注释图像未设置为已编码

Question

我想知道这里有什么问题。注释显示默认的红色引脚。我已将图像文件复制到项目文件夹中并检查了名称。

- (MKAnnotationView *)mapView:(MKMapView *)aMapView
            viewForAnnotation:(id)ann {

    NSString *identifier = @"myPin";
    MKPinAnnotationView *annView = (MKPinAnnotationView *)
    [aMapView dequeueReusableAnnotationViewWithIdentifier:identifier];
    if (annView == nil) {
        annView= [[[MKPinAnnotationView alloc] initWithAnnotation:ann
                                               reuseIdentifier:identifier]
               autorelease];
    } else {
        annView.annotation = ann;
    }

    annView.rightCalloutAccessoryView = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
    UIImage *pinImage = [UIImage imageNamed:@"AnnotationIcon.png"];
    [annView setImage: pinImage];
    annView.enabled = YES;
    annView.animatesDrop=TRUE;
    annView.canShowCallout=YES;

    return annView;
}

Answer 1

经过一番研究，我发现MKPinAnnotationView - animatesDrop属性不能用于自定义图像。
