在MKMapView上模糊 [英] Blur on MKMapView

问题描述

我知道之前曾有人问过这个问题，但是我试图在我的应用程序的地图视图中添加模糊效果.我尝试过的所有操作都只是对地图进行着色，包括如下代码:

I know this question has been asked before, but I am trying to put a blur on a map view in my app. Everything I've tried just tints the map including code like this:

var darkBlur = UIBlurEffect(style: UIBlurEffectStyle.Dark)
var blurView = UIVisualEffectView(effect: darkBlur)
blurView.frame = mapView.bounds
mapView.addSubview(blurView)

有没有一种方法可以使地图模糊?

Is there a way to actually blur the map?

推荐答案

您是否尝试将blurView添加到mapView的超级视图中?

Did you try adding blurView to mapView's superview?

在Playground上对我来说效果很好

Works fine for me in Playground:
