populating a pin drop and call out from plist map view

[gbenna]

In my app I have a map view which I want to have a pin drop and have an annotation call out of a title and subtitle. Here is what I have so far.



// Location Five.h


#import <UIKit/UIKit.h>
#import <AVFoundation/AVFoundation.h>
#import <AudioToolbox/AudioToolbox.h>
#import <MapKit/MapKit.h>
#import <CoreLocation/CoreLocation.h>
#import <MapKit/MKAnnotationView.h>

@interface Location_Five : UIViewController <AVAudioPlayerDelegate, MKMapViewDelegate, MKAnnotation> {


CLLocationCoordinate2D coordinate;
NSString *title;
NSString *subtitle;
NSString *latitude;
NSString *longitude;
NSArray *tableDataOne;
MKMapView *mapView;
}

@property (nonatomic, assign) CLLocationCoordinate2D coordinate;
@property (nonatomic, copy) NSString *title;
@property (nonatomic, copy) NSString *subtitle;
@property (nonatomic) BOOL animatesDrop;
@property (nonatomic, retain) IBOutlet MKMapView *mapView;
@property (nonatomic, retain) NSArray *tableDataOne;
@property (nonatomic, retain) NSString *latitude;
@property (nonatomic, retain) NSString *longitude;

@end

When I run the app and I open the viewController Location_Five a red pin drops I don't know where because there is no map view even tho I have placed into the IB and linked the map view to it. And there is no call out. Can anyone help me here. I think it is because maybe I am calling the wrong place in my plist.
