Question

我们在iOS9上部署时使用SceneKit的应用程序遇到了问题。该应用程序在iOS8.0-8.4上运行良好，但在iOS9上部署时，它会立即崩溃。查看崩溃日志，我们在一个线程中看到了一个EXC_BAD_ACCESS异常。特定错误指出com.apple.scenekit.renderingQueue.SCNView Thread 11崩溃。认为它与场景的复杂性有某种关系，我们将场景简化为三维盒子，应用程序仍然崩溃。呈现框的代码如下。崩溃似乎非常简单。并且非常奇怪的是，这在iOS9之前的所有内容上运行良好，并且在iOS9的模拟器上运行良好。它只在部署时崩溃。（这是一个企业应用程序）。

崩溃发生在以下代码行： [scene.rootNode addChildNode：boxNode];

我错过了什么？谢谢你的帮助。

@implementation TreasureChestViewController
@synthesize sceneView; 

 - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
 {
     self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
     if (self) {
     // Custom initialization

     }
     return self;
 }

- (void)viewDidLoad
{
    [super viewDidLoad];


    // Create the SCNView

}

-(void) viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];

    // Add scene an empty scene
    scene = [SCNScene scene];

    // Set the scene to the view
    sceneView.scene = scene;

    // Create and add a camera to the scene
    SCNNode *cameraNode = [SCNNode node];
    cameraNode.camera = [SCNCamera camera];
    cameraNode.position = SCNVector3Make(0,15, 30);
    [scene.rootNode addChildNode:cameraNode];

    // Create and add a light to the scene
    SCNLight *spotLight = [SCNLight light];
    spotLight.type = SCNLightTypeSpot;
    spotLight.color = [UIColor whiteColor];
    SCNNode *spotLightNode = [SCNNode node];
    spotLightNode.light = spotLight;
    spotLightNode.position = SCNVector3Make(0, cameraNode.position.y, 20);

    [cameraNode addChildNode:spotLightNode];

    // A square box
    CGFloat boxSide = 15.0;
    SCNBox *box = [SCNBox boxWithWidth:boxSide
                                height:boxSide
                                length:boxSide
                         chamferRadius:0];
    SCNNode *boxNode = [SCNNode nodeWithGeometry:box];
    // boxNode.transform = CATransform3DMakeRotation(M_PI_2/3, 0, 1, 0);

    [scene.rootNode addChildNode:boxNode];

}

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation

    return YES;
