我正在为地图实现自定义图钉,图片位于te项目的文件夹中但未显示。 也许(很可能)我做错了什么。
地图显示并显示引脚(默认红色引脚),但不显示自定义图像,也不显示UIButtonTypeDetailDisclosure
这是我正在使用的代码:
- (MKAnnotationView *)mapView:(MKMapView *)theMapView viewForAnnotation:(id<MKAnnotation>)annotation
{
// in case it's the user location, we already have an annotation, so just return nil
if ([annotation isKindOfClass:[MKUserLocation class]])
{
return nil;
}
static NSString *TheAnnotationIdentifier = @"theAnnotationIdentifier";
MKAnnotationView *shoppeAnnotationView =
[self.mapView dequeueReusableAnnotationViewWithIdentifier:TheAnnotationIdentifier];
if (shoppeAnnotationView == nil)
{
MKAnnotationView *annotationView = [[MKAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:TheAnnotationIdentifier];
annotationView.canShowCallout = YES;
annotationView.image = [UIImage imageNamed:@"pin.png"];
annotationView.rightCalloutAccessoryView = [ UIButton buttonWithType:UIButtonTypeDetailDisclosure ];
annotationView.opaque = NO;
return annotationView;
}
return nil;
}
任何提示?
谢谢!
