.zip</a></p> <p>Thanks in advance.</p> <p>UPDATE:</p> <p>The problem lies in the function where I get the data, which looks like (this is a simplified version with some pseudo-code).</p> <pre><code>-(NSMutableArray *) getPaises { NSMutableArray * paises; paises = [[NSMutableArray alloc] init]; while( get new row ) { NSString *aPais = get the value; [paises addObject:aPais]; [aPais release]; } return paises; } </code></pre> <p>If I comment out [aPais release] everything works, but to me this looks like a memory leak, as the NSString won't be released.</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.
