how to make UIBarButtonItem send new address to UIWebView

Question

I have a uiwebview embedded within a navigation controller. I would like the ability to change the uiwebview by simply clicking a uibarbuttonitem. anyone have any idea how to do that?

heres the method i have right now.

-(void)action {

    if (item.link) {
        self.linkString = item.link;
    }
    NSString *urlAddress = @"%@/#comments", linkString;

    NSURL *address = [NSURL URLWithString:urlAddress];
    NSURLRequest *requestObj = [NSURLRequest requestWithURL:address];
    [contentLabel loadRequest:requestObj];
}

You could set the target selector or IBAction to change the request object:

  -(IBAction) action {
         NSString *urlAddress = @"http://google.com";

         NSURL *address = [NSURL URLWithString:urlAddress];
         NSURLRequest *requestObj = [NSURLRequest requestWithURL:address];
         [theWebView loadRequest:requestObj];
    }

or

  -(void) action {
         NSString *urlAddress = @"http://google.com";

         NSURL *address = [NSURL URLWithString:urlAddress];
         NSURLRequest *requestObj = [NSURLRequest requestWithURL:address];
         [theWebView loadRequest:requestObj];
    }
