Question

I’m trying to make an app that has multiple pins/locations (about 50-100). Which way is the easiest way to go? Can I have some sort of database where I get my locations from?
At the moment I have a code that works great, but It only shows one location/pin. How do I add more on the current code? Or as I said earlier, is it any other easier way with some sort of database?

Here’s the code:
SecoundViewController.h :

#import <UIKit/UIKit.h>
#import <MapKit/MapKit.h>

@interface SecondViewController : UIViewController {

MKMapView *mapview;
}

@property (nonatomic, retain) IBOutlet MKMapView *mapview;

-(IBAction)setMap:(id)sender;

-(IBAction)getlocation;

@end

SecoundViewController.m :

#import "SecondViewController.h"
#import "NewClass.h"

@interface SecondViewController ()

@end

@implementation SecondViewController

@synthesize mapview;

-(IBAction)getlocation {

mapview.showsUserLocation = YES;

}

-(IBAction)setMap:(id)sender {

switch (((UISegmentedControl *) sender).selectedSegmentIndex) {

    case 0:

        mapview.mapType = MKMapTypeStandard;

        break;

    case 1:

        mapview.mapType = MKMapTypeSatellite;

        break;

    case 2:

        mapview.mapType = MKMapTypeHybrid;

        break;

    default:

        break;

}

}

-(void)viewDidLoad {
[super viewDidLoad];

[mapview setMapType:MKMapTypeStandard];
[mapview setZoomEnabled:YES];
[mapview setScrollEnabled:YES];

MKCoordinateRegion region = { {0.0, 0.0 }, {0.0, 0.0 } };
region.center.latitude = 56.15881;
region.center.longitude = 13.76454;
region.span.longitudeDelta = 0.01f;
region.span.latitudeDelta = 0.01f;
[mapview setRegion:region animated:YES];

NewClass *ann = [[NewClass alloc] init];
ann.title = @"Harrys Pub & Restaurang";
ann.subtitle = @"Järnvägsgatan 7";
ann.coordinate = region.center;
[mapview addAnnotation:ann];

}

@end

It all depends how you plan to enter and maintain info about the pins.
You can use XML, JSON, plist, CoreData…
