如何快速將錄像保存到文檔目錄？

Question

我已經編寫了這段代碼來錄制視頻，並且想將filePath保存到documents目錄，該怎么辦？

func startRecording() {
    var currentDateTime = NSDate()
    var formatter = NSDateFormatter()
    formatter.dateFormat = "MM-dd-yyyy, hh:mm:ss a"
    var recordingName = formatter.stringFromDate(currentDateTime) + ".mp4"
    var pathArray = [dirPath, recordingName]
    let filePath = NSURL.fileURLWithPathComponents(pathArray)

    if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.Camera) {
        videoRecorder = UIImagePickerController()
        videoRecorder.delegate = self
        videoRecorder.sourceType = UIImagePickerControllerSourceType.Camera
        videoRecorder.mediaTypes = [kUTTypeMovie]
        videoRecorder.videoMaximumDuration = 3600.0
        videoRecorder.startVideoCapture()
    }
}

我之前做過，您可以使用NSFileHandle做到這一點

NSFileHandle（forWritingToURL：filePath，錯誤：無）

這個對我有用。
