Mapbox - calloutAccessoryController已调整

Question

我遇到了与我的calloutAccessoryControllerTapped问题。在我的标注中，我有两个按钮 - 每个按钮都会在我的地图视图中继续显示模式弹出。在我的segue工作的那一刻，但两个按钮继续到相同的弹出。我需要能够区分按钮和他们的segue。

这可能吗？我用Google搜索这个问题，很多答案，似乎可以用下面这行代码下面

if (control == view.leftCalloutAccessoryView) { 

但是暗示，这是来了一个错误“类型的值‘的UIView’没有成员‘leftCalloutAccessoryView’。我真的很不胜感激，如果有人可以帮助我解决这个问题，很抱歉，如果我没有解释清楚这个问题，我已经这样做了我最好的程度

下面是我的代码：

func mapView(_ mapView: MGLMapView, annotationCanShowCallout annotation: MGLAnnotation) -> Bool { 

    return true 


} 


func mapView(_ mapView: MGLMapView, annotation: MGLAnnotation, calloutAccessoryControlTapped control: UIControl) { 


    self.performSegue(withIdentifier: "Show", sender: view) 

} 

func mapView(_ mapView: MGLMapView, rightCalloutAccessoryViewFor annotation: MGLAnnotation) -> UIView? { 

    guard let skateAnnotation = annotation as? SkateAnnotation else { return nil } 

    if skateAnnotation.canEdit { 
     return UIButton(type: .detailDisclosure) 
    } 

    return nil 


} 

func mapView(_ mapView: MGLMapView, leftCalloutAccessoryViewFor annotation: MGLAnnotation) -> UIView? { 

    return UIButton(type: .contactAdd) 


} 



func mapView(_ mapView: MGLMapView, imageFor annotation: MGLAnnotation) -> MGLAnnotationImage? { 

    return nil 

} 


}

要简单的（变化码根据您的需要）这可用于区分左侧和右侧标注附件控件。

func mapView(_ mapView: MGLMapView, leftCalloutAccessoryViewFor annotation: MGLAnnotation) -> UIView? { 
    let button = UIButton(type: .detailDisclosure) 
    button.tag = 100 
    return button 
} 

func mapView(_ mapView: MGLMapView, rightCalloutAccessoryViewFor annotation: MGLAnnotation) -> UIView? { 
    let button = UIButton(type: .detailDisclosure) 
    button.tag = 101 
    return button 
} 

func mapView(_ mapView: MGLMapView, annotation: MGLAnnotation, calloutAccessoryControlTapped control: UIControl) { 
    // Hide the callout view. 
    mapView.deselectAnnotation(annotation, animated: false) 

    if control.tag == 100 { 
     print("left") 
    } else if control.tag == 101 { 
     print("right") 
    } 
}
