How do I link Xcode map annotations callout to an info page?

At the moment I am creating a Map with annotations in Xcode. I'm also using Xcode 4 at the moment due to code I copied from an old source.

Here's a link:
http://youtu.be/B5RfXxQWjL8
which I have worked from. In the video at 14:10 he clicks the annotation action button however no callout page pops up.

I am sure the answer is simple but how do I create an information page and then how do I link each annotation to have a different callout associated action to the information page?

The guy who made the video also put the source code online which is handy.

I may also include below the code so far which actually has minimal changes thus far.

Code below:

#import "AnnotationViewController.h"
#import "Annotation.h"

@implementation AnnotationViewController
@synthesize mapView;

-(void)viewDidLoad {

[super viewDidLoad];
[mapView setMapType:MKMapTypeStandard];
[mapView setZoomEnabled:YES];
[mapView setScrollEnabled:YES];
[mapView setDelegate:self];


// Chapel of Isolde
MKCoordinateRegion ChapelofIsolde = { {0.0, 0.0} , {0.0, 0.0} };
ChapelofIsolde.center.latitude = 53.3573373;
ChapelofIsolde.center.longitude = -6.3622526;
ChapelofIsolde.span.longitudeDelta = 4.02f;
ChapelofIsolde.span.latitudeDelta = 4.02f;
[mapView setRegion:ChapelofIsolde animated:YES];

Annotation *ann1 = [[Annotation alloc] init];
ann1.title = @Chapel of Isolde;
ann1.subtitle = @Legen of Tristen & Isolde;
ann1.coordinate = ChapelofIsolde.center;
[mapView addAnnotation: ann1];


// Clonmacnoise
MKCoordinateRegion Clonmacnoise = { {0.0, 0.0} , {0.0, 0.0} };
Clonmacnoise.center.latitude = 53.326277;

Clonmacnoise.span.longitudeDelta = 4.02f;
Clonmacnoise.span.latitudeDelta = 4.02f;
[mapView setRegion:Clonmacnoise animated:YES];

Annotation *ann2 = [[Annotation alloc] init];
ann2.title = @Clonmacnoise;
ann2.subtitle = @546 AD Monastery;
ann2.coordinate = Clonmacnoise.center;
[mapView addAnnotation:ann2];


//Cloon & Laghtanabba Bog
MKCoordinateRegion CloonLaghtanabbaBog = { {0.0, 0.0} , {0.0, 0.0} };
CloonLaghtanabbaBog.center.latitude = 53.537161;
CloonLaghtanabbaBog.center.longitude = -10.081596;
CloonLaghtanabbaBog.span.longitudeDelta = 4.02f;
CloonLaghtanabbaBog.span.latitudeDelta = 4.02f;
[mapView setRegion:CloonLaghtanabbaBog animated:YES];

Annotation *ann3 = [[Annotation alloc] init];
ann3.title = @Cloon & Laghtanabba Bog;
ann3.subtitle = @National Parks;
ann3.coordinate = CloonLaghtanabbaBog.center;
[mapView addAnnotation:ann3];
