Ios iPad中未显示isgl3d pod文件

我正在尝试使用ISGL3D框架将POD文件3d对象（使用从Blender导出）导入我的ipad。我没有收到任何错误，但我的ipad只显示黑色屏幕。我试着一行一行地调试，这似乎是相机的问题

以下是我在HelloWorldView中的代码：

- (id) init {

if ((self = [super init])) {

    container = [[self.scene createNode] retain];

    // Import pod data
    _podImporter = [Isgl3dPODImporter podImporterWithFile:@"ee.pod"];
    Isgl3dLight * light  = [Isgl3dLight lightWithHexColor:@"000000" diffuseColor:@"FFFFFF" specularColor:@"FFFFFF" attenuation:0.001];
    light.position = iv3(0, 0, 2);
    light.renderLight = YES;
    [container addChild:light];
///Problem seems to start from below
    [self.camera removeFromParent];
    self.camera = [_podImporter cameraAtIndex:0];
    [self.scene addChild:self.camera];


    role01 = [_podImporter meshNodeWithName:@"Sphere"];
    [vound addChild:role01];

    [self schedule:@selector(tick:)];
}
return self;}

我试图在没有导入器相机的情况下只添加3d对象，但遇到了一个例外，它无法定位我的3d对象。请帮忙，谢谢

我花了一段时间才发现问题：

我漏掉了这个代码：

[_podImporter buildSceneObjects];

因此，让podImporter工作的正确代码是

- (id) init {

if ((self = [super init])) {

container = [[self.scene createNode] retain];

// Import pod data
_podImporter = [Isgl3dPODImporter podImporterWithFile:@"ee.pod"];

[_podImporter buildSceneObjects];///<--- Put it here or anywhere before the camera code

Isgl3dLight * light  = [Isgl3dLight lightWithHexColor:@"000000" diffuseColor:@"FFFFFF" specularColor:@"FFFFFF" attenuation:0.001];
light.position = iv3(0, 0, 2);
light.renderLight = YES;
[container addChild:light];
[self.camera removeFromParent];
self.camera = [_podImporter cameraAtIndex:0];
[self.scene addChild:self.camera];


role01 = [_podImporter meshNodeWithName:@"Sphere"];
[vound addChild:role01];

[self schedule:@selector(tick:)];

-（id）init{
if（（self=[super init]））{
容器=[[self.scene createNode]retain]；
//导入pod数据
_podImporter=[Isgl3dPODImporter-podImporterWithFile:@“ee.pod”]；
[_podimporterbuildsceneobjects]///
