ios: mapKit viewForAnnotation disappears popup Title from PIN? - ios

Question

I am trying to create draggable custom pin with Title popup with MapKit. but when I implement viewForAnnotation to make PIN appear as custom image, its disappears pop title as if I youch Pin on map it does not show titla popup,
while if I comments viewForAnnotation it works fine, but I want both things custom image and popup title when tap pin.
below is code
- (void)viewDidLoad
{
MKCoordinateRegion newRegion = MKCoordinateRegionMakeWithDistance(LocCoordinate, 20000, 20000);
DDAnnotation *point = [[DDAnnotation alloc] init];
[point setCoordinate:mapCenter];
[point setTitle:#"Where am I"];
[point setSubtitle:#"I am here"];
[self.mvTripMap addAnnotation:point];
[self.mvTripMap setRegion:newRegion animated:YES];
[super viewDidLoad];
}
-(MKAnnotationView *)mapView:(MKMapView *)MapView viewForAnnotation:(id<MKAnnotation>)annotation{
static NSString *cabAnnotationIdentifier=#"cabAnnotationIdentifier";
MKAnnotationView *annotationView=[MapView dequeueReusableAnnotationViewWithIdentifier:cabAnnotationIdentifier];
if(!annotationView){
annotationView=[[MKAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:cabAnnotationIdentifier];
annotationView.image=[UIImage imageNamed:#"start.png"];
annotationView.draggable = YES;
}
return annotationView;
}
DDAnnotation.h
#import <MapKit/MapKit.h>
#interface DDAnnotation : MKPlacemark {
CLLocationCoordinate2D coordinate_;
NSString *title_;
NSString *subtitle_;
}
// Re-declare MKAnnotation's readonly property 'coordinate' to readwrite.
#property (nonatomic, readwrite, assign) CLLocationCoordinate2D coordinate;
#property (nonatomic, retain) NSString *title;
#property (nonatomic, retain) NSString *subtitle;
#end
DDAnnotation.m
#import "DDAnnotation.h"
#implementation DDAnnotation
#synthesize coordinate = coordinate_;
#synthesize title = title_;
#synthesize subtitle = subtitle_;
- (id)initWithCoordinate:(CLLocationCoordinate2D)coordinate addressDictionary:(NSDictionary *)addressDictionary {
if ((self = [super initWithCoordinate:coordinate addressDictionary:addressDictionary])) {
self.coordinate = coordinate;
}
return self;
}
#end

Just put annotationView.canShowCallout= YES; and it will work
updated code
-(MKAnnotationView *)mapView:(MKMapView *)MapView viewForAnnotation:(id<MKAnnotation>)annotation{
static NSString *cabAnnotationIdentifier=#"cabAnnotationIdentifier";
MKAnnotationView *annotationView=[MapView dequeueReusableAnnotationViewWithIdentifier:cabAnnotationIdentifier];
if(!annotationView){
annotationView=[[MKAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:cabAnnotationIdentifier];
annotationView.image=[UIImage imageNamed:#"start.png"];
annotationView.draggable = YES;
annotationView.canShowCallout= YES;
}
return annotationView;
}
