任何人都可以使用MapKit框架提供在OS 4.0中实现可拖动引脚的任何示例代码/指令吗?

肯定的事情伙计(是的,我在跟自己说话),

在您的自定义注释中添加:

@property (nonatomic, readwrite, assign) CLLocationCoordinate2D coordinate;

这满足了实现setCoordinate的要求,如http://developer.apple.com/iphone/library/documentation/MapKit/Reference/MKAnnotationView_Class/Reference/Reference.html#//apple_ref/occ/instp/MKAnnotationView/draggable中所述.

在MapView委托中添加:

- (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)annotationView didChangeDragState:(MKAnnotationViewDragState)newState fromOldState:(MKAnnotationViewDragState)oldState 
{
//..Whatever you want to happen when the dragging starts or stops
}

并在您的AnnotationView集中可拖动为true,例如:

customAnnotationView.draggable      = YES;

我认为这就是我为使其发挥作用所做的一切.告诉我你是否有麻烦.
