Set custom image on pin in map in IOS - ios

Question

i have a map view in my view controller, when i make a pin on the desired place i give my own image despite of the default image , but when i run and check the map it always shows default pin in my map instead of my image that i have passed. My code is this,
-(MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id<MKAnnotation>)annotation{
MKAnnotationView *view=[self.mapView dequeueReusableAnnotationViewWithIdentifier:#"annoView"];
if (!view) {
view=[[MKAnnotationView alloc]initWithAnnotation:annotation reuseIdentifier:#"annoView"];
if ([annotation isKindOfClass:[MKUserLocation class]]) {
return nil;
}else{
view.image=[UIImage imageNamed:#"car_marker.png"];
view.canShowCallout=YES;
}
}
return view;
}
MapPin *pin=[[MapPin alloc]init];
pin.title=loc[#"name"];
pin.subtitle=nil;
pin.coordinate=annoCordinate;
[self.mapView addAnnotation:pin];
[self.mapView setCenterCoordinate:pin.coordinate animated:YES];

This is very easy to accomplish, you just need to subclass MKAnnotationView and add a custom image view to it. A good example can be found here.
In case the link dies, I have also included the code snippet below, please do show the OP some love though!
#interface TStickerAnnotationView : MKAnnotationView
#property(nonatomic) float stickerColor;
#end
#interface TStickerAnnotationView () {
UIImageView *_imageView;
TCircleView *_circleView;
}
#end
#implementation TStickerAnnotationView
- (id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self) {
// make sure the x and y of the CGRect are half it's
// width and height, so the callout shows when user clicks
// in the middle of the image
CGRect viewRect = CGRectMake(-30, -30, 60, 60);
TCircleView* circleView = [[TCircleView alloc] initWithFrame:viewRect];
_circleView = circleView;
[self addSubview:circleView];
UIImageView* imageView = [[UIImageView alloc] initWithFrame:viewRect];
// keeps the image dimensions correct
// so if you have a rectangle image, it will show up as a rectangle,
// instead of being resized into a square
imageView.contentMode = UIViewContentModeScaleAspectFit;
_imageView = imageView;
[self addSubview:imageView];
}
return self;
}
- (void)setImage:(UIImage *)image
{
// when an image is set for the annotation view,
// it actually adds the image to the image view
_imageView.image = image;
}
- (void)stickerColor:(float)color {
_circleView.green = color;
[_circleView setNeedsDisplay];
}
