iOS谷歌地图标记拖动事件

我正在使用谷歌地图SDK构建一个iOS应用程序。当用户长按坐标时，我可以在地图上添加一些标记。我的问题是，当我试图拖动一个标记时，diiLongPressAtCoordinate会在DidBegindRagingMarker之前触发，因此还会添加一个新的标记

-(void)mapView:(GMSMapView *)mapView didBeginDraggingMarker:(GMSMarker *)marker{
        NSLog(@"begin dragging marker");
    }
    - (void)mapView:(GMSMapView *)mapView didLongPressAtCoordinate (CLLocationCoordinate2D)coordinate{
        NSLog(@"did long press at mapview");
    //when user didLongPressAtCoordinate I add a new marker on the map.
    // I want to prevent the execution of this code before the didBeginDraggingMarker method
    }

---

我通过创建一个名为IsDraging的布尔属性并根据是否拖动标记更改其值来解决这个问题

- (void)mapView:(GMSMapView *)mapView didBeginDraggingMarker:(GMSMarker *)marker
{
    self.isDragging = YES;
}

- (void)mapView:(GMSMapView *)mapView didEndDraggingMarker:(GMSMarker *)marker
{
    self.isDragging = NO;
}

然后，我验证是否在检测到长按时拖动标记：

- (void)mapView:(GMSMapView *)mapView didLongPressAtCoordinate:(CLLocationCoordinate2D)coordinate
{
    if (self.isDragging) {

        return;
    }

    NSLog(@"Long press detected");
}
