MKAnnotation not displaying on map view - ios

Question

I am trying to create a custom annotation for a simple map view of mine, but the annotaiton pin is not showing up on the map when i run the simulator.
I have a MapViewAnnotation class which implements the MKAnnotation protocol, and I have another MapViewController class where I programmatically create a mapView and display the map.
MapViewAnnotation.h :
#import <Foundation/Foundation.h>
#import <MapKit/MapKit.h>
#interface MapViewAnnotation : NSObject <MKAnnotation>
#property (nonatomic, copy) NSString *title;
#property (nonatomic, readonly) CLLocationCoordinate2D coordinate;
-(id) initWithTitle: (NSString *) title AndCoordinate: (CLLocationCoordinate2D) coordinate;
#end
MapViewAnnotation.m :
#import "MapViewAnnotation.h"
#implementation MapViewAnnotation
#synthesize coordinate = _coordinate;
#synthesize title = _title;
-(id) initWithTitle:(NSString *)title AndCoordinate:(CLLocationCoordinate2D)coordinate{
self = [super init];
_title = title;
_coordinate = coordinate;
return self;
}
#end
MapViewController.h :
#import <UIKit/UIKit.h>
#import <MapKit/MapKit.h>
#interface MapViewController : UIViewController
#property (weak, nonatomic) MKMapView *mapView;
-(void) goToLocation;
#end
MapViewController.m :
#import "MapViewController.h"
#import "MapViewAnnotation.h"
#define LATITUDE 42.3889;
#define LONGITUDE -72.5278;
#interface MapViewController ()
#end
#implementation MapViewController
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
self.mapView = [[MKMapView alloc] initWithFrame:self.view.frame];
[self.view addSubview:self.mapView];
[self goToLocation];
[self.mapView addAnnotations:[self createAnnotations]];
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
-(void) goToLocation {
MKCoordinateRegion newRegion;
newRegion.center.latitude = LATITUDE;
newRegion.center.longitude = LONGITUDE;
newRegion.span.latitudeDelta = 0.05f;
newRegion.span.longitudeDelta = 0.05f;
self.mapView.showsPointsOfInterest = YES;
[self.mapView setRegion:newRegion animated:YES];
}
-(NSMutableArray *) createAnnotations {
NSMutableArray *annotations = [[NSMutableArray alloc] init];
NSString *path = [[NSBundle mainBundle] pathForResource:#"location" ofType:#"plist"];
NSArray *locations = [NSArray arrayWithContentsOfFile:path];
for (NSDictionary *row in locations){
NSNumber *latitude = [row objectForKey:#"latitude"];
NSNumber *longitude = [row objectForKey:#"longitude"];
NSString *title = [row objectForKey:#"title"];
CLLocationCoordinate2D coord;
coord.latitude = latitude.doubleValue;
coord.longitude = longitude.doubleValue;
MapViewAnnotation *annotation = [[MapViewAnnotation alloc] initWithTitle:title AndCoordinate:coord];
[annotations addObject: annotation];
}
return annotations;
}
#end
I am taking am going through a plist where I have coordinates for one test location that I am trying to show on my map, but the pin is not displaying on the map. Again, I am doing this all programmatically, no xib, or storyboards (although that should not be the problem).
I do not know why the annotation is not showing up. I tried looking on stack for some other situations like mine but was unlucky to find anything that could help.
Thank you.

Answer 1

Answer was pretty simple,
In my plist I had the coordinates
latitude: 42.37
longitude: 72.536
when it should of actually been -72.536 for longitude.
