PrepareForSegue mystery

Question

I\'ve got a prepareForSegue method in two different VCs. One uses an if statement, while the other is intended to use a switch. The code is virtually i

Answer 1

To solve the second error, try adding braces in your switch-case to define a context to the variables:

-(void) prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    NSManagedObjectContext *localContext = [NSManagedObjectContext MR_contextForCurrentThread];
    [SearchSpecs MR_truncateAllInContext:localContext];
    [localContext MR_saveToPersistentStoreAndWait];

    switch ([sender tag])
    {
        case aVsAButton_tag:
            {
                UINavigationController *navController = (UINavigationController *)segue.destinationViewController;
                AvsAViewController *aVSaVC = (AvsAViewController *)navController.topViewController;
                aVSaVC.delegate = self;
                SearchSpecs *thisSpec = (SearchSpecs *)[SearchSpecs MR_createInContext:localContext];
                aVSaVC.currentSpec = thisSpec;
            }
            break;

        default:
            break;
    }

}
