Answer 1

如果您尝试通过在应用程序中配置 AVCaptureSession 来运行相机会话，它会根据设备格式支持的 ColorSpaces 和当前 AVCaptureSession 拓扑自动调整 AVCaptureDevice 的 activeFormat 和 activeColorSpace 属性。尝试将 AVCaptureSession 类的属性“automaticallyConfiguresCaptureDeviceForWideColor”设置为 false。

captureSessionInstance.automaticallyConfiguresCaptureDeviceForWideColor = false

当您不在该视图中时，还可以停止正在运行的捕获会话，并在需要时重新启动。

captureSessionInstance.stopRunning()

captureSessionInstance.startRunning()
