Swift ARKit如何完全杀死ARSession? [英] Swift ARKit How do you fully kill an ARSession?

问题描述

我有一个运行ARSession的ARSCNView.您可以使用session.pause()暂停会话，但是仍然有效，它将使会话继续运行.我尝试通过从其超级视图中删除ARSCNView来解除分配. ARSCNView确实已取消分配，但ARSession之后仍在运行！！您也不能将nil分配给ARSession.我可以看到ARSessionDelegate的

I have an ARSCNView running an ARSession. You can pause the session with session.pause() sure, but that still in effect, leaves the session running. I have tried deallocating the ARSCNView by removing it from its superview. The ARSCNView indeed deallocates but the ARSession is still running afterwards!! You can't assign nil to ARSession either. I can see the ARSessionDelegate's

func session(_ session: ARSession, didUpdate frame: ARFrame) 

仍在被呼唤！

完成后如何用ARKit彻底擦拭干净?

How do you completely wipe the slate clean with ARKit once you have finished with it?

有可能吗?

推荐答案

目前，您还不能这样做.

但是，有一种解决方法:将ARSCNView设为一次性.

However, there is a work-around: you make the ARSCNView disposable.

离开AR时，请先暂停ARSession.然后取消分配整个ARSCNView层次结构&将ARSCNView设置为nil以获得良好的效果.重建整个ARSCNView层次结构，并在需要返回到AR时开始新的会话.

On leaving AR, first pause the ARSession. Then deallocate the entire ARSCNView hierarchy & set ARSCNView to nil for good measure. Rebuild the entire ARSCNView hierarchy and start a new session whenever you need to go back to AR.

var ARview: ARSCNView?

func punchTheClown() {

    ARView?.session.pause()
    ARView?.removeFromSuperview()
    ARView = nil

}

应用程序的其他非AR区域通常位于与ARSCNView处于同级的单独视图层次结构中.我期待Apple提供实际的stopSession()功能，因此我们所有人都可以在此期间不再需要对TheClown打孔.

Other non-AR areas of your app would typically be in a separate view hierarchy at the same sibling level as your ARSCNView. I look forward to Apple providing an actual stopSession() function, so we can all stop having to punchTheClown in the meantime.
