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];
}

如果您愿意，我单击“更多”按钮按下每个引脚的引脚已经处于不同的视图中我甚至不知道怎么做这个。无论当前状态如何，请选择任何带有相同详细信息页面的引脚例如，按下按钮是大本钟，webview 威斯敏斯特桥被迫来到textview 我要实现。请注意，我可以使用xcode 4.2版本和故事板。以下几天我会为此感谢你，谢谢你。

Answer 1

// 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]);
    }
}

引脚标注视图的详细视图想要给出不同的值
