MKAnnotationView標註中的倒置文本

Question

我正在使用此代碼在Swift中創建一個簡單的MKAnnotationView標註。

let local_parking = CustomAnnotation() 
    local_parking.coordinate = parking.coordinate.coordinate 
    local_parking.title = "Street name" 
    local_parking.subtitle = "Click on the button to get there" 
    self.mapView.addAnnotation(local_parking) 
} 
. 
. 
. 
func mapView(mapView:MKMapView, viewForAnnotation annotation:MKAnnotation) -> MKAnnotation? { 
    ... 
    let customAnnotation = annotation as! CustomAnnotation 
    annotationView?.canShowCallout = true 

    let accessoryButton : UIButton = UIButton(type: .DetailDisclosure) 
    annotationView!.rightCalloutAccessoryView = accessoryButton 

    return annotationView 
} 

我不知道爲什麼一些標註出現倒置，其他顯示正常。
