I have two UIViewController: "MenuViewController" and "DetailViewController".

I'm trying to set DetailViewController's label text as a NSString in the MenuViewController, but doesn't work.

Does anyone know how to do this?

Can you show us the code that doesn't work, please? – emrys57 Nov 26 '12 at 21:14 — emrys57, Nov 26 '12 at 21:14

it is very simple, add @property (retain) NSString* string; in the DetailedViewController and before navigate to it set this property like this

DetailedViewController *dvc = [[DetailedViewController alloc] init];
[dvc setString:@"someString"];
[self pushViewController:dvc]

in DetailedViewController in ViewDidLoad set the label:

[[self label] setText:[self string]];

Couple of points, add a 'nonatomic' keyword along side retain. Also, if this is ARC, use 'strong' instead of 'retain'. – WDUK Nov 26 '12 at 22:39
