Mapbox - calloutAccessoryController已調整

Question

我遇到了與我的calloutAccessoryControllerTapped問題。在我的標註中，我有兩個按鈕 - 每個按鈕都會在我的地圖視圖中繼續顯示模式彈出。在我的segue工作的那一刻，但兩個按鈕繼續到相同的彈出。我需要能夠區分按鈕和他們的segue。

這可能嗎？我用Google搜索這個問題，很多答案，似乎可以用下面這行代碼下面

if (control == view.leftCalloutAccessoryView) { 

但是暗示，這是來了一個錯誤「類型的值‘的UIView’沒有成員‘leftCalloutAccessoryView’。我真的很不勝感激，如果有人可以幫助我解決這個問題，很抱歉，如果我沒有解釋清楚這個問題，我已經這樣做了我最好的程度

下面是我的代碼：

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 

} 


}

要簡單的（變化碼根據您的需要）這可用於區分左側和右側標註附件控件。

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") 
    } 
}
