推荐答案

您可以在设置 allowsCameraControl = true 后禁用/修改或添加更多识别器.

You can disable/modify or add more recognisers after setting allowsCameraControl = true.

if let recognizers = scnview.gestureRecognizers {  
        for gestureRecognizer in recognizers {
            if let gesture = gestureRecognizer as? UIPanGestureRecognizer {
                gestureRecognizer.isEnabled = false
            }
        }
    }
