    <p>I will become crazy with this bug ! I have this piece of code which works well on iOS 4.3</p> <pre><code>newRegistered.ticket_id = [NSNumber numberWithInt: [curRegistered objectForKey:@"ticket_id"] intValue]]; </code></pre> <p>If I do :</p> <pre><code>NSLog(@"ID before : %d, ID after : %d", [curRegistered objectForKey:@"ticket_id"] intValue], [newRegistered.ticket_id intValue]); </code></pre> <p>I Have on iOS 4.3 :</p> <blockquote> <p>ID before : 35459, ID after : 35459</p> </blockquote> <p>And on iOS 5.0 :</p> <blockquote> <p>ID before : 35459, ID after : -30077</p> </blockquote> <p>Please help ! Thank you for advance.</p> <p><strong>##EDIT :##</strong> I have investigated a bit more the problem. It seems the problem comes from assigning a NSNumber in CoreData. I should have specified that the piece of code above is used with CoreData (newRegistered is a NSManagedObject, and curRegistered is a NSDictionary containing JSON Data (only strings, never int or long...)).</p> <p>Here is the specific problem :</p> <pre><code>long long test = 789654; Registereds *a = [NSEntityDescription insertNewObjectForEntityForName:@"Registereds" inManagedObjectContext:self.managedObjectContext]; a.ticket_id = [NSNumber numberWithLongLong:test]; NSLog(@"%lld -&gt; %@", test, a.ticket_id); // Displays 789654 -&gt; 3222 on iOS 5 and 789654 -&gt; 789654 on iOS 4.3 NSNumber *ticket_id = [NSNumber numberWithLongLong:test]; NSLog(@"%lld -&gt; %@", test, ticket_id); // Displays 789654 -&gt; 789654 </code></pre> <p>So it seems the problem comes from the Registereds object (which is a NSManagedObject, like the newRegistered in the previous example). </p> <p>Do you have any idea why this happens? I have never seen something like that in more than 2 years of coding, this bug really makes me think I don't know how to code...</p>

    1. COYou could try to use `[NSNumber numberWithLong: ...` to further investigate the problem.

    3. COYou should probably print the "raw" value of `[curRegistered objectForKey:@"ticket_id"]` to see if there are any oddball characters present.

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.
