可以some1 plz引导我..下面是我自定义地图的方法..有人救我=（

 - (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation
{
//NSLog(@"welcome into the map view annotation");

for(int i = 0; i<[_annotation2 count]; i++){
    MyAnnotation* a = [_annotation2 objectAtIndex:i];
    MKPinAnnotationView *pinView=[[MKPinAnnotationView alloc] initWithAnnotation:a reuseIdentifier:[annotation title]];
    pinView.animatesDrop=YES;
    pinView.canShowCallout=YES;
    pinView.pinColor = MKPinAnnotationColorRed;
    return [pinView autorelease];

    UIButton* rightButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
    [rightButton setTitle:annotation.title forState:UIControlStateNormal];
    [rightButton addTarget:self
                    action:@selector(showDetails:)
          forControlEvents:UIControlEventTouchUpInside];
    pinView.rightCalloutAccessoryView = rightButton;

    UIImageView *profileIconView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"profile.png"]];
    pinView.leftCalloutAccessoryView = profileIconView;
    [profileIconView release];


    return pinView;

}

        MyAnnotation *b = [_annotation2 objectAtIndex:[_annotation2 count ]-1];

        MKPinAnnotationView *pinView2=[[MKPinAnnotationView alloc] initWithAnnotation:b reuseIdentifier:[annotation title]];
        pinView2.animatesDrop=YES;
        pinView2.canShowCallout=YES;
        pinView2.pinColor = MKPinAnnotationColorGreen;
        return [pinView2 autorelease];

        UIButton* rightButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
        [rightButton setTitle:annotation.title forState:UIControlStateNormal];
        [rightButton addTarget:self
                        action:@selector(showDetails:)
              forControlEvents:UIControlEventTouchUpInside];
        pinView2.rightCalloutAccessoryView = rightButton;

        UIImageView *profileIconView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"profile.png"]];
        pinView2.leftCalloutAccessoryView = profileIconView;
        [profileIconView release];


        return pinView2;

}

我尝试了这组新的代码，但它仍然无效=（

if(identifier == clinic) pin.color = red;
else if(identifier == other) pin.color = blue;
