Detail Disclosure Indicator MKMap to Custom View Controller - iphone

Question

EXTRA CODE ADDED
I am new to xcode. I have managed to create annotations on my map in various different colours. What I would like to do is have each annotation lead to somewhere new with a disclosure button. I have implemented a right arrow disclosure button now what I need to know is how I link that up so that each annotation will lead to a different view controller of my choice. Here is my current code on my MapViewController implementation.
MainMapViewController.m
#import "MainMapViewController.h"
#import "LocationAnnotation.h"
#interface MainMapViewController ()
#end
//Totnes Main Centre Coordinates
#define Totnes_LATITUDE 50.433741
#define Totnes_LONGITUDE -3.685797
//The Dartmouth Inn Coordinates
#define DARTMOUTH_INN_LATITUDE 50.430036;
#define DARTMOUTH_INN_LONGITUDE -3.683873;
//Pub Offers Co-Ordinates
#define TheKingBill_LATITUDE 50.431379
#define TheKingBill_LONGITUDE -3.685495
#define TheSevenStars_LATITUDE 50.431045
#define TheSevenStars_LONGITUDE -3.682945
#define TheLordNelson_LATITUDE 50.430931
#define TheLordNelson_LONGITUDE -3.683644
//Span
#define THE_SPAN 0.01f;
#implementation MainMapViewController
#synthesize mainMapView;
- (void)viewDidLoad
{
[super viewDidLoad];
//Set Delegate
mainMapView.delegate = self;
//Create the region
MKCoordinateRegion myRegion;
//Centre
CLLocationCoordinate2D centre;
centre.latitude = Totnes_LATITUDE;
centre.longitude = Totnes_LONGITUDE;
//Span
MKCoordinateSpan span;
span.latitudeDelta = THE_SPAN;
span.longitudeDelta = THE_SPAN;
myRegion.center = centre;
myRegion.span = span;
//Set The Map View
[mainMapView setRegion:myRegion animated:YES];
//Annotation
NSMutableArray * locations = [[NSMutableArray alloc] init];
LocationAnnotation * myAnn;
//The King Bill Annotation
myAnn = [[LocationAnnotation alloc] initWithTitle:#"The King Bill"
andSubtitle:#"Another Pub In Town"
andCoordinate:CLLocationCoordinate2DMake(TheKingBill_LATITUDE, TheKingBill_LONGITUDE)
andID:1];
[locations addObject:myAnn];
//The Seven Stars Annotations
myAnn = [[LocationAnnotation alloc] initWithTitle:#"The Royal Seven Stars Hotel"
andSubtitle:#"Hotel In Town"
andCoordinate:CLLocationCoordinate2DMake(TheSevenStars_LATITUDE, TheSevenStars_LONGITUDE)
andID:2];
[locations addObject:myAnn];
//The Lord Nelson Annotations
myAnn = [[LocationAnnotation alloc] initWithTitle:#"The Lord Nelson"
andSubtitle:#"Great Pub In Centre of Town"
andCoordinate:CLLocationCoordinate2DMake(TheLordNelson_LATITUDE, TheLordNelson_LONGITUDE)
andID:3];
[locations addObject:myAnn];
[self.mainMapView addAnnotations:locations];

MKPinAnnotationView *annView = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:#"pin"];
UIButton *rightButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
annView.rightCalloutAccessoryView = rightButton;
int annId = ((LocationAnnotation *)annotation).idNumber;
annView.pinColor = (annId == 1) ? MKPinAnnotationColorPurple

annView.canShowCallout = YES;
return annView;
}
#end

Answer 1

set rightbutton's tag to annID.
rightButton.tag = annId;
and then assign Selector to touchup event:
[rightButton addTarget:self action:#selector(YourMethod:) forControlEvents:UIControlEventTouchUpInside];
In YourMethod, you can use senders tag for navigating to different view
-(void)YourMethod:(UIButton*)sender
{
if(sender.tag==1)
{
//push viewcontroller1
}
else
{
//push viewcontroller
}
return;
}

Answer 2

As you can see, your right button is of type UIButton. Because of this fact you can addTarget to it:
[rightButton addTarget:self action:#selector(YourMethod) forControlEvents:UIControlEventTouchUpInside];
After user tap on rightButton YourMethod will be launched.
So for every pin you can add different button with different method, in the same way you are setting AnnotationColor
int annId = ((LocationAnnotation *)annotation).idNumber;
if (annId == 1)
{
annView.pinColor = MKPinAnnotationColorPurple;
UIButton *rightButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
annView.rightCalloutAccessoryView = rightButton;
[rightButton addTarget:self action:#selector(MethodWhereYouWillFireYouNewViewController) forControlEvents:UIControlEventTouchUpInside];
}
else if (annId == 2)
{
//similar as above
}

Answer 3

Check This:
-(void)clickOnMapAnnotation:(UIButton*)sender
{
int AnnotationClicked =sender.tag;
if(AnnotationClicked ==1)
{
//PushViewcontroller1
}
else
{
//PushViewcontroller1
}
}
(MKAnnotationView *) mapView:(MKMapView *)mapView viewForAnnotation:(id ) annotation {
if ([annotation isKindOfClass:[MKUserLocation class]])
return nil;
MKPinAnnotationView *annView = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:#"pin"];
int annId = ((LocationAnnotation *)annotation).idNumber;
annView.pinColor = (annId == 1) ? MKPinAnnotationColorPurple
: (annId == 2) ? MKPinAnnotationColorGreen
: MKPinAnnotationColorRed;
//The Detail Disclosure button that I want to lead to a new view controller.
UIButton *rightButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
[rightButton addTarget:self action:#selector(clickOnMapAnnotation:) forControlEvents:UIControlEventTouchUpInside];
rightButton.tag = annId;
annView.rightCalloutAccessoryView = rightButton;
annView.canShowCallout = YES;
return annView;
}
