    <p>I'm writing an app that communicate with a server. The server uses json, so I take this json in my app and I serialize the result into a <code>NSMutableDictionary</code> that then is used to create a new entity.</p> <p>This is the code :</p> <pre><code>if (context == nil) { context = [(AppDelegate *)[[UIApplication sharedApplication] delegate] managedObjectContext]; } UserTable *ut = [NSEntityDescription insertNewObjectForEntityForName:@"UserTable" inManagedObjectContext:context]; ut.user = [Diz objectForKey:@"user"]; ut.email = [Diz objectForKey:@"email"]; ut.phone = [Diz objectForKey:@"phone"]; NSError *error = nil; if (![context save:&amp;error]) { NSLog(@"Unresolved error %@, %@", error, [error userInfo]); } </code></pre> <p>All works perfectly in iOS 4.3, iOS 6.0 and 6.1. In iOS 5.0.1 this code causse an exc_bad_Address localized in <code>[context save:&amp;error]</code> or localized sometimes in <code>ut.phone=[Diz objectForKey:@"phone"]</code>.</p> <p>I'm using only one context (I have test threading composition with "isMainThread" function), What I can do? My error log is empty,the app simply does a crash.</p> <p>EDIT</p> <p>Thanks for the suggestions. I'm already removing my app from the device, but i'll try to do a migration. I have enabled exception breakpoint, but it's the same... The app crash without log any error (i have also NsZombie enabled). During the crash the green breakpoint is setted on an attribute of the Entity "UserTable" ,if i remove this attribute from saving the breakpoint is setted in the save function. </p> <p>EDIT</p> <p>After many tests i have detect a standard behavior for this crash. My Entity UserTable has 31 attributes, if i delete one attribute all works correctly... i have already tried to recreate the entity with another name and with others attribute's name but the behavior is the same... What does it means? There's a limit for entity's attributes number? Any other suggestions?</p>

    1. COYou can try setting a breakpoint on all Objective-C crashes to help debug.

    2. COdid you mean to write "contesto" or "context" where you're calling `insertNewObjectForEntityForName`?

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
