iOS Mapping Application New View from Annotation - ios

Question

I am totally new to iOS development, and am creating a mapping application for a local river. The point of the application is to allow users to map out a route on the river by selecting different points. I am using MapKit to work on this, but have run into some issues. My main issue is how to add a button to an annotation so that once clicked, a detail window will open and the user can learn more about the point as well as add it to the trip. Here's my code, any thoughts will help!
#import "ViewController.h"
#import "CoreLocation/CLLocation.h"
#interface ViewController ()
#end
#implementation ViewController
- (void)viewDidLoad
{
[super viewDidLoad];
self.mapView.delegate = self;
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
- (void)mapView:(MKMapView *)mapView didUpdateUserLocation:(MKUserLocation *)userLocation
{
// Add an annotation
MKPointAnnotation *point = [[MKPointAnnotation alloc] init];
point.coordinate = userLocation.coordinate;
point.title = #"Where am I?";
point.subtitle = #"I'm here!!!";
[self.mapView addAnnotation:point];
point.coordinate = CLLocationCoordinate2DMake(33.62258872997,-86.599988937378);
point.title = #"Civitan Park";
point.subtitle = #"Trussville, AL";
[self.mapView addAnnotation:point];
}
#end

Your map view delegate should implement –mapView:viewForAnnotation: and return an annotation view that has one of its accessory view properties set. The normal thing is to set the rightCalloutAccessoryView property to a UIButton whose type is UIButtonTypeDetailDisclosure. You map delegate should also implement -mapView:annotationView:calloutAccessoryControlTapped:, which will be called when the user taps the button in the accessory view. You can then push a detail view controller onto the navigation stack, or whatever else you like.
