将附件视图按钮添加到MKMapView调用注释？

Question

我最近遇到过这个网站,我一直试图在我的呼叫中添加一个按钮(来自图像).

网站上的代码示例工作正常,但当我尝试将相同的代码添加到我的项目时,我得不到相同的结果.

显然我错过了一些东西,但似乎无法解决这个问题!

这是我的注释代码:

- (MKAnnotationView *) mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>) annotation{
    MKPinAnnotationView *annView=[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"currentloc"];
    annView.pinColor = MKPinAnnotationColorGreen;

    UIButton *advertButton = [UIButton buttonWithType:UIButtonTypeCustom];
    advertButton.frame = CGRectMake(0, 0, 23, 23);
    advertButton.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;
    advertButton.contentHorizontalAlignment = UIControlContentHorizontalAlignmentCenter;

    [advertButton setImage:[UIImage imageNamed:@"button_right.png"] forState:UIControlStateNormal];
    [advertButton addTarget:self action:@selector(showLinks:) forControlEvents:UIControlEventTouchUpInside];

    annView.rightCalloutAccessoryView = advertButton;

    annView.animatesDrop=TRUE;
    annView.canShowCallout = YES;
    annView.calloutOffset = CGPointMake(-5, 5);
    return annView;
}

任何帮助,将不胜感激!:)

Answer 1

那家伙正在使用自定义图像来模仿细节披露.您可以非常轻松地获得标准的详细信息:

[UIButton buttonWithType:UIButtonTypeDetailDisclosure];

Answer 2

而不是像你在这里设置目标:

[advertButton addTarget:self action:@selector(showLinks:) forControlEvents:UIControlEventTouchUpInside];

您可以使用默认委托:

- (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control

很抱歉回答我自己的问题，但这可以通过将 MKMapView 的委托设置为 ViewController 来解决。唷，我花了一段时间才弄清楚，它是如此简单！
