Issue with Map Annotation and MKMapView in iOS 4.2?

Question

I have a map view with pins that when the user selects a pin it goes to a detail screen for that pin. I also have a table view that when the user selects an item it goes to

Answer 1

If anyone would care to see what I am using now (and it is working) ...

- (MKPinAnnotationView *)mapView:(MKMapView *)eMapView viewForAnnotation:(id )annotation {

    MKPinAnnotationView *pinView = (MKPinAnnotationView *)[eMapView dequeueReusableAnnotationViewWithIdentifier:@"Pin"];

    if(pinView == nil) {

        pinView = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"Pin"];
        pinView.frame = CGRectMake(0, 0, 25, 25);

    } else {

        pinView.annotation = annotation;

    }   

    // Set up the Right callout
    UIButton *myDetailButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
    myDetailButton.frame = CGRectMake(0, 0, 23, 23);
    myDetailButton.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;
    myDetailButton.contentHorizontalAlignment = UIControlContentHorizontalAlignmentCenter;

    pinView.rightCalloutAccessoryView = myDetailButton;

    pinView.animatesDrop = YES;

    // Set to show a callout on the pin
    pinView.canShowCallout = YES;

    return pinView;
}

// Added this at the suggestion of aBitObvious on StackOverflow - 120810
- (void)mapView:(MKMapView *)eMapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control {

    if (view.annotation == eMapView.userLocation)
        return;

    if (self.showDetailView == nil) {

        DetailData *tmpViewController = [[DetailData alloc] initWithNibName:@"DetailData" bundle:nil];
        self.showDetailView = tmpViewController;
        [tmpViewController release];

    }

    buttonDetail = (MyCustomAnnotationClass *)view.annotation;

    NSMutableArray *tmpArray = [NSMutableArray arrayWithObjects: [buttonDetail getDataI], [buttonDetail getDataII], [buttonDetail getDataIII], [buttonDetail getDataIV], [buttonDetail getDataV], nil];

    self.showDetailView.eventData = [[NSMutableArray alloc] initWithArray:tmpArray copyItems:YES];

    [self.navigationController pushViewController:self.showDetailView animated:YES];

    [self.showDetailView.eventData release];

}

Thanks again!
