Custom Pin in Mapkit - iphone

Question

I am primarily a JAVA programmer but took on a bus tracker project for the iPhone, so I am not very comfortable with this yet. Please forgive any noobish mistakes. The following code is how it was when I got pins to work. Any changes I made to attempt showing images has been removed.
#import "UICBus_FirstViewController.h"
#interface UICBus_FirstViewController ()
#end
#implementation UICBus_FirstViewController
#synthesize timer;
- (void)viewDidLoad
{
[super viewDidLoad];
CLLocationCoordinate2D zoomLocation;
zoomLocation.latitude = 41.869271;
zoomLocation.longitude= -87.666436;
// 2
MKCoordinateRegion viewRegion = MKCoordinateRegionMakeWithDistance(zoomLocation, 0.85*METERS_PER_MILE, 0.85*METERS_PER_MILE);
// 3
MKCoordinateRegion adjustedRegion = [__mapView regionThatFits:viewRegion];
// 4
[__mapView setRegion:adjustedRegion animated:YES];
CGRect frame = self.view.bounds;
frame.size.height = frame.size.height - 40;
// Do any additional setup after loading the view, typically from a nib.
[self initRoutes];
timer = [NSTimer scheduledTimerWithTimeInterval: 5 target:self selector:#selector(updateLocations) userInfo:nil repeats: YES];
}
- (void)viewWillAppear:(BOOL)animated {
}
- (void)updateLocations {
[self updateBuses];
[self._mapView removeAnnotations:_Anns];
_Anns = [[NSMutableArray alloc] init];
for (int i = 0; i < _Buses.count; i++){
UICBus_Bus *Temp = _Buses[i];
CLLocationCoordinate2D ctrpoint;
ctrpoint.latitude = [Temp.getLat floatValue];
ctrpoint.longitude = [Temp.getLon floatValue];
MKAnnotation *addAnnotation = [[MKAnnotation alloc] initWithTitle:Temp.getMac andCoordinate:ctrpoint];
[_Anns addObject:addAnnotation];
}
[self._mapView addAnnotations:_Anns];
}
// ********************** Still need to add code to determine if bus is active or not **********************
- (void)updateBuses {
NSURL *url = [NSURL URLWithString:#"http://bus.uic.edu/api/latest"];
NSData *content = [NSData dataWithContentsOfURL:url];
NSError *JSONe;
_BusesInput = [NSJSONSerialization JSONObjectWithData:content options:NSJSONReadingMutableContainers error:&JSONe];
_Buses = [[NSMutableArray alloc] init];
UICBus_Bus *Temp;
if(_BusesInput.count < 1){
NSLog(#"No Buses Found/Empty JSON");
}else{
for (NSString* key in _BusesInput){
Temp = [[UICBus_Bus alloc] init:[_BusesInput objectForKey:key]];
[_Buses addObject:Temp];
}
}
}
- (void)mapView:(MKMapView *)mv didAddAnnotationViews:(NSArray *)views{
MKAnnotationView *annotationView = [views objectAtIndex:0];
id <MKAnnotation> mp = [annotationView annotation];
[mv selectAnnotation:mp animated:YES];
}
- (void)viewDidUnload {
[self set_mapView:nil];
[super viewDidUnload];
}
#end
So, can I get this code to display a custom pin or do I need to rework it? and how?

Answer 1

You can directly work with didAddAnnotationViews method and didSelectAnnotation possibly while displaying and selecting custom image resp.
I found this link to help you best with How do I add custom pins to the iPhone MapKit?
Hope this helps.
