端号详图索引视图的详细视图希望提供不同的值

Question

这是我的代码

@implementation AnnotationViewController
@synthesize mapView;
-(void)viewDidLoad {
    [super viewDidLoad];
    [mapView setMapType:MKMapTypeStandard];
    [mapView setZoomEnabled:YES];
    [mapView setScrollEnabled:YES];
    [mapView setDelegate:self];
    MKCoordinateRegion bigBen = { {0.0, 0.0} , {0.0, 0.0} };
    bigBen.center.latitude = 51.50063;
    bigBen.center.longitude = -0.124629;
    bigBen.span.longitudeDelta = 0.02f;
    bigBen.span.latitudeDelta = 0.02f;
    [mapView setRegion:bigBen animated:YES];
    Annotation *ann1 = [[Annotation alloc] init];
    ann1.title = @"Big Ben";
    ann1.subtitle = @"Your subtitle";
    ann1.coordinate = bigBen.center;
    [mapView addAnnotation: ann1];
    MKCoordinateRegion Bridge = { {0.0, 0.0} , {0.0, 0.0} };
    Bridge.center.latitude = 51.500809;
    Bridge.center.longitude = -0.120914;
    Bridge.span.longitudeDelta = 0.02f;
    Bridge.span.latitudeDelta = 0.02f;
    [mapView setRegion:Bridge animated:YES];
    Annotation *ann2 = [[Annotation alloc] init];
    ann2.title = @"Westminster Bridge";
    ann2.subtitle = @"Your subtitle";
    ann2.coordinate = Bridge.center;
    [mapView addAnnotation:ann2];
}
-(MKAnnotationView *) mapView:(MKMapView *)mapView viewForAnnotation:(id<MKAnnotation>)annotation {

    MKPinAnnotationView *MyPin=[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"current"];
    MyPin.pinColor = MKPinAnnotationColorGreen;
    UIButton *advertButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
    [advertButton addTarget:self action:@selector(button:) forControlEvents:UIControlEventTouchUpInside];
    MyPin.rightCalloutAccessoryView = advertButton;
    MyPin.draggable = NO;
    MyPin.highlighted = YES;
    MyPin.animatesDrop=TRUE;
    MyPin.canShowCallout = YES;

    return MyPin;
}
-(void)button:(id)sender {
    NSLog(@"Button action");
    [self performSegueWithIdentifier:@"detail" sender:sender];
    [self performSegueWithIdentifier:@"under" sender:sender];
}

我点击了"更多"按钮，如果你想的话，每个引脚已经在不同的视图中了我甚至不知道该怎么做。无论当前状态如何，选择任何带有相同详细信息页面的引脚例如是大本钟出来的按钮被按下了，webview西敏寺大桥被要求进入文本视图我想做。注意，我可以使用xcode 4.2版本和故事板。给我几天时间，我会感谢你的。

// You can probably use the property selectedAnnotations in MKMapView
// You might want to consider adding some more error checking
-(void)button:(id)sender {
    if ([mapView.selectedAnnotations count] >= 1) {
        NSLog(@"%@title = %@", [[mapView.selectedAnnotations objectAtIndex:0] title]);
    }
}
