Question

我有通常的视图控制器，我想显示包含SCNView的其他ViewController

如果我使用presentViewController或showViewController，那么它无效。它马上结束了。我的意思是，场景没有显示出来。

感谢您的回答！

抱歉我的英文不好

让我们描述一下我的项目。我有包含主菜单的ViewContrioller，我有包含骰子的SCNView。这是包含SCNView的ViewController：

    self.scene = [SCNScene sceneNamed:@"dice.dae"];
    self.scene.physicsWorld.gravity  = SCNVector3Make(0, -16, 0);
    self.scene.physicsWorld.speed = 2.5;

    self.cameraNode = [SCNNode node];
    self.cameraNode.camera = [SCNCamera camera];
    [self.scene.rootNode addChildNode:self.cameraNode];
    self.cameraNode.position = SCNVector3Make(0, 20, 20);
    self.cameraNode.transform = SCNMatrix4Rotate(self.cameraNode.transform,M_PI/3.0, -5, 0, 0);


    self.diceNode = [self.scene.rootNode childNodeWithName:@"dice" recursively:YES];

    SCNPhysicsBody* diceBody = [SCNPhysicsBody bodyWithType:SCNPhysicsBodyTypeDynamic shape:[SCNPhysicsShape shapeWithNode: self.diceNode options:nil ]];
    self.diceNode.physicsBody = diceBody;
    CGFloat zVelocity = arc4random()%10+5;
    CGFloat xVelocity = arc4random()%5;
    self.diceNode.physicsBody.velocity = SCNVector3Make(xVelocity, 0, -zVelocity);
    CGFloat xAngVelocity = arc4random()%12 + 5;
    CGFloat yAngVelocity = arc4random()%4 + 1;
    CGFloat zAngVelocity = arc4random()% 13 + 9;
    self.diceNode.physicsBody.angularVelocity = SCNVector4Make(-xAngVelocity, yAngVelocity, -zAngVelocity, 0.8);
    self.diceNode.physicsBody.mass = 100.0;
    self.diceNode.physicsBody.friction = 1;
    SCNNode *field = [self.scene.rootNode childNodeWithName:@"field" recursively:YES];
    field.physicsBody = [SCNPhysicsBody bodyWithType:SCNPhysicsBodyTypeStatic shape:[SCNPhysicsShape shapeWithNode:field options:nil]];
    field.physicsBody.friction = 1;
     self.scnView = (SCNView *)self.view;
    self.scnView.frame = self.view.frame;
    self.scnView.scene = self.scene;
    self.scnView.allowsCameraControl = YES;
    self.scnView.showsStatistics = YES;
    self.scnView.backgroundColor = [UIColor blackColor];
    self.scnView.delegate = self;

我尝试从主菜单

显示此ViewController

  DiceScene* dice = [[DiceScene alloc] init];
    [self presentViewController:dice animated:YES completion:^{
        NSLog(@"completion");
    }];

我的DiceScene没有显示，它立即完成而没有错误。

试试这个：

ViewController中的

：

DiceScene* dice = [[DiceScene alloc] init];
[self setView:dice];

从其他ViewController呈现SCNView
