【中文标题】向 MKPointAnnotation 添加按钮？

【英文标题】：Adding a button to MKPointAnnotation?

【问题描述】：

我只写了几行代码，但在尝试向我的注释点添加详细信息按钮时卡住了，我不知道怎么做。有谁知道这是怎么做到的吗？下图显示了我想要实现的目标。谢谢！

我试图在我的注释中获得圆圈中的大 i。

现在我只有一个带有标题和副标题的注释，如下所示。

另外，如果你知道，当用户点击圆圈中的 i 时，我如何将他们带到新的转场？

感谢您的帮助。

【问题讨论】：

查看这个***.com/questions/28225296/…

故事板中地图视图的代理出口是否连接到视图控制器？如果没有，则不会调用 viewForAnnotation 等委托方法。

Johnny，当你说调用 viewForAnnotation 方法时，你的意思是这样的吗？ mapView(mapView, viewForAnnotation: annotation) 另外，我应该把它放在哪里，就在评论下面 // 为了添加按钮，我们必须使用一个名为 viewForAnnotation 的方法？安娜，你是什么意思地图视图代表出口？我只是控制从情节提要上的 MKMapView 单击到我的视图控制器并将其添加为插座。

@emaadali，请参阅此问题中的图片：***.com/questions/9056535/…。委托出口（圆形图标）应该连接（填充）到视图控制器——不仅仅是 mapView 出口。此外，您不调用 viewForAnnotation。地图视图本身会调用它（但前提是它的委托已设置）。

【参考方案1】：

我无权访问您的第二个图片网址，但我假设您正在查看以下内容。如果没有，请在下面发表评论。

  func mapView(mapView: MKMapView!, annotationView: MKAnnotationView, calloutAccessoryControlTapped control: UIControl) 

        if control == annotationView.rightCalloutAccessoryView 
            performSegueWithIdentifier("Detail", sender: self)

嘿，第二张图片在这里：imgur.com/L3VMe5l 问题主要是我还没有注释中的披露按钮。我只是无法显示按钮。
