推荐答案

当您在annotationView:view内部的标注中performSegueWithIdentifier:sender时，发件人可以是view.annotation属性，该属性唯一地标识用户刚刚点击的标注

When you performSegueWithIdentifier:sender from a callout inside annotationView:view, the sender can be the view.annotation property, which uniquely identifies the callout that the user just tapped.
