sending value of NSString to ViewController PopOver

Question

Im looking to access the value of an NSString from the parent ViewController inside the PopOver View Controller. Below is the code i have that generates the popover when selecting a row from a tableView. I need to be able to access the varToPass value in the editPersonViewController.

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

    UIView *anchorr = tableView;
    UIViewController *viewControllerForPopover =
    [self.storyboard instantiateViewControllerWithIdentifier:@"editPersonViewController"];

    popover = [[UIPopoverController alloc]
               initWithContentViewController:viewControllerForPopover];
    [popover presentPopoverFromRect:anchorr.frame
                             inView:anchorr.superview
           permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];


    Person *person = [arrayOfPersons objectAtIndex:indexPath.row];


    // I Need to Send/Access This Value In editPersonViewController
    NSString *varToPass = person.personID;


}

Answer 1

Add a public property in your editPersonViewController.h file called personID like so

@property (nonatomic, strong) NSString *personID;

Then, just reorder your instantiation of the editViewController to look like this:

UIView *anchorr = tableView;
Person *person = [arrayOfPersons objectAtIndex:indexPath.row];
EditPersonViewController *viewControllerForPopover =
(EditPersonViewController *)[self.storyboard instantiateViewControllerWithIdentifier:@"editPersonViewController"];

viewControllerForPopover.personID= person.personID;

popover = [[UIPopoverController alloc]
           initWithContentViewController:viewControllerForPopover];
[popover presentPopoverFromRect:anchorr.frame
                         inView:anchorr.superview
       permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
