    <p>I have a problem that whenever I'm inserting data using coredata, everything's going fine. But while retrieving, I'm getting the same object all the time retrieved. I'm inserting objects of actors with multiple attribues like id,name,address etc. in add method, I can see everything getting inserted(which actually I'm retrieving from an xml file). my set methods are like:=</p> <pre><code>[poi setActorCity:[NSString stringWithFormat:@"%@",[poi1 objectAtIndex:j]]]; </code></pre> <p>where, poi is an object of my <code>managedObjectClass POI1 </code>. Are those a problem? &amp; j index is simply for keeping track of xml values from poi1 array. Please help... </p> <ul> <li>(void)addEvent {</li> </ul> <p>[actorsArray removeAllObjects];</p> <p>NSEntityDescription *entity1 = [NSEntityDescription entityForName:@"POI1" inManagedObjectContext:self.managedObjectContext]; </p> <p>POI1 *poi = (POI1 *)[NSEntityDescription insertNewObjectForEntityForName:@"POI1" inManagedObjectContext:managedObjectContext];</p> <pre><code>for(NSInteger i=0;i&lt;[Actors count];i++) { NSMutableArray *poi1=[[NSMutableArray alloc]init]; poi1=[Actors objectAtIndex:i]; for(int j=0;j&lt;[poi1 count];j++) { if(j==1) { [poi setActorName:[NSString stringWithFormat:@"%@",[poi1 objectAtIndex:j]]]; } //Like this it inserts for every attribute } [actorsArray insertObject:poi atIndex:i]; [poi release]; } [self saveAction]; //saving the managedObjectContext </code></pre> <p>}</p> <p>This' my fetch method...</p> <p>-(void)fetchResult {</p> <pre><code>NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init]; </code></pre> <p>NSEntityDescription *entity1 = [NSEntityDescription entityForName:@"POI1" inManagedObjectContext:self.managedObjectContext];</p> <p>[fetchRequest setEntity:entity1];</p> <pre><code>NSArray *items = [self.managedObjectContext executeFetchRequest:fetchRequest error:&amp;error]; for(NSInteger k=0;k&lt;[items count];k++) { POI1 *_poi=[[POI1 alloc]init]; _poi = [items objectAtIndex:k]; NSString *str=[NSString stringWithFormat:@"%@",[_poi actorName]]; //This' for testing... Shows me same name every time.., } [fetchRequest release]; </code></pre> <p>}</p>

    2. COWe need more information about the problem; can you show us the loop where you create your poi objects - I think that Vincent might be on the right track but we'd need to see more code to be sure :)

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.
