[myView setNeedsDisplay]; 

[myView setNeedsLayout];

-(void)loadDataFromDatabaseAndDisplayIt{
      NSFetchRequest* fetchRequest = [[NSFetchRequest alloc] init];
      NSEntityDescription* entity = [NSEntityDescription
                  entityForName:@"User" inManagedObjectContext:self.context];
     [fetchRequest setEntity:entity];
      NSArray* data = [self.context executeFetchRequest:fetchRequest error:&error];

      User* firstUser = data[0];

      self.labelName.text = firstUser.name;
      self.labelPhoneNumber.text = firstUser.phoneNumber;
      //...
}

-(void)viewDidLoad{
     //...
     [self loadDataFromDatabaseAndDisplayIt];
}

-(void)someEventDidOccurThatShouldReloadData:(id)sender{
     [self loadDataFromDatabaseAndDisplayIt];
}
