How to add UIImage in MKMapView in iPhone? - iphone

Question

I want to add a UIImage in MKMapview.
i.e.: One a particular location, I want to add an image called "apple.jpg".
I don't know how to do that.
As I have already added a draggable pin as an annotation. But I don't know if I can add multiple images or not.

Answer 1

For add image as a Part of MKMapView see this Tutorial...
i.ndigo mkmapview
and for add Image as a Pin on MapView then use this bellow code...
MKAnnotationView *annotationView = [[[MKAnnotationView alloc] init];
annotationView.image = [UIImage imageNamed:#"apple.png"];
annotationView.annotation = annotation;
annotationView.rightCalloutAccessoryView = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
annotationView.rightCalloutAccessoryView.tag = 101;
annotationView.canShowCallout = YES;
[yourMapView addAnnotation:annotationView];

Answer 2

as #Kassem Bagher mentions, you need to create custom MKAnnotationView , check whatever tutorial (example)

Answer 3

Your image must be in png format see the code below.
- (MKAnnotationView *) mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>) annotation
{
MKPinAnnotationView *pinView = (MKPinAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:#"pinView"];
if (!pinView) {
pinView = [[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:#"pinView"] autorelease];
pinView.image = [UIImage imageNamed:#"apple.png"];
pinView.canShowCallout = YES;
}
}

Answer 4

This is working code and i already done with below code no necessory image is .png , .jpg or .gif its any formate you can use it
- (MKAnnotationView *)mapView:(MKMapView *)map viewForAnnotation:(id <MKAnnotation>)annotation
{
MKPinAnnotationView *pinAnnotation = nil;
NSString *defaultPinID = #"myPin";
pinAnnotation = (MKPinAnnotationView *)[mapview dequeueReusableAnnotationViewWithIdentifier:defaultPinID];
if ( pinAnnotation == nil )
pinAnnotation = [[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:defaultPinID] autorelease];
pinAnnotation.image = [UIImage imageNamed:#"marker_postoffice.png"];
pinAnnotation.annotation = annotation;
pinAnnotation.canShowCallout = YES;
UIButton *infoButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
[infoButton addTarget:self action:#selector(showDetails)forControlEvents:UIControlEventTouchUpInside];
pinAnnotation.rightCalloutAccessoryView = infoButton;
// now you can set diff image by [annotation title] you can set diff image with if else condition like below code
if([[annotation title] isEqualToString:objAppDelegate.OfficePinTitle])
{
pinAnnotation.image = [UIImage imageNamed:#"marker_postoffice.png"];
pinAnnotation.annotation = annotation;
pinAnnotation.canShowCallout = YES;
UIButton *infoButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
infoButton addTarget:self
action:#selector(showDetails)forControlEvents:UIControlEventTouchUpInside];
pinAnnotation.rightCalloutAccessoryView = infoButton;
}
else
{
pinAnnotation.image = [UIImage imageNamed:#"marker_red_postoffice.png"];
pinAnnotation.canShowCallout = YES;
UIButton *infoButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
[infoButton addTarget:self action:#selector(showDetails)forControlEvents:UIControlEventTouchUpInside];
pinAnnotation.rightCalloutAccessoryView = infoButton;
}
}
