如何在MKPinAnnotationView中實現多個標註

這是我的第一個關於堆棧溢出的問題，也是我的新iOS開發。我正在爲我的學校開發地圖應用程序。我的學校有25座建築。我的地圖中有25個MKPinAnnotationViews。如何在MKPinAnnotationView中實現多個標註

- (MKAnnotationView *)mapView:(MKMapView *)theMapView viewForAnnotation:(id <MKAnnotation>)annotation 
{ 
// if it's the user location, just return nil. 
if ([annotation isKindOfClass:[MKUserLocation class]]) 
    return nil; 

// handle our two custom annotations 
// 
if ([annotation isKindOfClass:[SchureAnnotation class]]) // for Harry Schure Hall 
{ 
    // try to dequeue an existing pin view first 
    static NSString* SchureAnnotationIdentifier = @"schureAnnotationIdentifier"; 
    MKPinAnnotationView* pinView = (MKPinAnnotationView *) 
    [mapView dequeueReusableAnnotationViewWithIdentifier:SchureAnnotationIdentifier]; 
    if (!pinView) 
    { 
     // if an existing pin view was not available, create one 
     MKPinAnnotationView* customPinView = [[[MKPinAnnotationView alloc] 
               initWithAnnotation:annotation reuseIdentifier:SchureAnnotationIdentifier] autorelease]; 
     customPinView.pinColor = MKPinAnnotationColorPurple; 
     customPinView.animatesDrop = YES; 
     customPinView.canShowCallout = YES; 

     // add a detail disclosure button to the callout which will open a new view controller page 
     // 
     // note: you can assign a specific call out accessory view, or as MKMapViewDelegate you can implement: 
     // - (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control; 
     // 
     UIButton* rightButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure]; 
     [rightButton addTarget:self 
         action:@selector(showDetails:) 
       forControlEvents:UIControlEventTouchUpInside]; 
     customPinView.rightCalloutAccessoryView = rightButton; 

     return customPinView; 
    } 
    else 
    { 
     pinView.annotation = annotation; 
    } 
    return pinView; 
} 
else if ([annotation isKindOfClass:[SaltenAnnotation class]]) // for Salten Hall 
{ 
    // try to dequeue an existing pin view first 
    static NSString* SaltenAnnotationIdentifier = @"saltenAnnotationIdentifier"; 
    MKPinAnnotationView* pinView = (MKPinAnnotationView *) 
    [mapView dequeueReusableAnnotationViewWithIdentifier:SaltenAnnotationIdentifier]; 
    if (!pinView) 
    { 
     // if an existing pin view was not available, create one 
     MKPinAnnotationView* customPinView = [[[MKPinAnnotationView alloc] 
               initWithAnnotation:annotation reuseIdentifier:SaltenAnnotationIdentifier] autorelease]; 
..........

我想放一個不同的標註來顯示其每個引腳的信息。我打電話的功能showDetails：它看起來像這樣

- (void)showDetails:(id)sender 
{ 
// the detail view does not want a toolbar so hide it 
[self.navigationController setToolbarHidden:YES animated:NO]; 

[self.navigationController pushViewController:detailViewController animated:YES]; 
}

中序顯示每個建築物的信息，我需要寫25個視圖控制器？或者有無法使用一個視圖控制器？如果我點擊註解視圖的右鍵，它必須顯示它的信息（圖片，文字）。如果我點擊另一個註釋，它必須通過替換舊信息來顯示其信息。

任何幫助非常感謝。謝謝， Pradeep。

不要使用 [rightButton addTarget:self action:@selector(showDetails:) forControlEvents:UIControlEventTouchUpInside];

更改爲

[rightButton addTarget:self action:nil forControlEvents:UIControlEventTouchUpInside];

然後：

第1步：

- (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control { [self performSegueWithIdentifier:@"TCServiceStationDetailFromMap" sender:view]; }

步驟2：

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender

{

如果（[segue.identifier isEqualToString：@ 「TCServiceStationDetailFromMap」]）{

MKAnnotationView *view = sender; 
    TSPlaceMark *detailPlaceMark = (TSPlaceMark *)view.annotation; 
    //... 
    //so that you can get the different MKAnnotationView 
}

}
