Question

I am developing an app that saves a URL using CoreData. I am defining NSManagedObjectContext, NSManagedObjectModel, NSPersistentStoreCoordinator in CoreDataRepository object class instead of AppDelegate. I am saving this URL using reference of CoreDataRepository. I am using the code below for getting CoreData

-(void)getcoredata
 {
  _coredatarep = [[CoreDataRepository alloc] init];

  NSManagedObjectContext *context=[_coredatarep managedObjectContext];
  NSFetchRequest *request=[[NSFetchRequest alloc] init];
  NSEntityDescription *entity=[NSEntityDescription entityForName:@"UrlData" inManagedObjectContext:context];
  [request setEntity:entity];

  NSError *error;
  NSArray *recordsDataArray=[context executeFetchRequest:request error:&error];

  urlMutableArray = (NSMutableArray *)recordsDataArray;

  for (int i=0; i<[urlMutableArray count]; i++)
  {
      urlString = [NSString stringWithFormat:@"%@", [urlMutableArray objectAtIndex:0]];
       NSLog(@"urlString is %@",urlString);
      _urlLabel.text=urlString;
  }


}

In the output, label text shows as

<NSManagedObject: 0x9920620> (entity: UrlData; id: 0x991faf0 <x-coredata://A00EB59A-C480-4237-A749-8A40BF908655/UrlData/p1> ; data: <fault>)

Any idea why this is happening?

As I said in your other thread, it’s printing what you told it to print. [urlMutableArray objectAtIndex:0] is a UrlData object and that’s its description. If you want a string that’s stored inside the UrlData, you need to ask it for one of its properties…whatever you’ve defined them to be in your data model.
