Question

I need to pass a data between two view controllers.here is my code.

for first view controller

-(void)editBotton {

    Carttable *second=[[Carttable alloc]init];

    UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:second];
    nav.modalTransitionStyle=UIModalTransitionStyleCrossDissolve;

    [self.navigationController pushViewController:second animated:YES];

    NSString *temp=titlela.text;//titlela is UILabel

    NSLog(@"%@",temp);
    self.cart=second;
    cart.cnftitle=temp;
}

in my cartable view controller.h

@property(nonatomic,retain)NSString *cnftitle;

and i synthesized too

- (void)viewDidLoad
{
    [super viewDidLoad];

    NSLog(@"%@",cnftitle);
}

one NSlog prints my text in label where another prints as NULL….

am i missing anything?

Answer 1

You’re assigning the value after the view has loaded.

Move your assignment before the pushViewController:(as that’s the point where the view is loaded)
