Passing objects using didSelectRowAtIndexPath:

Question

How do I pass between objects from uitableviews to my detail views? I've set up a conditional push, as you can see in my method:

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{

    Budget * tempBudget = [self.budgetPlan.budgets objectAtIndex:indexPath.row];

    NSString *targetViewControllerIdentifier = nil;
    if (tempBudget.hasBeenInitialized != true) {
        targetViewControllerIdentifier = @"budgetInitializerView";
        UIViewController *vc = [self.storyboard instantiateViewControllerWithIdentifier:targetViewControllerIdentifier];
        [self.navigationController pushViewController:vc animated:YES];

        // how do I pass the tempBudget to the pushed view?


    } else {
        targetViewControllerIdentifier = @"budgetDetailsView";
        UIViewController *vc = [self.storyboard instantiateViewControllerWithIdentifier:targetViewControllerIdentifier];
        [self.navigationController pushViewController:vc animated:YES];

        // how do I pass the tempBudget to the pushed view?

    }
}

I'm having trouble with the UIViewController *vc = [self.storyboard instantiateViewControllerWithIdentifier:targetViewControllerIdentifier];

Usually, I just set vc.budget = tempbudget as the answer below suggests, but it does not seem to understand the budget property.

Can you elaborate on "does not seem to understand the budget property"? Compiler warning? Crash? Nothing displayed on the new view? — jscs, Mar 27 '12 at 18:09
Nothing is displayed in the new view. It does not seem to be passed. — lorenzoid, Mar 27 '12 at 20:52

I would create a BaseViewController that has a @property of type of your object and send your object in that way.

// In your .h
BaseViewController : UIViewController {
}

@property (nonatomic, strong) Budget *budget;

//In your .m
@synthesize budget;

Also, you can move this line out of your if/else statement, since it's the same thing:

vc.budget = tempBudget;
[self.navigationController pushViewController:vc animated:YES];

set your budget property right before you push your view controller

It does not seem to be passing the data still for some reason if I do vc.Budget = tempBudget. – lorenzoid Mar 27 '12 at 18:05
Also, I can't move the vc.budget = tempBudget as it is a local variable. – lorenzoid Mar 27 '12 at 18:06
If you have a property created in Class you most certainly can pass a local variable to it. – El Guapo Mar 27 '12 at 18:19
I meant that I couldn't exclude the vc.budget = tempBudget from the if/then scope. – lorenzoid Mar 27 '12 at 18:59
