Question

I was to pass a NSString from RootViewController(UITableViewController) to DetailViewController .

t RootViewController.m

    - (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender { 
    DetailViewController *detailViewController = segue.destinationViewController; 
    detailViewController.name = @"foo"; 
    }

DetailViewController.h:

NSString *name;
@property (nonatomic,strong) NSString *name;

DetailViewController.m

@synthesize name = _name;
NSLog(@"%@", name);

The result of NSlog is null. Appreciate for any hint. Thanks a lot.

Answer 1

I can’t really see when you are executing your nslog. So i’m thinking you ask for the name before you are setting it.

And another thing. If you write:

@synthesize name = _name;

you should use this too:

NSLog(@"%@", _name);
