推荐答案

您可能正在添加类似这样的蓝色按钮

You are probably adding the blue button something like this

- (MKAnnotationView *) mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>) annotation{
MKPinAnnotationView *annView=(MKPinAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:@"annViewIdentifier"];

    if (annView == nil) {
        annView = [[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"annViewIdentifier"] autorelease];
    }
UIButton *infoDefaultButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];

        [infoDefaultButton addTarget:self
                       action:@selector(showDetails:)
             forControlEvents:UIControlEventTouchUpInside];
        annView.rightCalloutAccessoryView = infoDefaultButton;

}

如果需要任何自定义按钮，则可以添加UIButtonTypeCustom而不是UIButtonTypeDetailDisclosure并设置其框架.

if you want any custom button, then you can add UIButtonTypeCustom instead of UIButtonTypeDetailDisclosure and set its frame.
