oovoo无法打开摄像头

Question

我正在尝试将ooVoo连接到我的应用程序中。(*ooVoo是视频聊天框架)但我被困在了第一阶段，那就是打开预览。它只显示空白的黑色。我遗漏了什么？

以下是我的代码。(我也在这里上传了我的项目https://github.com/lossefanya/OovooTest)

self.oovooClient = [ooVooClient sharedInstance];
[self.oovooClient authorizeClient:OOVOO_TOKEN completion:^(SdkResult *result) {
    [self.oovooClient.Account login:@"tester" completion:^(SdkResult *result) {
        VideoPanel *videoPanel = [[VideoPanel alloc] initWithFrame:CGRectMake(0, 0, 300, 300)];
        self.oovooClient.AVChat.delegate = self;
        self.oovooClient.AVChat.VideoController.delegate = self;
        [self.oovooClient.AVChat.VideoController bindVideoRender:nil render:videoPanel];
        [self.oovooClient.AVChat.VideoController openCamera];
        [[KGModal sharedInstance] showWithContentView:videoPanel];
    }];
}];

仅供参考，我已经阅读并遵循了他们的文档和示例代码。https://github.com/oovoodev/Documentation/blob/master/iOS%20Documentation/Development%20Guide%20-%20iOS.md

我不明白为什么。但是我发现ooVoo VideoPanel应该有父视图。像下面这样

self.oovooClient = [ooVooClient sharedInstance];
[self.oovooClient authorizeClient:OOVOO_TOKEN completion:^(SdkResult *result) {
    NSLog(@"ooVoo init: %@", result);
    [self.oovooClient.Account login:@"tester" completion:^(SdkResult *result) {
        NSLog(@"ooVoo login: %@", result);
        UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 300, 300)];
        VideoPanel *videoPanel = [[VideoPanel alloc] initWithFrame:CGRectMake(0, 0, 300, 300)];
        [view addSubview:videoPanel];
        self.oovooClient.AVChat.delegate = self;
        self.oovooClient.AVChat.VideoController.delegate = self;
        [self.oovooClient.AVChat.VideoController bindVideoRender:nil render:videoPanel];
        [self.oovooClient.AVChat.VideoController openCamera];
        [[KGModal sharedInstance] showWithContentView:view];
    }];
}];
