Showing a specific location using UIMapKit

I have an iPhone application with a number of views, each view represented a part of the world. When my user taps the button to take them to that view, I want to show a map开发者_运维技巧 with a preset location...i.e. when the tap to go to New York it shows a map of New York

Is this possible to do? Specify a latitude and longitude coordinate? or by some other method?

I have the following code so far which takes my users current location and displays the map of that, and i can choose between hybrid, normal or satellite through a segmented control.

-(IBAction)getLocation {
    creteMapView.showsUserLocation = YES;
}

-(IBAction)setMap:(id)sender {

    switch (((UISegmentedControl *)sender).selectedSegmentIndex)
    {
        case 0:
        {
            creteMapView.mapType = MKMapTypeStandard;
            break;
        }
        case 1:
        {
            creteMapView.mapType = MKMapTypeSatellite;
            break;
        }
        case 2:
        {
            creteMapView.mapType = MKMapTypeHybrid;
            break;
        }
    }
}

That all works perfectly, but instead of the current location I want to just set a already defined one. Any ideas?

Thanks

add class that implement MKAnnotation protocol like : http://trac.ilesansfil.org/browser/branches/ilesansfil_iphone_app/STABLE_1.3/Models/LocationAnnotation.h

http://trac.ilesansfil.org/browser/branches/ilesansfil_iphone_app/STABLE_1.3/Models/LocationAnnotation.m

import header file and try

CLLocationCoordinate2D coordinate1;
    coordinate1.longitude = 3.35;
    coordinate1.latitude = 44.85;
    LocationAnnotation *loc1 = [[LocationAnnotation alloc] initWithCoordinate:coordinate1];
    [creteMapView addAnnotation:loc1];

this will add a pin to your map

You can also remove user location if you want with :

creteMapView.showsUserLocation = NO;

Use setRegion in your MKMapView. It needs a MKCoordinateRegion that you make with MKCoordinateRegionMake with a center coordinate (lat, long) and a span (area covered). You can get the latitude and longitude from an API like Google maps, but that would need a full tutorial.
