Setting action for custom UIButton subclass

I have been trying for a couple of days to find a way how to call action:selector on a custom button, derived from UIButton, which I want to associate with a pin annotation. The reason that I used a subclass is that I want to pass some data into this button object, in order to show another UIView displaying these data when the button is pressed.

The problem is that while executing, when I click on the pin annotation, it opens its button, and when I click on it, nothing happens. My showDetails: method is not called on receiving the touchupInside event as I set here:

[rightButton addTarget:self 
                action:@selector(showDetails:)
      forControlEvents:UIControlEventTouchUpInside];

My question is how to inherit the methods of UIButton, like addTarget:acti开发者_JAVA技巧on:forControlEvents:, buttonWithType:, etc., in order to use them in my subclass?

Here is the complete code concerning the problem:

- (MKAnnotationView *) mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>) annotation
{
    MKPinAnnotationView *annView=[[[MKPinAnnotationView alloc] 
        initWithAnnotation:annotation reuseIdentifier:@"MyPin"] autorelease];  
    annView.animatesDrop=FALSE;  
    annView.canShowCallout = YES;  
    [annView setSelected:YES]; 

    if ([[annotation title] isEqualToString:@"Current Location"]) {
        annView.pinColor = MKPinAnnotationColorRed;  
    }
    else {
        annView.pinColor = MKPinAnnotationColorPurple; 
    }

    annView.calloutOffset = CGPointMake(-5, 5);  

    PlaceMark *pm=(PlaceMark *)annotation;
    AddressItem *ai=[pm getData];

    //Another problem is that i cant set buttonWithType:UIButtonTypeDetailDisclosure cause it generate error cause it is a method of UIbutton superclass
    MyDetailButton* rightButton = [MyDetailButton buttonWithType:UIButtonTypeCustom];
    [rightButton setData:ai];

    [rightButton setTitle:annotation.title forState:UIControlStateNormal];

    [rightButton addTarget:self action:@selector(showDetails:) forControlEvents:UIControlEventTouchUpInside];

    annView.rightCalloutAccessoryView = rightButton;

    return annView;  
}

Thank you in advance. I hope that I have given a clear explanation of my problem.


I think you're on wrong way. To send action @selector your class need inherit from UIControl and not UIButton. Check out UIControl Class Reference I think the problem is here. Do not hesitate to tell me if I did not understand your question.
