ios - 设置手势委托(delegate)时无法选择 map 对象

Question

这是与 相关的问题。这里 iOS HybridPlus SDK .

如果与类 NMAMapView 的 mapView 进行了任何交互和 NMAMapViewDelegate和 NMAMapGestureDelegate两者都设置然后只有 NMAMapGestureDelegate 的方法正在被调用。

例如:

如果点击 map 上的对象，则 - mapView:didReceiveTapAtLocation:被调用并 - mapView:didSelectObjects:不会被调用!

而在android中情况并非如此。在 android 中，如果一个对象被点击并且两个代表都被设置，那么上面提到的两个方法都会被调用。

问题:在 iOS 中解决这个问题的方法是什么？

Answer 1

从 得到这个答案HERE 开发支持 .

The mapView:didSelectObjects: is not getting called, because they are overriding the default tap handler by implementing mapView:didReceiveTapAtLocation in their NMAMapGestureDelegate. Because this is a protocol, they cannot call mapView:didReceiveTapAtLocation of the super class to run the default implementation, after they perform operation they need. However objects passed to mapView:didSelectObjects: are retrieved in a standard way, which is available to the customer, therefore they can mimic the default implementation, for example:

- (void)mapView:(NMAMapView *)mapView didReceiveTapAtLocation:(CGPoint)location  {

    NSLog(@"didReceiveTapAtLocation: %fx%f", location.x, location.y); 
    if ([mapView.delegate respondsToSelector:@selector(mapView:didSelectObjects:)]) { 
        // Check to see if any objects are selected 
        NSArray *selectedObjects = [mapView visibleObjectsAtPoint:location]; 
        // If any objects were selected, treat the tap as a selection 
        if (selectedObjects.count > 0) { 
            [mapView.delegate mapView:mapView didSelectObjects:selectedObjects]; 
        } 
    } 
}
