重播套件返回错误"RPRecordingErrorFailedToStart"

我正在尝试将录制功能添加到我的ReplayKit基于C++的游戏中。我在游戏代码中检查iOS版本是否为9.0或更高版本，如果是，我会调用RecordReplayIOS::startRecording()，然后ReplayKit应该开始录制。

由于某些原因，startRecordingWithMicrophoneEnabled函数总是返回错误-5803，根据API文档，这意味着RPRecordingErrorFailedToStart。你知道我做错了什么吗？

RecordReplayIOS.hpp:

#define __RECORD_REPLAY_IOS_HPP__
class RecordReplayIOS {
public:
    static bool canRecord();
    static void startRecording();
    static void stopRecording();
};
#endif
