My Custom MKAnnotationView isn't clickable - iphone

Question

i'm working on a custom annotationview that show a image of background, with inside a custom image.
I've based my code from this: Custom MKAnnotationView with frame,icon and image
And my actually code is:
else if ([annotation isKindOfClass:[ImagePin class]]){
static NSString *identifierImage = #"ImagePinLocation";
MKAnnotationView *annotationImageView = (MKAnnotationView *) [self.mapView dequeueReusableAnnotationViewWithIdentifier:identifierImage];
if(annotationImageView){
return annotationImageView;
}
else {
annotationImageView = [[MKAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:identifierImage];
annotationImageView.canShowCallout = YES;
annotationImageView.image = [UIImage imageNamed:#"image_bg_mappa"];
UIImage *frame = [UIImage imageNamed:#"image_bg_mappa"];
ImagePin *imagePinImage = annotation;
NSLog(#"%#", [NSString stringWithFormat:#"%#", imagePinImage.image]);
NSString *urlStringForImage = [NSString stringWithFormat:#"%#", imagePinImage.image];
NSURL *urlForImage = [NSURL URLWithString:urlStringForImage];
UIImageView *imageView = [[UIImageView alloc] init];
[imageView setImageWithURL:[NSURL URLWithString:[NSString stringWithFormat:#"%#", urlForImage]] placeholderImage:[UIImage imageNamed:#"avatar-placeholder.png"]];
UIGraphicsBeginImageContext(CGSizeMake(annotationImageView.image.size.width, annotationImageView.image.size.height));
[frame drawInRect:CGRectMake(0, 0, frame.size.width, frame.size.height)];
[imageView.image drawInRect:CGRectMake(2, 2, 48, 38)]; // the frame your inner image
annotationImageView.image = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
UIButton* rightButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
[rightButton addTarget:self action:#selector(writeSomething:) forControlEvents:UIControlEventTouchUpInside];
[rightButton setTitle:#"" forState:UIControlStateNormal];
annotationImageView.canShowCallout = YES;
annotationImageView.rightCalloutAccessoryView = rightButton;
annotationImageView.enabled = YES;
return annotationImageView;
}
}
And then i have two method:
(void)writeSomething {
}
(void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control {
}
But:
Not show my rightButton callout(not show also the button)
I prefer that when i click on the full image/annotation it call mapView annotationView method.
How i can do it ? Why when i click on annotation, it not call my calloutAccessoryControlTapped method ?
In this map i have also more different type of pin(mkpinannotation), and works fine(also the method calloutAccessoryControlTapped works fine with these pins).
Where is the problem ?
Thanks to all, and sorry for my bad english(I'm learning it).
EDIT: My full code for viewForAnnotation method: https://gist.github.com/anonymous/6224519e308d6bf56c4c
The MKPinAnnotation works fine.
EDIT:
This is my ImagePin.h
#import <Foundation/Foundation.h>
#import <MapKit/MapKit.h>
#interface ImagePin : NSObject <MKAnnotation>
- (id)initWithImage:(NSString*)image imagebeachId:(NSString*)imagebeachId coordinate:(CLLocationCoordinate2D)coordinate;
//- (MKMapItem*)mapItem;
#property (nonatomic, copy) NSString *imagebeachId;
#property (nonatomic, copy) NSString *image;
#property (nonatomic, assign) CLLocationCoordinate2D theCoordinate;
#end
And my ImagePin.m
#import "ImagePin.h"
#import <AddressBook/AddressBook.h>
#interface ImagePin ()
#end
#implementation ImagePin
#synthesize image = _image;
#synthesize imagebeachId = _imagebeachId;
#synthesize theCoordinate = _theCoordinate;
- (id)initWithImage:(NSString*)image imagebeachId:(NSString*)imagebeachId coordinate:(CLLocationCoordinate2D)coordinate {
if ((self = [super init])) {
//self.address = address;
self.image = image;
self.imagebeachId = imagebeachId;
self.theCoordinate = coordinate;
}
return self;
}
- (NSString *)title {
return #"";
}
- (NSString *)subtitle {
return _image;
}
- (CLLocationCoordinate2D)coordinate {
return _theCoordinate;
}
#end
EDIT:
This is where i add annotation:
- (void)imagePositions:(NSDictionary *)responseData {
for (id<MKAnnotation> annotation in self.mapView.annotations) {
if ([annotation isKindOfClass:[ImagePin class]]){
//[self.mapView removeAnnotation:annotation];
}
}
for (NSArray *row in responseData) {
NSString * imageBeachId = [row valueForKey:#"id"];
NSNumber * latitude = [row valueForKey:#"lat"];
NSNumber * longitude = [row valueForKey:#"lng"];
NSString * imageBeach = [row valueForKey:#"fb_photo_url"];
CLLocationCoordinate2D coordinate;
coordinate.latitude = latitude.doubleValue;
coordinate.longitude = longitude.doubleValue;
ImagePin *annotation = [[ImagePin alloc] initWithImage:imageBeach imagebeachId:imageBeachId coordinate:coordinate];
[self.mapView addAnnotation:annotation];
}
}

Answer 1

I have fixed all!
The problem is that title can't be empty(i was using #""... with a #"AAA works fine) and then for not show the callout i have done:
annotationView.canShowCallout = NO;
and implemented:
-(void)mapView:(MKMapView *)mapView didSelectAnnotationView:(MKAnnotationView *)view
{
//here you action
}
A BIG thanks to Anna(the solution is your)!

First checkout that you give the delegate to MapView or not , if not then give the delegate like bellow..
yourMapView.delegate = self;
Also in .h file define that delegate like bellow..
#interface ViewController : UIViewController<MKMapViewDelegate,MKAnnotation>{...
after check that this bellow method called when accessory tapped...
- (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control
{
NSLog(#"Do something ");
}
UPDATE:
Instead of Custom Button try to use it...
- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation {
NSLog(#"viewForAnnotation...");
static NSString *identifier = #"MyLocation";
if ([annotation isKindOfClass:[ImagePin class]]) {
MKAnnotationView *annotationView = (MKAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:identifier];
if (annotationView == nil)
{
annotationView = [[[MKAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:identifier] autorelease];
}
if (annotation == mapView.userLocation)
return nil;
annotationView.image = [UIImage imageNamed:#"yourImageName.png"];
annotationView.annotation = annotation;
annotationView.rightCalloutAccessoryView = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
annotationView.rightCalloutAccessoryView.tag = 101;
annotationView.canShowCallout = YES;
// annotationView.animatesDrop = YES;
return annotationView;
}
return nil;
}

For anyone else that stumbles upon this post while implementing a custom MKAnnotationView, the problem may also be that you have to explicitly set the frame of your view.
