Question

我是iOS开发人员。我正在尝试显示自定义标注视图点击（图钉）。此标注视图包含两个按钮。我已经尝试使用下面给出的代码显示自定义标注视图。

       func mapView(mapView: MKMapView!, didSelectAnnotationView view: MKAnnotationView!) {

    var calloutSize:CGSize = CGSizeMake(200.0, 110.0)
    confirm = MKAnnotationView(frame: CGRect(x: -calloutSize.width/2, y: -calloutSize.height - 10, width: calloutSize.width, height:calloutSize.height))

    confirm!.backgroundColor = UIColor(white: 0.9, alpha: 1)
    confirm!.alpha = 0.7


    let button_Yes = UIButton(frame: CGRectMake(0, 0, 200, 54))
    button_Yes.backgroundColor = UIColor.purpleColor()
    button_Yes.setTitle("See listing detail", forState: UIControlState.Normal)
    button_Yes.addTarget(self, action:Selector( "checkout:"), forControlEvents: UIControlEvents.TouchUpInside)
    button_Yes.userInteractionEnabled = true
    button_Yes.tag = 1
    confirm!.addSubview(button_Yes)

    let button_No = UIButton(frame: CGRectMake(0,calloutSize.height / 2, 200, 54))

    button_No.backgroundColor = UIColor.purpleColor()
    button_No.setTitle("Get directions", forState: UIControlState.Normal)
    button_No.addTarget(self, action:Selector("checkin:"), forControlEvents: UIControlEvents.TouchUpInside)
    button_No.userInteractionEnabled = true
    button_No.tag = 2
    confirm!.addSubview(button_No)

    view.addSubview(confirm!)

}

func mapView(mapView: MKMapView!, didDeselectAnnotationView view: MKAnnotationView!) {

    confirm!.removeFromSuperview()
}

为此你需要创建MKAnnotationView和XIB的子类，使用此功能，您可以在

中返回标注的自定义视图

mapView(_:viewForAnnotation:)
