解决方法

        如果我理解正确，您想添加一个显示按钮，该按钮将允许您使用有关当前引脚注释的信息来呈现新视图。要获得披露按钮，您只需实现以下代码： 
- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation {
    MKPinAnnotationView *pinView = (MKPinAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:@\"pinView\"];
    if (!pinView) {
        pinView = [[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@\"pinView\"] autorelease];
        pinView.pinColor = MKPinAnnotationColorRed;
        pinView.animatesDrop = YES;
        pinView.canShowCallout = YES;

        UIButton *rightButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
        pinView.rightCalloutAccessoryView = rightButton;
    } else {
        pinView.annotation = annotation;
    }
    return pinView;
}
现在，当您点击mapView上的图钉时，显示的按钮将显示在显示的视图中。然后，您将需要使用以下方法告诉应用程序，当按下披露按钮时该怎么做。 
- (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control
在这种方法中，您可以显示一个弹出窗口或模式窗口，或者按一个视图或执行任何有关当前位置信息的操作。您也不需要为每个对象创建一个新的笔尖。最简单的方法是在该视图控制器中合成诸如
phoneNumber
和
website
之类的值。然后，在显示视图的最后一种方法中，根据需要传递值。例如， 
NewView *vc = [[NewView alloc] initWithNibName:@\"NewView\" bundle:nil];
vc.phoneNumber = // the phone number of this location;
vc.website = // the website;
呈现视图之前，依此类推。我希望这有帮助 编辑：要摆脱该错误，对于您合成的所有内容，必须在标头中声明。所以你有 
@interface FirstViewController : UIViewController {
    IBOutlet MKMapView  *mapView;
    //stores go here!
    //declare store names as Company *cityState
    AddressAnnotation *chiliAuburnAlabama;
    AddressAnnotation *tuttifruttiHomewoodAlabama;

    NSString *website;
    // the rest of your synthesized attributes you want in the view controller;
}
-(IBAction) updateLocation;
-(IBAction) setMap:(id)sender;
-(IBAction) showPin;

@property (nonatomic,retain) NSString *website;
// This is the property that will get rid of your error and you should do it to any other attributes you want to pass into the controller;
@end
如果在其中使用注释标题，也将需要它。它告诉代码的那一部分，它应该期望向它发送一些字符串，并且它将知道如何处理它。 至于调用GoToMap方法，则应在创建它时为MoreInfo类设置一个委托。因此，在MoreInfo标头中，您将拥有其他所有功能 
@interface MoreInfo .... {
    id delegate;
    // everything else;
}
@property (nonatomic,assign) id delegate;
// your methods and other properties;
@end
然后，当您在视图控制器中创建它时， 
MoreInfo *moreInfoView = [[MoreInfo alloc] initWithNibName:@\"MoreInfo\" bundle:nil];
moreInfoView.title = view.annotation.title ;
moreInfoView.delegate = self;
// this assigns the current view controller as its delegate;
//moreInfoView.getDirections = [NSURL URLWithString:[NSString stringWithFormat: @\"http://maps.google.com/maps?q=%@@%1.6f,%1.6f&z=10\",view.annotation.coordinate.latitude,view.annotation.coordinate.longitude]];
moreInfoView.getWebsite = view.annotation.website;
[self.navigationController pushViewController:moreInfoView animated:YES];
最后，当您想从MoreInfo调用GoToWebsite时，可以调用 
[self.delegate GoToWebsite];
当然，这是假设该方法在您的第一个视图控制器中（我可以发誓是这样，但是突然找不到）。 但这基本上就是您要做的事情
