ios - カメラに .Armodel ファイルが読み込まれず、kudan で白い画面しか表示されない

Question

このデモを使用するときに、xcode 8.0 と os バージョン 9.3.5 を使用しましたが、カメラを開くことができません。

最初にオブジェクトを配置すると、この画面は正常に動作しますが、完了ボタンをクリックすると、白い画面が表示された後、この画面には何も表示されません。

これが私のスクリーンショットです

ここに私のコードがあります

mapViewcontroller.m

- (IBAction)progressButton:(id)sender
{
    if (self.touchPin) {
        [self performSegueWithIdentifier:@"showGPSDemo" sender:self];
    }
}

#pragma mark - Navigation

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    if ([[segue identifier] isEqualToString:@"showGPSDemo"]) {
        // Set model coordinate to position of the map pin.
        CameraViewController *viewController = [segue destinationViewController];

        CLLocationCoordinate2D touchPinCoordinate = self.touchPin.coordinate;

        viewController.objectCoordinate = [[CLLocation alloc] initWithLatitude:touchPinCoordinate.latitude longitude:touchPinCoordinate.longitude];
    }
}

CameraViewController.com

- (void)setupContent
{
    // Initialise and start the GPS Manager.
    ARGPSManager *gpsManager = [ARGPSManager getInstance];
    [gpsManager initialise];
    [gpsManager start];

    // Initialise a GPSNode with coordinate provided from the map.
    ARGPSNode *gpsNode = [[ARGPSNode alloc] initWithLocation:self.objectCoordinate];

    // Point the GPS Node due east.
    [gpsNode setBearing:90];

    // Must add GPSNode as a child to the GPS Manager world.
    [gpsManager.world addChild:gpsNode];

    // Import the model.
    ARModelImporter *modelImporter = [[ARModelImporter alloc] initWithBundled:@"bloodhound.armodel"];

    // The ARModel node represents all external contents relating to the model e.g.animations, textures.
    ARModelNode *modelNode = [modelImporter getNode];

    // Add the modelNode as a child to the GPSNode.
    [gpsNode addChild:modelNode];

    // Add the texture to the 3D model.
    ARTexture *modelTexture = [[ARTexture alloc] initWithUIImage:[UIImage imageNamed:@"bloodhound.png"]];

    // Setup the object material.
    ARLightMaterial *modelMaterial = [[ARLightMaterial alloc] init];
    modelMaterial.colour.texture = modelTexture;
    modelMaterial.ambient.value = [ARVector3 vectorWithValuesX:0.5 y:0.5 z:0.5];
    modelMaterial.diffuse.value = [ARVector3 vectorWithValuesX:0.5 y:0.5 z:0.5];

    // Apply to the model.
    for (ARMeshNode *meshNode in modelNode.meshNodes) {
        meshNode.material = modelMaterial;
    }

    // Scale the model to the correct height of Big Ben from model height. Units of the GPSManager world are meters, model is 11008 units high in object space.
    [modelNode scaleByUniform:(96.0 / 11008.0)];

    self.gpsNode = gpsNode;
}
