How to send a user to a Facebook page when a button is clicked

I am new to iOS development, so please bear with me.

I am creating a simple application. There is a facebook button, and I would like this button to send the user to my facebook page, either in the browser, or if they have a facebook application that opens.

I know there might be a lot to explain, but if someone could point me in the right direction, that would be great, thanks.

Starting with version 4.0 for Facebook, you can go to pages with this URI scheme:

fb://page/{fbid}

Just make sure you check to make sure that the device you are working with can respond to it:

[[UIApplication sharedApplication] canOpenURL:[NSURL urlWithString:@"fb://page/{fbid}"]];

Your method might look something like this:

- (IBAction)openFBPage:(id)sender {
    if ([[UIApplication sharedApplication] canOpenURL:[NSURL urlWithString:@"fb://page/{fbid}"]]) {
        [[UIApplication sharedApplication] openURL:[NSURL urlWithString:@"fb://page/{fbid}"]];
    } else {
        NSLog(@"Facebook isn't installed.");
        // or do the sensible thing and openURL the HTTP version of the page in safari
}

... ​​Interface Builder.
