Right now I can show current and destination now I want a dummy pin in midway say any location but I want to know how to add 3 pins in map
if(annotation != mapView.userLocation)
{
NSLog(#"marked");
static NSString *defaultPinID = #"com.invasivecode.pin";
pinView = (MKPinAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:defaultPinID];
if ( pinView == nil )
pinView = [[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:defaultPinID] autorelease];
pinView.pinColor = MKPinAnnotationColorGreen;
pinView.canShowCallout = YES;
pinView.animatesDrop = YES;
}

I am trying to add a custom image instead of the regular pin on the map. But it remains a red pin... What am I missing?
- (MKAnnotationView *) mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>) annotation{
static NSString* AnnotationIdentifier = #"AnnotationIdentifier";
MKPinAnnotationView *annView = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:AnnotationIdentifier];
annView.animatesDrop = TRUE;
annView.image = [UIImage imageNamed:#"CustomPin.png"];
return annView;
}
MKMapView: Instead of Annotation Pin, a custom view
-(MKAnnotationView *)mapView:(MKMapView *)mV viewForAnnotation:(id <MKAnnotation>)annotation
{
MKAnnotationView *pinView = nil;
if(annotation != mapView.userLocation)
{
static NSString *defaultPinID = #"com.invasivecode.pin";
pinView = (MKAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:defaultPinID];
if ( pinView == nil )
pinView = [[MKAnnotationView alloc]
initWithAnnotation:annotation reuseIdentifier:defaultPinID];
//pinView.pinColor = MKPinAnnotationColorGreen;
pinView.canShowCallout = YES;
//pinView.animatesDrop = YES;
pinView.image = [UIImage imageNamed:#"pinks.jpg"]; //as suggested by Squatch
}
else {
[mapView.userLocation setTitle:#"I am here"];
}
return pinView;
}
Hi just remove one line from your code... annView.animatesDrop = TRUE;
Remain Code-
-(MKAnnotationView *) mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>) annotation{
static NSString* AnnotationIdentifier = #"AnnotationIdentifier";
MKPinAnnotationView *annView = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:AnnotationIdentifier];
annView.image = [UIImage imageNamed:#"CustomPin.png"];
return annView;
}
I found it helpful to look at Apples Documentation and download the sample code.
http://developer.apple.com/library/ios/#samplecode/MapCallouts/Introduction/Intro.html#//apple_ref/doc/uid/DTS40009746
They are implementing a custom annotation for their map.
I want to show the title of the pin(MKAnnotation)every time when I added the annotation.I added the following code for that.But it is not working.Please help me to find out.
I just added the pin like this.
ann = [[DisplayMap alloc] init];
ann.title = #"aaa";
ann.subtitle = #"bbbn";
[mapView addAnnotation:ann];
after that i added the following code in this method
-(MKAnnotationView *)mapView:(MKMapView *)mV viewForAnnotation:(id <MKAnnotation>)annotation
{
if(annotation != mapView.userLocation)
{
static NSString *defaultPinID = #"com.invasivecode.pin";
pinView = (MKPinAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:defaultPinID];
if ( pinView == nil )
pinView = [[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:defaultPinID] autorelease];
pinView.pinColor = MKPinAnnotationColorRed;
pinView.canShowCallout = YES;
pinView.animatesDrop = YES;
pinView.selected = YES;
[mapView selectAnnotation:annotation animated:YES];
//[pinView setImage:[UIImage imageNamed:#"user.png"]];
}
}
what mistake I have done?
My code for annotation is:
- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id<MKAnnotation>)annotation {
static NSString *identifier = #"RoutePinAnnotation";
if ([annotation isKindOfClass:[UICRouteAnnotation class]]&&[(UICRouteAnnotation *)annotation annotationType] != UICRouteAnnotationTypeWayPoint)
{
MKPinAnnotationView *pinAnnotation = (MKPinAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:identifier];
if(!pinAnnotation) {
pinAnnotation = [[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:identifier] autorelease];
}
if ([(UICRouteAnnotation *)annotation annotationType] == UICRouteAnnotationTypeStart) {
pinAnnotation.pinColor = MKPinAnnotationColorGreen;
} else if ([(UICRouteAnnotation *)annotation annotationType] == UICRouteAnnotationTypeEnd) {
pinAnnotation.pinColor = MKPinAnnotationColorRed;
}
pinAnnotation.animatesDrop = YES;
pinAnnotation.enabled = YES;
pinAnnotation.canShowCallout = YES;
return pinAnnotation;
}
}
App runs fine first but when we zoom the map it crashes.
Terminating app due to uncaught exception NSInvalidArgumentException, reason: -[MKAnnotationView setPinColor:]
Please help me!! Thanks
ok desperation. This is killing me.. I totally do not understand MapKit at all.. Despite reading so many tutorial.. =(
For more information, I have 2 annotation classes - MyAnnotation and MyAnnotation2, it doesnt seems to work too.. Somebody plz help.. I am afraid I have no hair left soon =(

- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation;
is called every time the MKMapView needs to show a view for an annotation, it passes you that annotation for a reason. So instead of iterating through them and returning only the color for the first one in your array (you need to understand that returning from a function/method doesn't let the loop iterate more), use the parameter instead.
Also a good practice is to use
- (MKAnnotationView *)dequeueReusableAnnotationViewWithIdentifier:(NSString *)identifier;
so the AnnotationViews don't get created again from scratch, especially memory-wise!
- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation
{
BOOL isGreen = YES;
if([annotation isKindOfClass:[MyAnnotation class]])
isGreen = NO;
MKPinAnnotationView *pinView = nil;
if (isGreen) {
static NSString *greenPin = #"greenPin";
pinView = (MKPinAnnotationView *) [mapView dequeueReusableAnnotationViewWithIdentifier:greenPin];
if (!pinView) {
pinView = [[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:greenPin] autorelease];
pinView.pinColor = MKPinAnnotationColorGreen;
pinView.animatesDrop = NO;
pinView.canShowCallout = YES;
}
else
pinView.annotation = annotation;
}

I am new to IPhone SDK Development i am trying to make an application with MapKit i have done the first bit i want to add multiple pins and annotation to the application but i am lost here.
Following is the code how can i add more pins to this code
-(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 = 26.438047;
region.center.longitude = 50.116422;
region.span.latitudeDelta=0.01f;
region.span.longitudeDelta=0.01f;
[mapView setRegion:region animated:YES];
[mapView setDelegate:self];
DisplayMap *ann = [[DisplayMap alloc] init];
ann.title = #"Corporate Office";
ann.subtitle =#"King Khalid Street";
ann.coordinate=region.center;
[mapView addAnnotation:ann];
}
-(MKAnnotationView *)mapView:(MKMapView *)mV viewForAnnotation:
(id <MKAnnotation>) annotation{
MKPinAnnotationView *pinView=nil;
if (annotation != mapView.userLocation) {
static NSString *defaultPinID = #"com.invasivecode.pin";
pinView = (MKPinAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:defaultPinID];
if (pinView ==nil) pinView = [[[MKPinAnnotationView alloc]
initWithAnnotation:annotation reuseIdentifier:defaultPinID] autorelease];
pinView.pinColor=MKPinAnnotationColorRed;
pinView.canShowCallout=YES;
pinView.animatesDrop=YES;
pinView.calloutOffset= CGPointMake(-5, 5);
}
else {
[mapView.userLocation setTitle:"I am here"];
}
return pinView;
}
you are on the right track already, just reuse your code to make multiple points.
for example :
DisplayMap *ann = [[DisplayMap alloc] init];
for( int i =1;i<=5;i++ ){
region.center.latitude = 26.438047+i;
region.center.longitude = 50.116422+i;
ann.title = [NSString stringWithFormat:#"title %d",i)];
ann.subtitle =[NSString stringWithFormat:#"subtitle %d",i)];
ann.image = [NSString stringWithFormat#"image_%d.png",i];
ann.coordinate=region.center;
[mapView addAnnotation:ann];
}
[ann release];
in result, will display 5 points in different coordinate. (with same name and subtitle).
Edited: show different pin image. you have to add new field as NSString *image to DisplayMap. and add your path image inside for loop.

[pinView release];
}

// if it's the user location, just return nil.

return nil;
if(annotation != map.userLocation)

{
counting++;
pinView = [[[MKAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:defaultPinID] autorelease];
for(DisplayMap* a in map.annotations)
{
if (annotation == a){
pinView.image =

}
}
