Question

I am implementing FB kind of functionality where I

1. populate a list of menu from database on left side.
2. clicking any of menu loads a related web page inside webview.

Both Menu’s and Webview are in different viewcontroller

When menu gets clicked, I send notification message to first viewcontroller and inside notification message I write code to loadRequest.

However this is not working. I am able to loadRequest successfully from first Viewcontroller.however it is not possible to do from another viewcontroller.

here is my code:

ViewController 1:

in ViewLoad

NSNotificationCenter *note = [NSNotificationCenter defaultCenter];
[note addObserver:self selector:@selector(eventDidFire:) name:@"ILikeTurtlesEvent" object:nil];

    - (void) eventDidFire:(NSNotification *)note {
            web.delegate=self;
        [web loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"http://www.google.com"]]];
     }

in ViewController 2:

NSNotificationCenter *note = [NSNotificationCenter defaultCenter];
[note postNotificationName:@"ILikeTurtlesEvent" object:self];

This could be the another option for what you are trying to do:

viewcontroller1.h:
-(void)clickmenu:(id)sender;

viewcontroller1.m:
-(void)clickmenu:(id)sender
{
  viewcontroller2 *obj = [[viewcontroller2 alloc] initWithNibName: @"viewcontroller2" bundle: [NSBundle mainBundle]];
[obj Loadwebview:[NSURL urlwithstring:@"http://www.google.com"]];
}


ViewController2.h:
-(void)Loadwebview:(NSURL *)url;
viewcontroller2.m:
-(void)Loadwebview:(NSURL *)url
{
      web.delegate=self;
    [web loadRequest:[NSURLRequest requestWithURL:url]];
}
