title: Low memory / app getting crash?
body: <p>This is my code: -</p>
  
  <pre><code>NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init];
  [fetchRequest setEntity:[NSEntityDescription entityForName:@"PageDetail" inManagedObjectContext:managedObjectContext]];
  NSError *error = nil;
  NSMutableArray *mutableFetchResults = [[managedObjectContext executeFetchRequest:fetchRequest error:&amp;error] mutableCopy];//memory 55.7%
  [self setPagesArray:mutableFetchResults];
  [fetchRequest release];
  [mutableFetchResults release];
  </code></pre>
