当我尝试拖动时，自定义MKAnnotation图像会恢复为默认值 [英] Custom MKAnnotation Image goes back to default when I attempt to drag

问题描述

我有一堆不需要拖动的MKA注释.我用[pin setDraggable:NO]设置.当我触摸注释并(偶然)拖出注释时遇到问题，它会立即失去其自定义图像并变回默认的红色图钉.如何防止这种情况发生?

I've got a bunch of MKAnnotations that don't need dragging. I set this by [pin setDraggable:NO]. I'm having an issue when I touch the annotation and (accidentally) drag off an annotation, it instantly looses it's custom image and changes back to the default red pin. How do I prevent this from happening?

推荐答案

在viewForAnnotation委托方法中， 确保将视图创建为MKAnnotationView ，而不是MKPinAnnotationView (这是MKAnnotationView的子类，该子类会自动提供固定图片).

In the viewForAnnotation delegate method, make sure the view is created as an MKAnnotationView and not an MKPinAnnotationView (which is a subclass of MKAnnotationView that automatically provides a pin image).
