MKAnnotationView自定義圖像不顯示

Question

我想在地圖上添加自定義圖像，而不是常規圖釘。但它仍然是一個紅色的針......我錯過了什麼？

- (MKAnnotationView *) mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>) annotation{ 
    static NSString* AnnotationIdentifier = @"AnnotationIdentifier"; 
    MKPinAnnotationView *annView = [[MKPinAnnotationView alloc]  initWithAnnotation:annotation reuseIdentifier:AnnotationIdentifier]; 
    annView.animatesDrop = TRUE; 
    annView.image = [UIImage imageNamed:@"CustomPin.png"]; 
    return annView; 
}

MKMapView: Instead of Annotation Pin, a custom view

-(MKAnnotationView *)mapView:(MKMapView *)mV viewForAnnotation:(id <MKAnnotation>)annotation 
{ 
    MKAnnotationView *pinView = nil; 
    if(annotation != mapView.userLocation) 
    { 
     static NSString *defaultPinID = @"com.invasivecode.pin"; 
     pinView = (MKAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:defaultPinID]; 
     if (pinView == nil) 
      pinView = [[MKAnnotationView alloc] 
             initWithAnnotation:annotation reuseIdentifier:defaultPinID]; 

     //pinView.pinColor = MKPinAnnotationColorGreen; 
     pinView.canShowCallout = YES; 
     //pinView.animatesDrop = YES; 
     pinView.image = [UIImage imageNamed:@"pinks.jpg"]; //as suggested by Squatch 
    } 
    else { 
     [mapView.userLocation setTitle:@"I am here"]; 
    } 
    return pinView; 
}

我發現它有助於查看蘋果文檔並下載示例代碼。

他們正在實施自己的地圖自定義註釋。

嗨只是刪除您一行代碼... annView.animatesDrop = TRUE;

次還代碼 -

-(MKAnnotationView *) mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>) annotation{ 
    static NSString* AnnotationIdentifier = @"AnnotationIdentifier"; 
    MKPinAnnotationView *annView = [[MKPinAnnotationView alloc]  initWithAnnotation:annotation reuseIdentifier:AnnotationIdentifier]; 
    annView.image = [UIImage imageNamed:@"CustomPin.png"]; 
    return annView; 
}
