我有一个detailDisclousurea 的标注上的按钮MKAnnotation。当按下此按钮时，我需要调用一个传递标识参数的方法annotation那叫它。怎么可能呢？
这是我的注释视图：
- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation
{
if ([annotation isKindOfClass:[Annotation class]])
{
static NSString* identifier = @"identifier";
MKPinAnnotationView* pinView = (MKPinAnnotationView*)[mapView dequeueReusableAnnotationViewWithIdentifier:identifier];
if (pinView == nil)
{
pinView = [[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:identifier]autorelease];
}
Annotation *antt = annotation;
pinView.canShowCallout = YES;
pinView.draggable = YES;
UIButton* detailButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
[detailButton performSelector:@selector(goToViewWithAnnotation:) withObject:antt];
pinView.rightCalloutAccessoryView = detailButton;
return pinView;
}
else
{
return nil;
}
}
这是应该使用参数调用的方法：
-(void)goToViewWithAnnotation:(Annotation *)annotation
{
NextViewController *nextView = [[NextViewController alloc]initWithNibName:@"NextViewController" bundle:nil];
nextView.id = annotation.id;
[self.navigationController nextView animated:YES];
}
你可以通过任何NSInteger通过tag的财产UIButton only.
