Parameters

  • cameraDeviceView:

    The camera device view that sent the message.

    The camera file.

  • url:

    The URL to save the data.

  • data:

    The data.

  • error:

    Any errors encountered during downloading.

Discussion

If the IKCameraDeviceView transferMode property is IKCameraDeviceViewTransferMode.fileBased then camera file will have been saved to url. The URL will be a complete path to save the file, including a ‘sequence number’ if the file already exists.

If the transferMode is IKCameraDeviceViewTransferMode.memoryBased then the data parameter contains the image data and can be handled as appropriate for your application.

In case of an error, the passed data (both url and data) will be NULL and error (which may come directly from the camera module / or the ImageCaptureCore framework) will describe why the download or save failed.
