Disable camera panning in SceneKit

Question

If I am using the default camera control in SceneKit, is there a way to disable the two fingered pan function and leave the others as they are?

I want users to be able to rotate and zoom an object, but not move it at all.

Answer 1

The sceneView already has a UIPanGestureRecognizer attached. If you modify its maximumNumberOfTouches to be 1, you can disable the pan gesture.

for reco in sceneView.gestureRecognizers! {
    if let panReco = reco as? UIPanGestureRecognizer {
        panReco.maximumNumberOfTouches = 1
    }
}

Answer 2

不，您必须制作自己的相机并使用手势识别器。
