如何禁用ARCoachingOverlayView的自动激活？

问题描述

我正在将ARCoachingOverlayView添加到我的ARView中，如下所示

let coachingOverlayTemp = ARCoachingOverlayView()
coachingOverlayTemp.delegate = self
coachingOverlayTemp.session = self.session
coachingOverlayTemp.goal = .horizontalPlane
coachingOverlayTemp.activatesAutomatically = true
coachingOverlayTemp.translatesAutoresizingMaskIntoConstraints = false
self.addSubview(coachingOverlayTemp)

coachingOverlay = coachingOverlayTemp // I store it to a variable on the class

以后，如果我这样做

coachingOverlay.activatesAutomatically = false

无效。coachingOverlay继续正常工作。

如何在需要时立即禁用它？

推荐答案

实例方法setActive(_:animated:)控制指导是否正在进行。

open func setActive(_ active: Bool, animated: Bool)

这是Apple documentation所说的：

// SMOOTHLY
ARCoachingOverlayView().setActive(false, animated: false)

或者您可以使用isHiddenProperty：

// ABRUPTLY
ARCoachingOverlayView().isHidden = true
