custom annotation is not appearing without setting image - ios

Question

I am trying to create custom annotation as each annotation save some data which i need to show on tap of pin. But i need to show default ios pin image. Everything is working fine but pin will only show when i set any image. without setting image it is not showing default ios pin. My code is
CustomAnnotation.h file
#interface CustomAnnotation : NSObject<MKAnnotation>
#property(nonatomic,strong)NSString *title;
#property(nonatomic,strong)NSString *subTitle;
#property(nonatomic)CLLocationCoordinate2D coordinate;
#property(nonatomic,strong) UserDevice *userData;
-(instancetype)initWithUserData:(UserDevice *)userData;
on mapViewC.h
-(void)addMarkersOnMap{
for (UserDevice* userDevice in markersArray) {
CustomAnnotation *point = [[CustomAnnotation alloc]initWithUserData:userDevice];
point.coordinate = CLLocationCoordinate2DMake(userDevice.latitude, userDevice.longitude);
point.userData = userDevice;
point.title = #"dszf";
[mapview addAnnotation:point];
MKMapRect mapRect = [self getZoomingRectOnMap:mapview toFitAllOverlays:YES andAnnotations:YES includeUserLocation:NO];
[mapview setVisibleMapRect:mapRect edgePadding:UIEdgeInsetsMake(10.0, 10.0, 10.0, 10.0) animated:YES];
}
}
#pragma mark - MKMapView Delegate methods
- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id<MKAnnotation>)annotation {
if ([annotation isKindOfClass:[MKUserLocation class]]) {
return nil;
}
if ([annotation isKindOfClass:[CustomAnnotation class]]) {
CustomAnnotation *customAnnotation = annotation;
MKAnnotationView *customAnnotationView = (MKAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:#"annotationViewID"];
if (customAnnotationView == nil){
customAnnotationView = [[MKAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:#"annotationViewID"];
}
// customAnnotationView.image = [UIImage imageNamed:#"pin-1"];
customAnnotationView.canShowCallout = true;
customAnnotationView.annotation = customAnnotation;
return customAnnotationView;
}
return nil;
}

Answer 1

Instead of CustomAnnotationView use MKPinAnnotationView in your viewForAnnotation MKMapViewDelegate method
- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id<MKAnnotation>)annotation {
if ([annotation isKindOfClass:[MKUserLocation class]]) {
return nil;
}
if ([annotation isKindOfClass:[CustomAnnotation class]]) {
CustomAnnotation *customAnnotation = annotation;
MKPinAnnotationView *customAnnotationView = (MKPinAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:#"annotationViewID"];
if (customAnnotationView == nil){
customAnnotationView = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:#"annotationViewID"];
}
// customAnnotationView.image = [UIImage imageNamed:#"pin-1"];
customAnnotationView.canShowCallout = true;
customAnnotationView.annotation = customAnnotation;
return customAnnotationView;
}
return nil;
}
Hope this helps

CustomAnnotation *customAnnotation = annotation;
NSString *annotationIdentifier = #"PinViewAnnotation";
MKPinAnnotationView *pinView = (MKPinAnnotationView*)[mapView dequeueReusableAnnotationViewWithIdentifier: annotationIdentifier];
if (pinView ==nil) {
pinView = [[MKPinAnnotationView alloc]initWithAnnotation: customAnnotation reuseIdentifier: annotationIdentifier];
}
pinView.pinColor = MKPinAnnotationColorGreen; // change color
pinView.canShowCallout = YES;
pinView.enabled = YES;
mapView selectAnnotation:pinView animated:YES];
