I have a mapView to which I add annotations. The pin's callout have a button (rightCalloutAccessoryView). In order to be able to display various information when the button is pushed, i've subclassed uibutton and added a class called "Annotation".
@interface CustomButton : UIButton {
NSIndexPath *indexPath;
Annotation *mAnnotation;
}
@property (nonatomic, retain) NSIndexPath *indexPath;
@property (nonatomic, copy) Annotation *mAnnotation;
- (id) setAnnotation2:(Annotation *)annotation;
@end
Here is "Annotation":
@interface Annotation : NSObject <MKAnnotation> {
CLLocationCoordinate2D coordinate;
NSString *mPhotoID;
NSString *mPhotoUrl;
NSString *mPhotoName;
NSString *mOwner;
NSString *mAddress;
}
@property (nonatomic, assign) CLLocationCoordinate2D coordinate;
@property (nonatomic, copy) NSString *mPhotoID;
@property (nonatomic, copy) NSString *mPhotoUrl;
@property (nonatomic, copy) NSString *mPhotoName;
@property (nonatomic, copy) NSString *mOwner;
@property (nonatomic, copy) NSString *mAddress;
- (id) initWithCoordinates:(CLLocationCoordinate2D)coordinate;
- (id) setPhotoId:(NSString *)id url:(NSString *)url owner:(NSString *)owner address:(NSString *)address andName:(NSString *)name;
@end
I want to set the annotation property of the uibutton at - (MKAnnotationView *)mapView:(MKMapView *)pMapView viewForAnnotation:(id )annotation, in order to refer to it at the button push handler (-(IBAction) showDetails:(id)sender).
The problem is that I can't set the annotation property of the button. I get the following message at run time:
2010-04-27 08:15:11.781 HotLocations[487:207] *** -[UIButton setMAnnotation:]: unrecognized selector sent to instance 0x5063400

I appreciate the help.
Tzur.
