带AVPlayer的SKVideoNode正在播放，但在iOS 9.0上不可见

我对Xcode 7.0（7A220）和iOS 9.0有问题。我添加了一个带有

AVPlayer

和

SKVideoNode

的视频（.mp4或mov，两者都不工作）。在iOS 8.4的模拟器上，它工作正常，但在iOS 9.0（也是模拟器）上，视频不会显示。不过我能听到音频

我的

游戏场景

（属于

SKScene类

）中的代码：

在

UIViewController

中，我有：

- (void)viewDidLoad
{
    [super viewDidLoad];

    // Configure the view.
    SKView * skView = (SKView *)self.view;
    skView.showsFPS = YES;
    skView.showsNodeCount = YES;

    /* Sprite Kit applies additional optimizations to improve rendering performance */
    // I have set this to NO, but it doesn't help
    skView.ignoresSiblingOrder = NO;

    // Create and configure the scene.
    CGRect rect = [[UIScreen mainScreen] bounds];
    GameScene *videoScene = [[GameScene alloc] initWithSize:rect.size];
    videoScene.scaleMode = SKSceneScaleModeAspectFill;

    GameScene *scene = [GameScene unarchiveFromFile:@"GameScene"];
    scene.scaleMode = SKSceneScaleModeAspectFill;

    // Present the scene.
    [skView presentScene:videoScene];
}

---

因此，应用程序没有崩溃，视频正在播放（我能听到），但视频仅在iOS 9上不可见。有人有办法修复它吗？

检查视图层次结构以查看视图的框架player@VarunNaharia我没有看到任何东西，只有UIWindow和SKView。我不认为精灵在里面是可见的。使用真实的设备，iOS9模拟器在SKVideoNode中不会显示任何东西。。。还有其他恼人的bug，比如自动开始播放。。。

- (void)viewDidLoad
{
    [super viewDidLoad];

    // Configure the view.
    SKView * skView = (SKView *)self.view;
    skView.showsFPS = YES;
    skView.showsNodeCount = YES;

    /* Sprite Kit applies additional optimizations to improve rendering performance */
    // I have set this to NO, but it doesn't help
    skView.ignoresSiblingOrder = NO;

    // Create and configure the scene.
    CGRect rect = [[UIScreen mainScreen] bounds];
    GameScene *videoScene = [[GameScene alloc] initWithSize:rect.size];
    videoScene.scaleMode = SKSceneScaleModeAspectFill;

    GameScene *scene = [GameScene unarchiveFromFile:@"GameScene"];
    scene.scaleMode = SKSceneScaleModeAspectFill;

    // Present the scene.
    [skView presentScene:videoScene];
}
