Passing a string from IBAction to a separate View Controller

I am trying to pass a String from an IBAction in my DetailsViewController to the viewDidLoad in my WebViewController to call up a URL in the WebView.

Does anybody know how I can do this?

My Code:

// DetailsViewController.m

- (IBAction)edu1Link:(id)sender {

    NSString *webURL = [[NSString webURL] initWithString:@"http://www.apple.com"];


    _webViewController = [[WebViewController alloc]
                          initWithNibName:@"WebViewController" bundle:nil];

    [[self navigationController] presentModalViewController:_webViewController animated:YES];            
}


// WebViewController.m

- (void)viewDidLoad
{
    [_webView loadRequest:[NSURLRequ开发者_StackOverflowest requestWithURL:[NSURL URLWithString:webURL]]];
    [super viewDidLoad];
    // Do any additional setup after loading the view from its nib.
}

You could declare a property in your WebViewController and set that property in the action before presenting the view controller.

I guess the best way would be to use a delegate methode here is a tutorial how you would do that

What albertamg is referring to is Objective-C properties. They are very powerful. Take a peak here: http://cocoacast.com/?q=node/103

Properties are like instance fields in Java. They're helpful in side-stepping zero-parameter-methods.
